When cobalt (III) carbonate is exposed to calcium metal a single displacement reaction takes place. This reaction causes the calcium to replace the cobalt, forming calcium carbonate. Cobalt metal is the other product of this reaction. Co2(CO3)3 + 3 Ca 3 CaCO3 + 2 Co
1. If 52.1g of Co2(CO3)3 reacts completely, how many grams of cobalt metal is produced?
2. If 23.8 g of calcium reacts completely, how many grams of CaCO3 are produced?
3. How many grams of calcium metal reacts completely with 31.4g of cobalt (III) carbonate?
4. If 15.3 g of calcium reacts completely with excess Co2(CO3)3, how many grams of cobalt are produced?
5. What mass of cobalt (III) carbonate will react to produce exactly 29.3 grams of cobalt metal?
A 22.8 gram sample of Al(NO2)3 reacts with excess Mg in a single-displacement reaction. What mass of Mg(NO2)2 is produced? 2 Al(NO2)3 + 3 Mg 3 Mg(NO2)2 + 2 Al
