<u>Answer:</u> The mass of Na_2SO_4 produced will be 17.8 grams.

<u>Explanation:</u>

To calculate the number of moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}  ....(1)

<u>For Sodium hydroxide:</u>

Given mass of sodium hydroxide = 10 g

Molar mass of NaOH=[(1\times 22.989)+(1\times 15.999)+(1\times 1.008)]g/mol=39.996g/mol

Putting values in above equation, we get:  

\text{Moles of sodium hydroxide}=\frac{10g}{39.996g/mol}=0.25mol

For the given chemical equation:

2NaOH+H_2SO_4\rightarrow Na_2SO_4+2H_2O

By Stoichiometry of the reaction:

2 moles of sodium hydroxide produces 1 mole of sodium sulfate.

So, 0.25 moles of sodium hydroxide will produce = \frac{1}{2}\times 0.25=0.125moles of sodium sulfate.

Now, to calculate the mass of sodium sulfate, we use equation 1:

Moles of sodium sulfate = 0.125 moles

Molar mass of Na_2SO_4=[(2\times 22.989)+(1\times 32.065)+(4\times 15.999)]g/mol=142.039g/mol

Putting values in equation 1, we get:

0.125mol=\frac{\text{Mass of }Na_2SO_4}{142.039g/mol}\\\\\text{Moles of }Na_2SO_4=17.8g

Hence, the mass of Na_2SO_4 produced will be 17.8 grams.

Answer:

They are a base and an acid,  so they neutralize each other.

Explanation:

Sodium hydroxide is a strong base. Hydrochloric acid is a strong acid.

They react with (neutralize) each other to form a salt (sodium chloride) and water.

NaOH + HCl ⟶ NaCl + H₂O
