Charcoal is primarily carbon. what mass of co2 is produced if you burn enough carbon (in the form of charcoal) to produce 4.60kj×102kj of heat? the balanced chemical equation is as follows: c(s)+o2(g)→co2(g),δh∘rxn=−393.5kj

1) Balanced chemical equation:

C(s)+O2(g)→CO2(g), δh∘rxn=−393.5kj

2) Meaning: When burned 1 mol of C(s), this is solid pure charcoal, produces 1 mol of CO2 and liberates 393.5 kJ of heat

Ratio: 1 mol CO2 : 393.5 kJ

3) Proportion:

1 mol CO2               x
=
393.5 kJ          4.6 * 10^2 kJ

4) Solve for x:

x = 460 kJ * 1 mol CO2 / 393.5 kJ = 1.1690 mol CO2

5) convert moles to grams

mass in grams = number of moles * molar mass

mass in grams = 1.1690 mol * 44.01 g / mol = 51.4 g

51.4 g

You use the atomic number to find out how many protons and neutrons there are in the atom. you use the atomic mass to find out how many protons and electrons there are in the atom. 

Sorry i dont understand the question can you rephase it?
