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!

Answer:
An Mg atom donates one electron to each of the two Cl atoms.
Explanation:
Chlorine is a non-metal halogen and does not have the ability to donate electrons, on the contrary, it picks them up. In fact it is almost the most electronegative of the periodic table, below the fluoride that is the most.
The chlorine then accepts one electron per magnesium to form the magnesium chloride being its formula MgCl2.
Magnesium is a metal of group two and it does yield electrons, in this case it can only yield 2 (group 2 of the Periodic Table) forming the Mg 2+ cation
Mg2+ + 2Cl- ------> MgCl2
Answer:
im pretty sure the answer is number 3. The nervous system provides nutrients and oxygen for the muscular system
Explanation:
Radio waves. Microwaves would cook the earth, seismic waves would just cause earthquakes everywhere, and infrared waves would also cook the earth.
