I’m not too sure because i forgot about this but i thik it’s D, good luck
1. Pressure decreases with increasing volume as the increased volume increases space for molecules to move around, thus decreasing the collisions and decreasing pressure.
2. A has a higher pressure given that the higher the n value, or moles present, the higher the pressure will be if everything else is held constant.
3. Gases have weaker intermolecular forces than liquids and solids.
4. Pressure must be 1/2, or 0.5 as PV=k, (P)(4)=(2), (P)=(2/4)
5. 2.25 L
6. Increasing space will decrease collisions and vice versa
7. 1122 2L bottles
8. 2.35 L
9. 2.1428 L
10. It would expand as they are directly proportional
11. 2.14959 L
12. 546K
13. .003663 atm`K
14. If pressure and temperature are directly proportional, then they increase or decrease at a constant rate
15. quadruples as they are directly proportional
16. 18.9963587 atm
Sorry hun, I gotta go. Good luck!
Phosphorus can be prepared from calcium phosphate by the following reaction:

Phosphorite is a mineral that contains
plus other non-phosphorus-containing compounds. What is the maximum amount of
that can be produced from 2.3 kg of phosphorite if the phorphorite sample is 75%
by mass? Assume an excess of the other reactants.
Answer: Thus the maximum amount of
that can be produced is 0.345 kg
Explanation:
Given mass of phosphorite
= 2.3 kg
As given percentage of phosphorite
is = 



According to stoichiometry:
2 moles of phosphorite gives = 1 mole of 
Thus 5.56 moles of phosphorite give=
of 
Mass of 
Thus the maximum amount of
that can be produced is 0.345 kg
