15.9 of copper sulphate and 10.6 g of sodium carbonate react together to give 14.2 g of sodium sulphate and 12.3 g of copper carbonate . Which law of chemical combinations is obeyed ? How?

Text Solution

Verified by Experts

Reactants: Mass of copper sulphate=15.9 g: Mass of sodium carbonate=10.6 g Total mass of reactants =15.9 +10.6 =26.5 g
Products: Mass of sodium sulphate=14.2 g, Mass of copper carbonate=12.3 g `therefore` Total mass of reactants is equal to total mass of products. This is the "Law of conversation of Mass".
