Determine the mass of co2 produced by burning enough of methane to produce 1.50×102kj of heat. ch4(g)+2o2(g)→co2(g)+2h2o(g)δh∘rxn= −802.3kj express your answer using three significant figures.

The mass of produced will be 8.228 g.

Explanation:

We need to find the mass of carbon dioxide produced when 150 kJ of heat is released.

For the given chemical reaction:

By Stoichiometry of the reaction:

802.3 kJ of energy is released when 1 mole of carbon dioxide is produced.

So, 150 kJ of energy will be release when = of carbon dioxide is produced.

To calculate the mass of carbon dioxide, we use the equation:

Moles of carbon dioxide gas = 0.187 mol

Molar mass of carbon dioxide gas = 44 g/mol

Putting values in above equation, we get:

Hence, the mass of produced will be 8.228 g.
