In an accident, a solution containing 2.5 kg of nitric acid was spilled. Two kilograms of Na2CO3 was quickly spread on the area
storchak [24]

First we must write a balanced chemical equation for this reaction

Na_2CO_3 _(_a_q_)+ 2HNO_3_(_a_q_) \implies 2NaNO_3_(_s_) + CO_2_(_g_) + H_2O_(_l_)

The mole ratio for the reaction between HNO_3 and Na_2CO_3 is 1:2. This means 1 moles of Na_2CO_3 will neutralize 2 moles HNO_3. Now we find the moles of each reactant based on the mass and molar mass.

2500g HNO_3 \times \frac{mol}{63.01g\ HNO_3} = 39.67 mol\ HNO_3

2000g\ Na_2CO_3 \times \frac{mol}{105.99g \ Na_2CO_3} = 18.87 mol\ Na_2CO_3

\frac{18.87 mol Na_2CO_3}{39.67\ HNO_3} = \frac{1 molNa_2CO_3}{2 mol HNO_3}

The Na_2CO_3 was enough to neutralize the acid because 18.87:39.67 is the same as 1:2 mol ratio.

Why is it not correct/precise to say "a molecule of salt?"
Fynjy0 [20]

It is not correct to say " a molecule of salt " because salt is a compound.

Explanation:

  • As we know a molecular bond is present in each molecule.
  • Salt (NaCl) is considered as a compound because it is made up of two types of elements that are sodium as well as chlorine.
  • On the other hand it is not considered as a molecule as it is not holding an ionic bond.
  • As a result we can name it as an ionic compound. Hence it is not considered as a molecule of salt.
