More water is not always better. For example; cacti only need water about every two weeks, the same with succulent plants. Not every plant needs to be watered every day, or the plant may be overwatered and die.

Answer:
0.89 atm is the pressure of the hydrogen gas
Explanation:
We can use the molar fractions to solve this
Sum of molar fractions (hydrogen + water vapor) = 1
Molar fraction = Pressure gas / Total pressure
Molar fraction water vapor = 0.13 atm/1.02 atm = 0.127
1 - 0.127 = 0.873 (Molar fraction H2)
0.873 = Pressure H2 / Total pressure
0.873 = Pressure H2 / 1.02 atm
0.873 . 1.02atm = 0.89 atm
Matter is anything that has mass and takes up space.
