What would be the electron configuration for neutral oxygen? Please show what energy level each electron is in using the electron diagonal filling rule do not use noble gas configuration.

Answers

Answer: 1s2 2s2 2p4

Explanation:

Recall the number of electrons an orbital can have:

s orbitals have 2, p orbitals have 6, d orbitals have 10, f orbitals have 14, and so on.

Oxygen in its neutral state would have 8 electrons.

To summarize the diagonal filling order, it goes from the least energy level to the most, and the orbital with the least amount of orbitals to the most.

So, the order for this will go from 1 and end at 2 (for energy level,) then s, s again (as energy level 1 has 1s orbital only,) and p.

So, the first energy level, 1s2 (2 electrons), leaves the remaining six electrons.

Completely fill the s orbital (another 2 electrons), and the remaining 4 electrons will be in the respective p orbital.

Thus, it is 1s2 2s2 2p4.

5. CCC Patterns Look at the melting points for the metals in the fourth and fifth periods of the
periodic table in the figure. Describe the general pattern in the relationship between a metal's
position in the table and its melting point.

Answers

Periodic trends are particular patterns that appear in the periodic table and highlight various characteristics of a certain element, such as its size and electrical capabilities. Electronegativity, ionization energy, electron affinity, atomic radius, melting temperature, and metallic nature are important periodic trends.

What is the general pattern in the relationship between a metal's position in the table and its melting point?

Within a period, the elements' ionization energies tend to rise from left to right. Valence shell stability is to blame for this.

In general, an element's ionization energy falls from top to bottom within a group. The reason for this is electron shielding.

The graph shows that the entire valence shells of the noble gases give them extremely high ionization energy. Keep in mind that among all the elements, helium has the highest ionization energy.

Within a time frame, electron affinities shift from left to right. The shrinkage of atomic radius is to blame for this.

Within a group, electron affinity diminishes from top to bottom. The rise in atomic radius is to blame for this.

This results from an overall rise in the amount of protons and electrons throughout time. Since each proton exerts more force than each electron, electrons are drawn inward and reduce the radius of the atom.

Within a group, atomic radius grows from top to bottom. The reason for this is electron shielding.

What is the mass of a 8.45 m3 piece of copper?

Answers

The mass of a 8.45 m3 piece of copper is 7537.4 grams.

What is mass?

Mass is described as a dimensionless quantity representing the amount of matter in a particle or object.

density of copper =8.92g/cm^3

volume = 8.45 x 100 cm^3

mass =  (8.45 x 100) x 8.92

mass = 7537.4 grams.

The relationship between mass, density and volume is that density offers a convenient means of obtaining the mass of a body from its volume or vice versa.

The Law of Conservation of Matter states that in a closed system, matter cannot be created or destroyed. This means that atoms can NOT just appear or disappear. The mass will not change in a closed system.

This, however, is NOT what we observed. We observed that the mass of the substance in our measuring tray increased after burning.

Why do you think this happened? Where did the extra mass come from?



REMEMBER: Energy (light, heat, motion, etc.) is not made of atoms so has no mass.

RESOURCE: Access your online textbook through CLEVER, click to get the blue ribbon across the top of the page and go to the Table of Contents. Scroll down to Lesson 9 Conservation of Matter and select "Extending Your Knowledge: Mass and Matter"

Answers

Answer:

The Law of Conservation of Matter states that in a chemical reaction, matter is not created or destroyed. However, it is possible for the mass of a substance to change during a chemical reaction, as you observed.

When a substance burns, it reacts with oxygen in the air to form new compounds. For example, when wood burns, it reacts with oxygen to form water and carbon dioxide. The mass of the wood plus the mass of the oxygen is equal to the mass of the water and carbon dioxide produced.

In this case, the extra mass that you observed came from the oxygen that reacted with the wood. Oxygen has mass, and when it reacts with the wood, the mass of the resulting compounds is greater than the mass of the starting materials.

It's important to note that energy is not a form of matter, and therefore has no mass. However, energy can be converted into matter and vice versa, according to the famous equation E=mc^2, where E is energy, m is mass, and c is the speed of light. This equation demonstrates that mass and energy are fundamentally connected and can be converted into each other under certain conditions.

a. What mass of the excess reactant remains after the reaction occurred?
b. If you conducted an experiment and 11.5 grams of Fe(s) was formed what would be the percent yield?
c. If the percent yield for the process to obtain 75 kg of CO2 was 80.7%, how many kg of CO is needed?

Answers

The mass of the excess reactant ([tex]Fe_2O_3[/tex] that remains after the reaction would be 30.96 gramsThe percent yield would be 86.28%The amount of CO needed would be 59.14 kg.

Stoichiometric problems

From the balanced equation of the reaction, the mole ratio of the reactants is 1:3.

Mole of 50.0 g [tex]Fe_2O_3[/tex] = 50/160 = 0.3125 mol

Mole of 10.0 g CO = 10/28 = 0.3571 mol

Stoichiometric equivalent of  [tex]Fe_2O_3[/tex] = 0.3571/3 = 0.1190 mol

In other words,  [tex]Fe_2O_3[/tex] is in excess.

Excess mole = 0.3125 - 0.1190 = 0.1935 mol

Mass of 0.1935 mol [tex]Fe_2O_3[/tex] = 0.1935 x 160 = 30.96 grams

Mole ratio of CO to Fe = 3:2

Equivalent mole of Fe that would be formed = 0.3571 x 2/3

                                                                          = 0.2381 mol

Mass of 0.238 mol Fe = 0.238 x 56 = 13.328 grams

Percent yield of Fe = 11.5/13.328 x 100 = 86.28%

Mole of 75 gk CO2 = 75000/44 = 1704.55 mol

Mole ratio of CO2 and Co = 1:1

Equivalent mole of CO = 1704.55 mol

Mass of 1704.55 mol CO = 1704.55 x 28 = 47.73 kg

80.7% = 47.73 kg

100% = 100 x 47.73/80.7

If the other substance is a carbonate, name the gas given off. Even though A is insoluble a clear solution is given off, explain why.​

Answers

Answer:

From the information provided, it seems likely that substance A is an acid, and substance B is a carbonate. The fact that mixing the two substances results in bubbles or effervescence, and that a clear solution is formed, suggests that a chemical reaction is taking place.

Acids and carbonates react together to form a salt, water, and carbon dioxide gas. The reaction is as follow:

Acid + Carbonate → Salt + Water + Carbon Dioxide

The carbon dioxide gas forms bubbles in the solution and causes effervescence, and the clear solution formed is due to the fact that both the acid and the carbonate have reacted together to form the salt and water. This reaction is acid-base neutralization reaction as the acid and base will neutralize each other.

As for the acid, since it is said that B gives pH 3 solution after dissolved, it can be inferred that it is not an acid, otherwise it would be acidic. Therefore A which is insoluble is the acid.

As for the gas given off, it's Carbon dioxide.

the enthaply of formation of water is -285.8kj/mol. what can be inferred from this statement

Answers

Answer:   It takes 285.8 kJ of energy to form one mole of water

Explanation:

The enthalpy of formation of a substance is the change in enthalpy that occurs when a substance is formed from its elements in their standard states. The enthalpy of the formation of water is -285.8 kJ/mol, which means that it takes 285.8 kJ of energy to form one mole of water from its elements (hydrogen and oxygen) under standard conditions. This value is negative, which means that the formation of water releases energy. This is why water is often referred to as an "exothermic" substance because it releases energy when it is formed. The negative value of the enthalpy of formation for water can be explained by the fact that the bonds formed between hydrogen and oxygen atoms in water are stronger than the bonds between hydrogen and oxygen atoms in the individual elements. This means that it takes less energy to break the bonds in the elements than it releases when the bonds in water are formed, resulting in a net release of energy.

What ions are formed with AgNO3 dissolves in water? How does water stabilize the ions?

Answers

Answer:

Explanation:

In water, silver nitrate (AgNO3) dissolves to generate the ions Ag+ (silver) and NO3- (nitrate). When the substance is dissolved in water, the ions are separated and become solvated, or surrounded by water molecules. Water molecules' oxygen atoms join the metal ion in a coordinate covalent bond that gives the metal ion a pair of electrons. By preventing it from interacting with other ions or molecules in the solution, this aids in stabilising the metal ion. As a result of their hydrogen bonds with the water molecules around them, the nitrate ions are likewise stabilised in solution.

Reducing the risk of human error by having a computer do tasks can increase the safety of transportation: Airplanes have systems that automate takeoffs and landings. Some cars can parallel park themselves. Cargo ships have autopilots. Mazes offer a challenge that can be directly translated to these situations. In this task, you are developing navigation software for a company that makes robotic systems that can direct themselves. As a first-level test of the robot you are developing, you will have it navigate a maze. North West East South B:The arrow at the maze entrance indicates that the robot will be heading east when it enters the maze. When programming the robot, let the complex number d represent the direction the robot is facing. As the robot changes direction, the value of d will also change; so, the value of d is dependent on where the robot is in the maze. At the start of the maze, what is the value of d? C;While navigating the maze, the robot will need to be able to turn left and right. The first turn the robot will make is a left turn.
