Answer: Sulfur dioxide is he gas formed in the chemical reaction below.

Explanation: The reaction between Acetic acid and Lithium hydrogen sulfite produces water, sulfur dioxide and lithium acetate. The balanced Chemical reaction is:

$HC_2H_3O_2(aq.)+LiHSO_3(aq.)\rightarrow H_2O(l)+SO_2(g)+LiC_2H_3O_2(aq.)$

The gas produced is sulfur dioxide when this reaction takes place.

Answer: 0.9375 g

Explanation:

To calculate the number of moles for given molarity, we use the equation:

$\text{Moles of solute}={\text{Molarity of the solution}}\times{\text{Volume of solution (in L)}}$ .....(1)

Molarity of $HCl$ solution = 0.75 M

Volume of $HCl$ solution = 25.0 mL = 0.025 L

Putting values in equation 1, we get:

$\text{Moles of} HCl={0.75}\times{0.025}=0.01875moles$

$CaCO_3(s)+2HCl(aq)\rightarrow CaCl_2(s)+CO_2(g)+H_2O(l)$

According to stoichiometry :

2 moles of $HCl$ require = 1 mole of $CaCO_3$

Thus 0.01875 moles of $HCl$ will require= $\frac{1}{2}\times 0.01875=0.009375moles$ of $CaCO_3$

Mass of $CaCO_3=moles\times {\text {Molar mass}}=0.009375moles\times 100g/mol=0.9375g$

Thus 0.9375 g of $CaCO_3$ is required to react with 25.0 ml of 0.75 M HCl
