Answer 1

Answer #1

To write the balanced equation we have to keep in mind that the equivalent species on the both sides must have same number of molecules.

The answers i.e, the balanced equations are given as follows.

44. (B) 2 Mg + 2 CO2 + O2 $\rightarrow$ 2 MgCO 3

45. (E) None of these.

46. (C) Co(NH3)6Cl2 $\rightarrow$ CoCl2 + 6 NH3

47. (C) C12 H22 O11 $\rightarrow$ 12 C + 11 H2O
