Question

Determine the atom inventory for the following equation: 3Mg + 3O2 arrow 3MgO. Does this equation follow the law of conservation of mass?

Mg = 3, O = 6; Mg = 3, O = 6; yes, this equation follows the law of conservation of mass

Mg = 3, O = 5; Mg = 3, O = 1; no, this equation does not follow the law of conservation of mass

Mg = 3, O = 6; Mg = 3, O = 3; no, this equation does not follow the law of conservation of mass

Mg = 3, O = 1; Mg = 3, O = 1; yes, this equation follows the law of conservation of mass
