Answer: The mass of and
produced are 336.6 g and 183.6 g respectively.
Explanation:
The combustion reaction between propane and oxygen leads to formation of carbon dioxide and water.
Law of Conservation of mass states that the mass will remain constant for a balanced equation. This is carried out when the total number of atoms on reactant side is same as the total number of atoms on the product side. Thus the equation must be balanced.
a) 1 mol of propane produces = 3 moles of
Thus 2.55 mol of propane produces =
mass of
b) 1 mol of propane produces = 4 moles of
Thus 2.55 mol of propane produces =
mass of
The mass of and
produced are 336.6 g and 183.6 g respectively.
Answer: 151 kJ
Explanation:
To calculate the moles :
It is given that:
0.267 moles of absorb energy = 40.3 kJ
Thus 1 mole of absorb energy =
Thus the value of for the chemical equation given is 151 kJ
