describe an atom: atoms are the basic units of matter. an atom has a dense containing positive and neutral surrounded by mostly empty and negative in the electron

Answers

Answer 1

Atoms are the basic building blocks of matter and are composed of three types of particles: protons, neutrons, and electrons.

The center of an atom, called the nucleus, contains positively charged protons and neutral neutrons. The number of protons in the nucleus is called the atomic number and determines what element the atom is.

Surrounding the nucleus are negatively charged electrons, which occupy shells or orbitals at various distances from the nucleus. The electrons are much lighter than the protons and neutrons and occupy most of the volume of the atom.

In summary, an atom can be described as a dense nucleus containing positively charged protons and neutral neutrons, surrounded by mostly empty space and negatively charged electrons.

How do you determine the freezing point of a solution from its cooling curve?

Answers

Drawing two straight lines connecting the data points above and below the freezing point allows one to infer the solution's freezing point from the graph.

The freezing point of the solution is the temperature that corresponds to the point where the two lines converge.

Pure liquid cooling curves are different from solution cooling curves. Since a pure liquid freezes at a constant temperature, a flat, horizontal zone is anticipated on the cooling curve. If the cooling is kept up until all of the liquid has solidified, the temperature will eventually drop to the bath's temperature as the solid cools. On the other hand, for a solution, the temperature drops at a slower pace when freezing takes place. This happens because the solvent is freezing out completely, increasing the concentration of the liquid solution.

8. When 50.0 g of MgCO3 react completely with H3PO4, as shown below, 15.8 g of CO₂ is produced.
Determine the theoretical and percent yield for this reaction?
2 H3PO4 + 3 MgCO3 → Mg3(PO4)2 + 3 CO2 + 3 H₂O

Answers

The theoretical yield for this reaction is 78.61 g of CO2 and the percent yield is 20.0%, when 50.0 g of MgCO3 react completely with H3PO4.

What is theoretical yield?

The theoretical yield is the maximum amount of product that can be produced from a chemical reaction, calculated using the stoichiometry of the reaction equation. It is based on the assumption that the reaction proceeds perfectly, without any loss or waste of reactants, and without any interference from side reactions.

The theoretical yield is calculated by determining the number of moles of each reactant, using the balanced chemical equation to calculate the number of moles of product that can be produced, and then converting this to the corresponding mass of product. It is a useful reference for determining the efficiency of a reaction and for evaluating the quality of the results obtained in a laboratory experiment.

Calculation of Theoretical yield

To calculate the theoretical yield, determine the number of moles of MgCO3 and use the balanced chemical equation to calculate the number of moles of CO2 produced.

The number of moles of MgCO3 is given by:

n(MgCO3) = m(MgCO3) / M(MgCO3)

n(MgCO3) = 50.0 g / 84.31 g/mol

n(MgCO3) = 0.595 mol

Using the balanced chemical equation, calculate the number of moles of CO2 produced:

n(CO2) = 3 * n(MgCO3)

n(CO2) = 3 * 0.595 mol

n(CO2) = 1.785 mol

The mass of CO2 produced can then be calculated:

m(CO2) = n(CO2) * M(CO2)

m(CO2) = 1.785 mol * 44.01 g/mol

m(CO2) = 78.61 g

This is the theoretical yield for the reaction.

The percent yield is a measure of the efficiency of the reaction, and is calculated as the ratio of the actual yield to the theoretical yield, multiplied by 100:

% yield = (actual yield / theoretical yield) * 100

% yield = (15.8 g / 78.61 g) * 100

% yield = 20.0%

Jade's basketball team is choosing a color for their new uniforms. They have a catalog from a vendor with 17 choices. Jade's teammates have already ruled out 9 of the colors. They choose 1 of the remaining colors at random. Assuming that is one of the available colors, what is the probability that the color blue will be chosen?

Answers

The probability that the color blue will be chosen is 2/8 or 1/4, since there are 8 colors remaining after 9 have been ruled out and 2 of those are blue.

Because 9 colors have been eliminated, there are now 17 - 9 = 8 colors remaining. Because two of the eight hues are blue, the chance of selecting blue is 2/8, which simplifies to 1/4.

Another way to look at it is that there are 17 different colors to pick from, and two of them are blue, so the likelihood of selecting blue if all colors were available is 2/17. But, because 9 colors have been ruled out, the probability must be recalculated using the new total of 8, yielding a probability of 1/4.

a sample of 5.10 g of naphthalene (c10h8) is dissolved in 76.1 g of benzene (c6h6). calculate the percent by mass of naphthalene in this solution.

Answers

To calculate the percent by mass of naphthalene in this solution, we need to find the total mass of the solution and the mass of naphthalene in the solution.

The mass of the solution is the sum of the masses of naphthalene and benzene:

mass of solution = mass of naphthalene + mass of benzene

mass of solution = 5.10 g + 76.1 g = 81.2 g

Next, we can find the mass of naphthalene in the solution as a fraction of the total mass and convert it to a percentage:

mass of naphthalene / mass of solution * 100%

(5.10 g) / (81.2 g) * 100% = 6.29%

Answers

The approximate mass of mercury required to fill a 4.0 ounce bottle is 1632 g .

An ounce is approximately 30 cm3, so the calculation is as follows: 13.6 g/cm3 x 30 cm3 = 408 g. Since there are 28.35 g in an ounce, 408 g / 28.35 g = 14.4 ounces.

Therefore, 14.4 ounces x 1632 g/ounce = 1632 g.

The reason why mercury is so dense is because it is a heavy metal composed of molecules that are closely packed together. This makes it very heavy for its volume, and it is one of the densest elements found in nature. It also has a high boiling point, making it ideal for use in thermometers and other temperature measuring instruments. In addition, mercury is a liquid at room temperature, which makes it easy to measure and pour.

The net ionic equation is essentially the most simplified version of a reaction with only the reactants that form the precipitate (the solid). Due to this it is extremely important to properly write your ionic equation first. In your total ionic equation, you forgot to balance the compounds with 2- charges.  The coefficients in your equation is due to the 2- charge of sulfate and 2+  charge of Strontium. Additionally, precipitates are solid which means they do not dissociate. SrSO4 will stay together while KBR which are both spectator ions will dissociate leaving you with the ionic equation below.

Total Ionic Equation: Sr^2 (aq)+  + 2Br ^1- (aq) +2K ^ 1(aq) +  SO4 ^2- (aq) --> SrSO4 (s) + 2K^1+ (aq) + 2Br^1- (aq)

The coefficient of 2 on both K and Br in the products is to ensure that the equation is balanced and that for your net ionic equation, all spectator ions cancel. When you cancel all of the ions that dissociate you are left with the essence of the reaction:

Net Ionic Equation:  Sr^2 (aq) + SO4 ^2- (aq) --> SrSO4 (s)

What is color transmitted?

Light transmits when it penetrates a surface. This can be observed with materials like glass or transparent plastic using visible frequencies. The transmitted light allows us to see through these materials.

Electromagnetic radiation that can be seen by the human eye is known as light or visible light. Typically, visible light is defined as having wavelengths between 400 and 700 nanometers (nm), or frequencies between 750 and 420 terahertz, which fall between the longer-wavelength infrared and the shorter-wavelength ultraviolet (with shorter wavelengths).

The color of the solution is green.

Thus the solution is transmitted green.

The remaining color is absorbed by the solution.

The absorbed colors are violet, red, and orange wavelengths.

AIDS still meets the definition of a pandemic. Your claims should be supported by scientifically complete evidence. Follow the steps provided to research, plan, and create your presentation. This guide about the research process can help. Part A: Ask Questions Begin by creating a list of questions to guide your research and help you form a convincing argument. Your presentation should answer some of these questions: What is the definition of a pandemic? How does a pandemic differ from an endemic or epidemic? What is the life cycle of the HIV virus once it enters the body? How does the genetic code of the virus change? How does HIV affect the body? How do people become infected with HIV? How does AIDS develop from an HIV infection? What are the current infection rates of HIV across the globe? Where is HIV/AIDS most prevalent? What treatments are currently available for HIV/AIDS? Do some regions of the world have better access to treatments than others? What is the average life expectancy for someone with HIV? Does life expectancy differ around the globe? Now write four additional questions about HIV/AIDS that could help strengthen your argument in the presentation. Part B: Find Credible Sources When designing a science presentation, look for credible sources. Science doesnt show bias, but humans do. Avoid sites and articles that provide facts without citing proper scientific evidence. You must be able to identify reliable sites so that the data in your presentation is credible. Use sources that end in .gov, such as CDC.gov. These government sites are reliable sources. You can also use sites ending in .edu. They are usually trustworthy, but sometimes students, not scientists, write content for .edu websites. Always identify the sources author before proceeding. Some .org and .com sites are credible, but its important to verify their authenticity. When reviewing a source, ask these questions: Who is the author? Is this person an HIV or AIDS expert? What is the documents purpose? Does the document state facts that scientists can prove with evidence? Are there opinions in the document? How old is the document? Do other credible sources support the statements in the document? Search for credible websites and note the information they contain. Write down two sources that you will use for your presentation, and cite them using Modern Language Association (MLA) citation methods. Part C: Take Notes In a separate location, take notes from the sources you have identified. The notes will provide details for your presentation. While taking notes from texts and websites, use these reading strategies. In the space provided, write four pieces of information that you intend to use in your presentation. Part D: Organize Your Information After youve gathered research and answered all your questions, create an outline in the answer space. Following these guidelines for writing a five-paragraph essay may help you structure your outline. Be sure to account for the claim youre making in your introduction, and include a works cited page at the end with the authors and websites you consulted. Part E: Select Audio and Video An audiovisual presentation uses pictures and words to clearly present information. These tips will help you effectively build your presentation: Limit text on your slides: Insert key words or phrases that highlight your points instead of typing your entire speech on the slide. When possible, use pictures instead of words: Use representative figures such as pictures, graphs, and charts to depict information or evidence rather than using huge blocks of text. Fill in your speakers notes: Presentation software includes a notes section where you can add speakers notes for your own reference. In this section, you can cover all the details you want to talk without showing them on your slides. Your speakers notes should be clear and coherent enough so that someone else could deliver the presentation to an audience. You must complete your speakers notes to get full credit for the assignment. List two to three audio, video, or photo resources that you wish to use in your presentation and paste them in the provided space. Part F: Create and Deliver Your Presentation Use your outline and the materials youve collected to create your presentation. It should contain 15 to 20 slides. Be sure to proofread and revise your writing to catch any errors in grammar, spelling, logic, or cohesion.
