Question

How is this done I was given the wrong example

Answer 1

According to the explanation given in our previous session

8. N2 + 3 H2 -> 2 NH3

Reactants

N = 2

H = 6

Products

N = 2

H = 6

As we can see, both sides now have the same number of elements, 2 Nitrogens and 6 Hydrogens, this is what we need to do in a balancing reaction question

9. MgCl2 + 2 NaBr -> MgBr2 + 2 NaCl

Reactants

Mg = 1

Cl = 2

Na = 2

Br = 2

Products

Mg = 1

Cl = 2

Na = 2

Br = 2

Same number of elements on both sides
