To answer this question, we will use pressure law which states that:
"At constant volume of a fixed mass of gas, the pressure of the gas is directly proportional to the temperature"
This means that:
Pi / Ti = Pf / Tf where:
Pi is the initial pressure = 1 atm
Ti is the initial temperature = 100 + 273 = 373 degree kelvin
Pf is the final pressure that we want to calculate
Tf is the final temperature = 139 + 273 = 412 degree kelvin
Substitute in the equation with the givens to calculate the pressure as follows:
1 / 373 = Pf / 412
Pf = (1/373) * 412 = 1.104557641 atm
Yes that is true, when energy is transformed energy is not destroyed.
The balanced reaction between Hydrogen and Oxygen to form Water:
2H₂ + O₂ → 2H₂O
From the equation it already states that:
2 molecules of Hydrogen H₂ are needed to produce 2 molecules of Water H₂O
So the answer is 2.
Option B.
Ok thanks for the valuble info.
