Description
2. How many grams of potassium Chlorite KCIO2 are needed to produce 12.8 g of potassium chloride KCI?
2 KCIO2 –> 3 02 + 2 KCI
3. What mass of metallic copper, Cu is nmeeded to produce 5.21 g of nitrogen monoxide NO using an excess of nitric acid?
3 Cu + 8 HNO3 —> 3 Cu(NO3)2 + 4 H20
4. How many grams of oxygen 02 are needed to react with 1.75 grams of phosphine PH3?
4 PH3 –> 8 02 —> P4010 + 6H20
5. What mass of silver (1) oxide is needed to produce 0.125 mols of metallic silver?
Ag20 —> Ag + _02
What is the theoretical yield of potassium chloride if 0.203 mol of chlorine C12 react completely with 0.300 mol of potassium bromide, KBr
