Write out the balanced chemical equation for the double replacement reactionYou may be given either the number
of grams or moles of chemical A…
..and asked to determine either the
number of moles or grams of chemical B
Grams of A
Moles of A
Moles of B
Grams of B
1. Convert from the number of 2. Convert from the number 3. Convert from the number of
grams of A to the number of moles of moles of A to the number
of A using the molar mass of A.
moles of B to the number of grams
of moles of B using the
of B using the molar mass of B.
coefficients of the balanced
8. How many grams of H2 are required to produce 7.50 grams of ammonia NH3? Use the balanced
equation (this time the equation is already balanced):
N2(g) + 3H2(9) – 2NH3(9)
9. If 54.7 grams of propane (C3Hs) and 89.6 grams of oxygen (O2) are available in the balanced
combustion reaction below:
C3 H8 + 502 – 3CO2 + 4H20
a) Which reactant is limiting (show your work)?
b) What is the theoretical yield of CO2 in grams?
