copper sulphate react with sodium hydroxide to form a blue precipitate

1.	copper sulphate react with sodium hydroxide to form a blue precipitate of copper hydroxide and sodium sulphate .in an experiment ,15.95g of copper sulphate reacted with 8.0g of sodium hydroxide to form 9.75g of copper hydroxide and 14.2g of sodium sulphate .which law of chemical combination is illustrated by this data ? give reasons for your choice
Answer» tion:since the MASS of REACTANTS is equal to the mass of PRODUCTS. i.e. (15.95+8)=(14.2+9.75)=23.95gThe data represent the Law of CONSERVATION of mass in a chemical reaction.
