The correct option is B -i- and -iii-Magnesium burns in carbon dioxide because the oxygen in the carbon dioxide is able to bond with magnesium and produce an oxide-Hence-xA0-it keeps on burning-2Mg-s-CO2-g-x2192-2MgO-s-C-s-So the correct option is-xA0-i- and -iii-

The correct option is B (i) and (iii)Magnesium burns in carbon dioxide because the oxygen in the carbon dioxide is able to bond with magnesium and produce an oxide.Hence it keeps on burning.2Mg(s)+CO2(g)→2MgO(s)+C(s)So the correct option is (i) and (iii).

The correct option is B (i) and (iii)
Magnesium burns in carbon dioxide because the oxygen in the carbon dioxide is able to bond with magnesium and produce an oxide.
Hence it keeps on burning.
$2 M g (s) + C O_{2} (g) \to 2 M g O (s) + C (s)$
So the correct option is (i) and (iii).
