Solid sodium bicarbonate is added to a solution of hydrochloric acid creating carbon

1 answer:

8 0

The balanced molecular equation for the reaction between solid sodium bicarbonate and hydrochloric acid to produce carbon dioxide gas, water and aqueous solution of sodium chloride is

<h3>NaHCO₃(s) + HCl(aq) —> CO₂(g) + H₂O(l) + NaCl(aq) </h3>

The balanced equation can be written as follow:

Sodium bicarbonate => NaHCO₃

Hydrochloric acid => HCl

Carbon dioxide => CO₂

Water => H₂O

Sodium chloride => NaCl

Sodium bicarbonate + Hydrochloric acid —> Carbon dioxide + Water + Sodium chloride

<h3>NaHCO₃(s) + HCl(aq) —> CO₂(g) + H₂O(l) + NaCl(aq) </h3>

The equation above is balanced since the number of the different atoms of the elements present on both sides are equal.

Thomas had a volume of 8.5 g of sodium chloride. What is the molar mass.?

alina1380 [7]

Answer:

58.44 g/mol

Explanation:

In this problem, make sure to remember that volume is measured in mL, L or any other units of volume. Remember that g represents grams, and grams is a measure of mass.

However, independent of what mass or what volume we take, molar mass is known to be an intensive property. That is, molar mass doesn't depend on any external conditions or any measurements.

Molar mass solely depends on the chemical structure of a compound and is a constant number at any given conditions.

In this problem, we are given sodium chloride, NaCl. In order to find its molar mass, we need to refer to the periodic table, find the atomic masses of Na and Cl and then add them up to have the molar mass of NaCl:

$M_{NaCl} = M_{Na} + M_{Cl} = 22.99 g/mol + 35.453 g/mol = 58.44 g/mol$
