Write and balance the following word equations
nitrogen + hydrogen = ammonia ( NH3)
Barium chloride + magnesiun sulfate =barium sulfate + magnesium chloride

Write and balance the following word equations
nitrogen + hydrogen = ammonia ( NH3)
Barium chloride + magnesiun sulfate =barium sulfate + magnesium chloride



Well, basically when you have to write and balance equations , you have to know the chemical symbols for all elements involved and whether they occur as monoatomic (with only one atom) or diatomic (with 2 atoms) elements.

Nitrogen + Hydrogen = Ammonia


N2 + H2 - > Nh3

To balance this , you need to first balance any one element in the equation ,ensuring both sides have equal number of the same elements. In this case , you should balance the hydrogen first:


N2 + 3H2 - > 2NH3


You will notice that:
N2 = 2N
3H2 = 2H3

and therefore the equation is balanced.


Try the next one yourself. Just remember to break everything down and once you get the hang of it, it will be simple.

iron + sulfur = ferrous sulfide
