The reaction of methane and oxygen yields carbon dioxide gas and water. The unbalanced reaction is as follows: CH4(g) + O2(g)CO2(g) + H2O(g)
A. If 1.26 grams of methane are reacted, how many grams of water vapor are produced?
B. If 2.796 grams CO2 are released, how many grams of methane were reacted?
1. Balance the equation.
2. Convert 1.26 g CH4 to moles. mols = grams/molar mass.
3. Using the coefficients in the balanced equation, convert moles CH4 to moles H2O.
4. Convert moles H2O to grams H2O. grams = mols x molar mass.
B is done the same way.
Post your work if you get stuck.
I don,t know about question.!!!!
