Question

Prove that law of conservation of mass when the mass of
BaCl2=20.8g,Na2So4=14.2g,BaSo4=23.3g and Nacl=11.7g in a chemical reaction.

Answer 1

Also lack of food production can result in high demand of that particular foodwhich would ultimately result in thehigh prices and scarcity of the food. The proper management of foodresults in safe, healthy and nutritiousproduction of food .it is necessary forincreasing shelf life of food

Answer 2

Bacl2+Na2SO4----->BaSO4+2NaCl

so,

R.H.S, 20.8+14.2=35.0

L.H.S, 23.3+11.7=approx 35

it  proves law of conservation of mass.
