Answer:
Four.
Explanation:
Hello!
In this case, according to the given chemical reaction:
Thus, since the reactants side (left) has three hydrogens in ammonia and one hydrogen in hydrochloric acid, we infer it has four hydrogen atoms at this side. Moreover, products side (right) has 4 hydrogen atoms as well, which means that the law of mass action is respected.
Best regards!
9.17 milliliters (mL) of the acid are needed to completely neutralize the base in this reaction.
<h3>What is a neutralization reaction</h3>A neutralization reaction is a reaction between an acid and a base to produce a salt and water only.
The process of reacting given volume of acids or bases to determine the concentration or volume of either the acid or base required for neutralization is known as titration in volumetric analysis.
The formula to determine the volume of the acid required is given below:
where is the volume of acid required
Concentration of base, Cb = (3.51/74)/0.75 = 0.063 M
Vb = 50. 0 mL
Ca = 0.229 M
Na = 2
Nb = 3
Va = (0.063 * 50 * 2)/(0.229 * 3)
Va = 9.17 mL
In conclusion, the volume of the acid is determined from the concentration, volume and mole ratio of the reaction.
