Answer:
Faster hydrogen burning means the star will grow larger and more luminous to allow the extra energy created to escape
Answer:
0.91 atm is the partial pressure of just hydrogen gas.
Explanation:
Vapor pressure of water , p= 0.0313 atm
Partial pressure of hydrogen gas = 
Total pressure of the water vapors and hydrogen gas = P = 715 Torr
1 atm = 715 Torr

According Dalton's law of partial pressure:



0.91 atm is the partial pressure of just hydrogen gas.
When a bond is formed, energy is released into the environment. That is because it is an exothermic reaction, it releases energy. <span />
