Homework Answers
Valency of copper is generally 2 and copper is metal. So, ionic form of copper is Cu2+.
Valency of chlorine is 1 and chlorine is non-metal. So, ionic form of chlorine is Cl-.
From this, copper chloride will be CuCl2, mean 2 chlorine ions for each Cu2+ ions. Option C is correct.
Please give good rating.

The reaction of hypochlorite to form chloride and chlorate ions ( a disproportionation!!) in aqueous solution was followed by monitoring the concentration of chloride: 3 ClO-(aq) 2 Cl-(aq) + ClO3-(aq) If the chloride ion is produced at an instantaneous rate of 0.018 mol/L/s at a particular temperature, what is the rate of loss of the reactant, the hypochlorite ion? ( Answer to 2 significant figures and use e notation for powers of 10, e.g. 1.2e2 for 1.2 x 102)
