Law which states that electric charges can neither be created nor be destroyed

Law of conservation of _____ states that matter can neither be created nor destroyed. [energy/mass]

Scientist who proposed that atoms can neither be created nor destroyed.

Statement-I : Law of conservation of mass hold good for nuclear reaction. Because Statement-II : Law states that mass can be neither created nor destroyed in a chemical reaction.

It states that matter can neither be created nor destroyed. This law was put forth by Antoine Lavoisier in 1789 . He performed rections for reaching to the above conclusion. This law formed the for several later developments in chemistry . Infact , this was the result of exact measurement of masses of reactants and products, and carefully planned experiments performed by Lavoisier 6.3 g of sodium bicarbonate is added to 15 g acetic acid solution . CO_(2) formed is allowed to escape. The weight of the solution left is 18 gram . What is the mass of CO_(2) formed.

Infact , this was the result of exact measurement of masses of reactants and products, and carefully planned experiments performed by Lavoisier. What weight of silver nitrate will react with 0.585 g NaCl to produce 1.435 g AgCl and 0.85 g NaNO_(3)

Correct the statement : Gases can neither be compressed nor be expanded.

Assertion: Matter can neither be created nor be destroyed. Reason : This is law of definite proportions.

STATEMENT -1 : In any chemical reaction, total No. of molecules are conserved. and STATEMENT -2 : Atom can neither be created nor be destroyed.

Energy can neither be created nor be .............. (produced/destroyed).

Assertion: Energy can neither be created nor destroyed. Reason: The principle of conservation of energy cannot be proved.
