Which of the following data illustrates the law of conservation of mas

1.	Which of the following data illustrates the law of conservation of mass?a)56g of co reacts with 32g of oxygen to produce 44g of co2b) 1.70g of AGNO3 reacts with 100ml of 0.1 MHCL to produce 1.435g of Agcl and 0.63g of HNO3c)12g of C is heated in vaccum and on cooling there is no change in massD)none of these
Answer» Explanation: MASS of reactant = mass of product find moles of HCL and then weight of HCl mass is conserved so 2 OPTION is correct

Answer»

Explanation:

MASS of reactant = mass of product

find moles of HCL

and then weight of HCl

mass is conserved

so 2 OPTION is correct
