Answer:
6 mols H2 are needed
Explanation:
N2 = 28.01g/mol
H2 = 2.02g/mol
*
= 6 mol H2
Explanation:
As the given data is as follows.
Height, H = 150 feet
Heat gain = 30,000 BTU/hr, and Heat loss = 25000 BTU/hr
m = mass of water heated = 700 gallons = 5810 lbs
is the heat capacity of water = 1 BTU/lb
(given)
= temperature difference =
Heat energy required to heat 700 gal can be calculated as follows:
Heat Required =
Thus, water rises till .
