What is true about Carbon-14 and Carbon-12?a. The mass of the Carbon-14 sample is less than the Carbon-12 sample, but the reactivity of both samples was the same.
b. The mass of the Carbon-14 sample is greater than the Carbon-12 sample, but the reactivity of both samples was the same .
c. The reactivity of the Carbon-14 sample is less than the Carbon-12 sample, but the mass of both samples was the same.
d. The reactivity of the Carbon-14 sample is greater than the Carbon-12 sample, but the mass of both samples was the same.

Answers

Answer 1

Answer:

Answer:

Explanation:

Correct: b. The mass of the Carbon-14 sample is greater than the Carbon-12 sample, but the reactivity of both samples was the same .

- C-14 has two additional neutrons, so is heavier than C-12. The chemical properties will be the same, however.

Which physical state of matter exhibits the greatest change in volume with changes or temperature or pressure?

Answers

It’s the gas physical state that shows the greatest change in volume and changes in temperature or pressure. Because gas is the matter that is composed of loose particles but can be compressed. Since gas contains loose molecules, the molecules can freely move in a certain object, so when physical change happens, it exhibit greatest change. Gas also follow the shape of its container and can expand in order to fill its container. It has no definite volume or shape.

Van der Waals forces can best be describes as attrctive or repulsive forces that are formed

Answers

Van der Waals forces can best be describes as attractive or repulsive forces that are formed after bonding. The type of bonding will help us determine what will be the phase of the compound. Just like in liquids, attractive forces are caused by van der Waals bonds.

A sample of calcium oxide (CaO) has a mass of 2.80 g. The molar mass of CaO is 56.08 g/mol. How many moles of CaO does this sample contain?

Answers

Answer is "0.05 mol".

Explanation;

We can do calculation by using a simple formula as

n = m/M

Where, n is the number of moles of the substance (mol), m is the mass of the substance (g) and M is the molar mass of the substance (g/mol).

Here,

n = ?

m = 2.80 g

M = 56.08 g/mol

By substitution,

n = 2.80 g /56.08 g/mol

n = 0.0499 mol ≈ 0.05 mol

What is the chemical equation of ccl4, please explain thank you! :-D

Answers

It could be
C + 2Cl2 ➡️ CCl4
I decided this because I believe this is the only way you could make this a balanced equation. To be a balanced equation Both sides of the equation has the same number of atoms for each element. Carbon has 1 atom and chlorine has 4.
