Question

Please help and explain thanx
Methane (CH4), ammonia (NH3), and oxygen (O2) can react to form hydrogen cyanide (HCN) and water according to this equation:
CH4 + NH3 + O2  HCN + H2O
You have 8 g of methane and 10 g of ammonia in excess oxygen. Answer the following questions:
• What is the balanced equation for this reaction?
• Which reagent is limiting? Explain why.
• How many grams of hydrogen cyanide will be formed? Show your work.

Answer 1

The reaction isn't balanced, yet, because the number of each kind of atom on both sides are not equal. I like to make a table of all the atoms (not MOLECULES), and by adding coefficients to the fronts of the formulas you can change the number of atoms present until you have equal numbers on both sides.
