Answer:
1. Pressure increases
2. Volume increases
Explanation:
1. According to Gay-Lussac's law, at constant volume, the ratio of temperature and pressure is constant or they are directly proportional which essentially means if one increases or decreases, the other will too.
2. According to Charles' law, the volume is directly proportional to the temperature at constant pressure.

The molarity of H2SO4 is the number of moles in 1 L of solution.
The molarity is 2.0 mol/L
This means that there should be 2 moles in a 1 L solution to make up this molarity.
In this case we need to make up a 5 L solutions with that molarity. Then the amount of moles required are - 2 mol/L x 5 L = 10 mol
The correct answer is option C. Solutions that have more OH– than H+ ions are bases. These are substances that are slippery to touch and has an astringent taste. It reacts with acids in a neutralization reaction forming salts. It accepts protons. Examples are sodium hydroxide and potassium hydroxide.
