A) The law of conservation of mass.
B) The law of constant composition.
C) The law of reciprocal proportion.
D) None of these
Correct Answer: A
Solution :
[a] \[\underset{20g}{\mathop{CaC{{O}_{3}}}}\,\to \underset{8.8g}{\mathop{CaO}}\,+\underset{11.2g}{\mathop{C{{O}_{2}}}}\,\] mass of reactant = mass of products = 20g. Hence the law of conservation of mass is obeyed.You need to login to perform this action.
