Question

Explain law of conservation of mass with an experiment

Answer 1

According to law of conservation of mass ,mass neither be created nor be destroy.

Experiment:-

H2+O2=H2O

Balancing the above equation

2H2+02=2H2

Mass of hydrogen +mass of oxygen =mass of H2O

4u+32u=2×18th

36u=36u

SO, mass of reactant =mass of product

If u like my answer than mark me as brainlist

Answer 2

According to that the mass cannot be created nor be destroyed in any chemical reaction.i.e the total mass of reactants = the total mass of the product. eg. sodium carbonate(4.0g) + hydrochloric acid(10.0g)➡ carbondioxide (2.5g) +sodium chloride (11.5)
here , total mass of reactants = 4.0+10 = 14g
total mass of product s= 2.5 +11.5= 14 g
