a) If 50.0g of Ca(OCl)2 and 275mL of 6.00M HCL are allowed to react, how many grams of chlorine gas will form?

b) Which reactant will be in excess and what is its mass?

**The attempt at a solution**

Ca(ClO)2 + 4 HCl → CaCl2 + 2 H2O + 2 Cl2 is this a redox equation ? i don't know how to proceed. Any help would be would be appreciated ...
