Magnesium forms magnesium oxide when reacts with oxygen present in air. On the magnesium ribbon a stable layer of magnesium oxide is formed when it is stored, which prevents the further reaction of magnesium ribbon. Hence, to clean up the layer of magnesium oxide, magnesium ribbon is cleaned beforeRead more
Magnesium forms magnesium oxide when reacts with oxygen present in air. On the magnesium ribbon a stable layer of magnesium oxide is formed when it is stored, which prevents the further reaction of magnesium ribbon. Hence, to clean up the layer of magnesium oxide, magnesium ribbon is cleaned before burning.
Write the balanced equation for the following chemical reactions.
(i) H2+CL2→2HCl (ii) 3BaCl2+Al2(SO4)3→3BaSO4+2AlCl3 (iii) 2Na+2H2O→2NaOH+H2
(i) H2+CL2→2HCl
