Answer:
what is the valency of carbon in CH3-CH3,CH2=CH2AND HC=CH. The valency of carbon in all the given structures is fourplanation:
CaCO3=100g
CaO=56g
56g of CaO=100g of CaCO3
1.12g of CaO= 100/56*1.12 g of CaCO3
=2g of CaCO3 (ans)
Reactants are carbon dioxide and water, the products are glucose and oxygen. Don't know for sure what the yield is represented with, so, I can't help you with that.
