1.	Which of the following reactions is not correct according to the law of conservation of mass ?
Answer» `2 Mg_((s)) + O_(2(g)) rarr 2MgO_((s))` `C_(3)H_(8(g)) +O_(2(g)) rarr CO_(2(g)) + H_(2)O_((g))` `P_(4(s))+5O_(2(g)) rarr P_(4)O_(10(s))` ` CH_(4(g))+2O_(2(g)) rarr CO_(2(g))+2H_(2)O_((g))` Solution :In this following equation, `{:(C_(3)H_(8(g)),+,O_(2(g)),rarr,CO_(2(g)),+,H_(2)O_((g))),(44g,,32G,,44g,,18g):}` The mass of REACTANTS `!=` mass of product Hence, LAW of CONSERVATION of mass is not followed.
