Balance the following chemical equation: MnO 2 + HCl → MnCl 2 + Cl 2 + H 2 O

Manganese dioxide reacts with hydrochloric acid and forms manganese chloride, chlorine gas and water. The balanced chemical equation is : MnO 2 s + 4 HCl aq → MnCl 2 s + Cl 2 g + 2 H 2 O l

Balance the following equation: NH 3 + CuO → Cu + N 2 + H 2 O

A balanced chemical is equation has equal numbers of atoms for each element involved in the reaction are represented on the reactant and product sides. Ammonia reacts with copper oxide and forms copper, nitrogen and water. The balanced chemical equation is: 2 NH 3 g + 3 CuO s → 3 Cu s + N 2 g + 3 H 2 O l

Balance the following equation: Al 2 ( SO 4 ) 3 + NaOH → Al ( OH ) 3 + Na 2 SO 4

Aluminium sulphate reacts with sodium hydroxide, and it forms aluminium hydroxide and sodium sulphate. The balanced chemical equation is: Al 2 ( SO 4 ) 3 s + 6 NaOH aq → 2 Al ( OH ) 3 aq + 3 Na 2 SO 4 aq
