Suppose hydrochloric acid reacts with potassium sulfite yielding water, sulfur dioxide, and potassium chloride. Suppose 4 moles

anzhelika [568]

Answer:

128 grams of sulfur dioxide are produced.

Explanation:

$2HCl+K_2SO_3\rightarrow SO_2+2KCl+H_2O$

Moles of HCl = 4 moles

According to reaction, 2 moles of HCl gives 1 mole of sulfur dioxide gas.

Then 4 moles of HCl will give:

$\frac{1}{2}\times 4 moles=2 moles$ of sulfur dioxide gas.

Mass of sulfur dioxide gas = 2 mol × 64 g/mol = 128 g

128 grams of sulfur dioxide are produced.
