Explanation:
A chemical equation is a equation that describes a corresponding chemical reaction.
A chemical reaction is generally written as
→
refer to all the reactants involved in the chemical reaction.
Reactants are usually written on the left hand side of the chemical equation.
refer to all the products formed in the chemical reaction.
products are usually written on the right hand side of the chemical equation.
In the given reaction,,
are written on the right side of the equation.
So,,
are the products.
Answer:
-5.51 kJ/mol
Explanation:
Step 1: Calculate the heat required to heat the water.
We use the following expression.
where,
The average density of water is 1 g/mL, so 75.0 mL ≅ 75.0 g.
Step 2: Calculate the heat released by the methane
According to the law of conservation of energy, the sum of the heat released by the combustion of methane (Qc) and the heat absorbed by the water (Qw) is zero
Qc + Qw = 0
Qc = -Qw = -22.0 kJ
Step 3: Calculate the molar heat of combustion of methane.
The molar mass of methane is 16.04 g/mol. We use this data to find the molar heat of combustion of methane, considering that 22.0 kJ are released by the combustion of 64.00 g of methane.
