Explanation:
cl2 = 50/71
mole of cl2 = 0.704
no.of molecules = mole × avagadro no.
no of molecules = 0.704× 6.022×10²³
no. of molecules = 4.23×10²³

<u>mass of reactants = mass of products</u> best represents the law of conservation of mass
Explanation:
This is a law of thermodynamic that applies to chemical reactions. The mass of the reactants must equal to that of the products because energy/mass cannot be destroyed or created. This is why ideally, chemical reactions should be balanced to conform to this law.
