Atomic mass of reactants should be equal to the ……………… of products.

Mass of products is equal to mass of reactants.

If mass of apparatus is kept constant, mass of reactants is not equal to products.

We know that balancing of a chemical equation is entirely bases on law of conservation of mass. However the concept of Principle of Atom Conservation (POAC) can also be related to law of consevation of mass in a chemical reaction. So, POAC can also act as a technique for balancing a chemical equation. For example, for a reaction: ABC_(3) rarr AB+C_(2) On applying POAC for A , B and C and related the equations , we get : (n_(ABC_(3)))/(2) =(n_(AB))/(2) =(n_(C_(2)))/(3) ( n_(x) : number of moles of X) Thus , the cofficients of ABC_(3) , AB and C_(2) in the balanced chemical equation will be 2,2 and 3 respectively and the balanced chemical equation can be represented as , 2ABC_(3) rarr 2AB + 3C_(2) Which of the following statements jis correct balanced chemical equation, pA+qB_(2) rarr rA_(2)B_(5)

The law of conservation of mass states that mass is created during a chemical reaction.

Law of conservation of mass: When 4.2 g of sodioum hydrogen carbone (NaHCO_(3)) is added to a solution of acertc aacid (CH_(3) COOH) weighting 10.0 g then 2.2 g of carbon diosxed (CO_(2)) is released into the atmosphere and the residue ledft weighs 12.0 g . Show that these observation are in agreement with the law of conservation of mass. Strategy: Find the sum total of mass of recants before the reaction and sum total of mass of products after the reaction.

Define the law of conservation of mass. How is it applicable to chemical reactions?

Statement-I : A reactant that is entirely consumed when a reaction goes to completion is known as limiting reactant. Because Statement-II : The amount of reactant limits the amount of product formed.

In exoergic reaction, the total mass of products is ……………………….. than the total mass of reactants.
