To determine the amount of heat released upon complete combustion of 1 mol of methane, we simply multiply the heat of combustion of methane with the mass of methane. In this case, first, we need the molar mass of methane to convert the moles of methane given to grams of methane. We then have the following equation:
1 mol CH₄ x 16.0425 g/ mol CH₄ x 50.1 kJ/ g CH₄ = 803.73 kJ
Thus, the heat generated upon complete combustion of 1 mol of CH₄ is 803.73 kJ
Answer:
90 neutrons
Explanation:
#neutrons = Atomic Mass - Atomic Number
= 170 - 80 = 90 neutrons
