One slight problem. 174 molecules is not 174 moles. 174 molecules x (1 mol/6.02 x 10^23 molecules) = # mols CO2 produced if you want to go that way. Otherwise, the reasoning is sound; therefore, 174 molecules of water will be formed when 174 molecules of CO2 are formed.

An industrial chemist puts 1.00 mol each of H2(g) and CO2(g) in a 1.00-L container at 800oC. When equilibrium is established, 0.49 mol of CO(g) is in the container. Find Kc at 800 C for the following reaction: H2(g) + CO2(g) ⇌ H2O(g) + CO(g).

Balance this equation. NaHCO3(s) + heat ----> Na2CO3(s) + H2O(l) + CO2(g). i balanced it & got: 2NaHCO3(s)+ heat -->Na2CO3(s)+ H2O(g)+CO2(g) is this right ? Determine how many moles of CO2(g) is produced when 7mols of NaHCO3 are consumed. how do i do this ?

CH4 + 2O2 ==> CO2 + 2H2O 2C2H6 + 7O2 ==> 4CO2 + 6H2O I would look at this. Since we have all gases we need not convert to mols but we can use volume directly. Let x = volume CH4 and y = volume C2H6 --------------------- x + y = 24 cc which is equation 1. x cc of CH4 will...

Now say when your converting CO2 to moles carbon, do you multiply by (1 mole C/1 mole CO2)?

i have a hard time understanding how to calculate the moles of CO2 remaining? how do you use the PV=nRT for the remaining CO2?

Loss in mass = mass CO2 = 2.621g. mols CO2 = grams CO2/molar mass CO2. mols CaCO3 = mols CO2 (look at the balanced equation). CaCO3 ==> CaO + CO2. g CaCO3 = mols CaCO3 x molar mass CaCO3.
