MEDIUMMCQ SINGLENEET ChemistryPhysical ChemistryMole _ Equivalent ConceptAtomic Theory Which of the following reaction is not according to the law of conservation of mass
A.2Mg(s) + O₂(g) → 2MgO(s)
B.C₃H₈(g) + O₂(g) → CO₂(g) + H₂O(g)✓ Correct
C.P₄(s) + 5O₂(g) → P₄O₁₀(s)
D.CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O
Explanation
Number of atoms in the reactant side is not equal to the number of atoms in the product side. Hence, (b) is not a correct reaction.
