Question

Balance the following equations. (Each 1 marks)
A N2 + H2 ------> NH3
B Al2O3 -------> Al + O2
C FeSO4 ------> Fe2O3 + SO2 + SO3
D ZnO + HNO3 ------->Zn(NO3)2. + H2O E Ca(OH)2 + NH4Cl ------> NH3 + CaCl2 + H2O​

Answer 1

Answer:

A) The new chemical equation is N2 +H2 →2 NH3 Reactants Products Nitrogen 2 2 Hydrogen 2 6 Since NH3 is multiplied by a coefficient of 2 there are now 2 nitrogens and 6 hydrogens. The 6 hydrogens come from the 2 multiplied by the subscript of 3.
