What is the mass of the ethyl alcohol that exactly fills a 400.0 mL container? The density of ethyl alcohol is 0.789 g/mL.

Answers

Answer:

g = (0.789 g/mL) (200.0 mL) = 158

The mass of ethyl alcohol that exactly fills 400 ml of container is 315.6 grams.

How is mass related to density?

Formula of density is given as , density =mass/volume

∴mass=density×volume

From the formula it is evident that density and mass are directly proportional while density and volume are inversely proportional.

From the given data, volume=400 ml and density =0.789 g/ml

∴by the formula,mass=density×volume

mass=0.789×400

mass=315.6 g

Mass and volume are extensive properties that depend on the amount of substance while density is an intensive property and does not depend on amount of substance.

Intensive properties  are properties which are independent,wherein size of particles does not change.These properties cannot be easily computed and are not easily identifiable.

Question:

A 250mL Erlenmeyer flask weighing 55g contains 5g of sodium bicarbonate. To this, an excess, 15g, of acetic acid is added to the flask. While swirling, many bubbles are present. Finally, you stop swirling the flask, and the bubbles stop. You then place this flask on an analytical balance. The mass registers 73g.

How does this final mass compare with the value expected according to the Law of Conservation of mass?

Why do you believe that this comparison exists?

State the Law of Conservation of Mass. Do these results break this law? Why?

What changes, if any, could be made to the procedures in this experiment to allow a closer comparison to what the Law of Conservation would expect?

Answers

You should download Socratic it’s a real good app for answers !
At first glance, the final mass does not follow the Law of Conservation of Mass because, according to the law, the final mass should be 75g. This comparison likely occurred because stirring the flask created bubbles, suggesting that one product of the reaction is a gas. The Law of Conservation of Mass states that the mass of the reactants must equal the mass of the products. One product happened to be gas that escaped through the opening of the flask, meaning that the results were not completely accurate and do not break the law. One change to make to the experiment would be to seal the flask closed after adding both reactants to ensure that gas doesn’t escape.

Nancy dumps a mixture of salt, iron filings, and wood shavings into a beaker of water and stirs for 60 seconds. Predict the appearance after she stops stirring and allows the mixture to settle.

Answers

Answer:

When the mixture settles, there will be no visible salt, but she will see the iron shavings at the bottom of the beaker and the woodchips floating.

Explanation:

The salt will dissolve, the iron shavings will sink and the wood chips will float because they're less dense.

The iron filings, and wood shavings will still be visible, and settled at the bottom; and the salt will not be able to be seen anymore, because it would have already dissolved into the water. Please mark if its correct :)

Helium is a "special" element in Group 18 because it does not have 8 valence electrons. Why doesn't helium have 8 valence electrons like all the other elements in group 18?

Answers

C IS THE ANSWER BECAUSE HELIUM HAS JUST 2 ATOMS

Helium only has two electrons which fills the outermost shell

Helium is an element which belongs to a family called noble gas.

Among the noble gas element, helium is the only member with two (2) electrons.

Helium is a s-block element. S-block can only accommodate a maximum of 2 electrons. The two (2) electrons that helium has complete its outermost shell as seen from its electronic configuration below:

He (2) => 1s²

Since the outermost shell of helium is completely filled, it is thus included in the noble gas family (i.e group 18).

Other members of the this group include: Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), Radon (Rn)

which of these pairs of atoms are isotopes
A: scandium-46, titanium-46
B: iron-56, sodium-24
C: chlorine-35, chlorine-37
D: sodium-24, magnesium-24

Answers

The answer is C, because isotopes are two or more of the same element with different atomic masses; so, in this case, the two chlorine atoms are the same molecules but they have different atomic masses, as the “35” and “37” say.

Taking into account the definition of isotopes, the correct answer is option C: chlorine-35, chlorine-37

First of all, all atoms are composed of a central nucleus in which there are positively charged particles, the protons, and neutrally charged particles, the neutrons, around which other negatively charged particles that are electrons move.

That is, atoms are made up of a nucleus (made up of protons and neutrons) and a shell made up of electrons.

On the other side, isotopes are atoms whose atomic nuclei have the same number of protons but different numbers of neutrons.

The atomic number (Z) indicates the total number of protons in the nucleus of a given atom, while the atomic mass (A) is obtained by adding the number of protons and neutrons in a given nucleus.

So, in other words, each isotope of the same element has the same atomic number (Z) but each has a different mass number (A). This means that the different isotopes of the same atom differ from each other only by the number of neutrons. So if a neutron is added to an atom, it becomes an isotope of that chemical element.

So, in this case, the correct answer is option C: chlorine-35, chlorine-37, because the two chlorine atoms correspond to the same element but have different atomic masses, whose values ​​are 35 and 37.

Thermal energy “flows” from warmer areas to colder areas. Heat is a measure of this flow.

True or False

Answers

Answer:

True

Explanation:

Throughout the universe, it's natural for energy to flow from one place to another. And unless people interfere, thermal energy — or heat — naturally flows in one direction only: from hot toward cold. Heat moves naturally by any of three means. The processes are known as conduction, convection and radiation.

The statement, "Thermal energy “flows” from warmer areas to colder areas. Heat is a measure of this flow" is true.

What is thermal energy?

The energy created by heat is referred to as thermal energy. It is created when a body's temperature rises. As a result, the molecules, and atoms start to sprint, move quickly, or crash into one another.

When a substance's temperature rises, heat, a type of energy, is created. Temperature, thermal energy, and heat all relate to one another. Heat always moves from a hot body to a cold body.

The heat or thermal energy in the body increases as the temperature rises, causing the movement of the atoms to accelerate and the atoms to collide. Heat is a variable of thermal energy.

Thus, the statement is true.
