Given the reaction below, how many grams of ClNO₂ can be made from 45.2 g of N₂O₄?

N₂O₄ + Cl₂ ---------> 2 ClNO₂

Acetylene, C₂H₂, can be used to prepare cyclopentadienone, C₅H₄O, using a catalyst. The reaction is:

2 C₂H₂ + CO -------> C₅H₄O

How many grams of acetylene are needed to prepare 150 g of cyclopentdienone?

240 ml of a 3.48 M solution of HCl Is poured onto solid Na₂CO₃. The resulting reaction is:

Na₂CO₃ + 2 HCl -------> CO₂ + H₂O + 2 NaCl

How many grams of CO₂ will be liberated by the reaction?

If 38.0 ml of a 0.250 M solution of AgNO₃ is mixed with 100 ml of a 0.059 M solution of Na₂S. The equation for the resulting reaction is:

Na₂S + 2 AgNO₃ --------> Ag₂S + 2 NaNO₃

How many grams of Ag₂S will be formed?

How many grams of NaOH would be necessary to completely neutralize a 55.0 gal drum of 0.250 M phosphoric acid?
