Answer : The steps for balancing a redox reaction using half reaction method will include the following steps :
1) Write the basic ionic form of the reaction equation.
2) Divide the equation into two separate half reaction which will have oxidation half and reduction half reactions.
3) Balance the atoms present in each half of the reactions except O and H atoms in the reaction.
4) Balance the oxygen atoms in the reduction half of the reaction by the addition of two water molecules in the given conditions of the reaction.
5) Balance the charges present in both the half reactions.
6) The two halves of the equations reduction and oxidation are added to complete the overall reactions. After the addition of two reaction halves, cancel the same number electrons on both sides. The net ionic equation can be written after this step.
7) Finally, Verify whether the equation consists of the same type, number of co-efficients, and charges on both sides of the equation.

I need help with this as well if you get the answer please let me know
Explanation:
Given:
Ammonia
Hydrochloric acid
To find:
The amount excess of reactant left over in ammonia.
Solution:
Ammonia reacts rapidly with hydrochloric acid to form Ammonium Chloride
Equation for the above statement is derived as:
One gram per mole of ammonia
Similarly for 6.91g of
One gram per mole of hydrochloric acid
Similarly for 4.61g of
From the above information we can say that h c l is a limiting reactant.
Limiting reactant is an element that consumes lesser product in a chemical reaction.
Thus the amount of excess reactant is calculated by using the following formula
Amount of excess reactant left over in
Result:
Amount of excess reactant left over ammonia
the answer is A......
it is supported by practical evidence and examples. this is the answer because he tried and tested many different ways to see what would happen so he is happy with the conclusion that what he tested is what he gets.
