Answer:
compound
Explanation:
because it is made up of pure substance consists of atom
The new volume of a gas at STP that occupies 16L of space is 27.43L.
<h3>HOW TO CALCULATE VOLUME?</h3>
The volume of a given gas can be calculated using the following expression:
P1V1/T1 = P2V2/T2
Where;
- P1 = initial pressure
- P2 = final pressure
- V1 = initial volume
- V2 = final volume
- T1 = initial temperature
- T2 = final temperature
1 × 16/273 = 2.6 × V2/468
16/273 = 2.6V2/468
0.0586 × 468 = 2.6V2
V2 = 27.43
Therefore, the new volume of a gas at STP that occupies 16L of space is 27.43L.

To determine this, you can look at the molecular weight of that particular atom which is found on the periodic table. Carbon has a molar mass of 12.01 grams / mole. Sulfur has a molar mass of 32.06 grams / mole. This means one mole of carbon weighs 12.01 grams and one mole of sulfur weighs 32.06 grams. Therefore, one mole of carbon atoms has a smaller mss than one mole of sulfur atoms.
Answer: B.They are arranged in energy levels
Explanation: Electrons orbit around the nucleus of an atom, and are not spread around equally throughout an atom because there are a different amount of electrons that can fit in each energy level or electron shell (both are the same thing). For example the first energy level can hold up to 2 electrons, the second shell can hold up to 8 electrons, the third can hold up to 18, and so on represented by the equation 2(n^2)
