<u>Answer:</u> The balanced chemical equation is written below.
<u>Explanation:</u>
Double displacement reaction is defined as the reaction in which exchange of ions takes place.
The chemical equation for the reaction of hydrochloric acid and potassium sulfide follows:
By Stoichiometry of the reaction:
2 moles of hydrochloric acid reacts with 1 mole of potassium sulfide to produce 2 moles of potassium chloride and 1 mole of hydrogen sulfide gas
Hence, the balanced chemical equation is written above.
Answer:
grams of solution = 551.98 g
Explanation:
Given data:
Percentage of solution = 32.9
Mass of solute = 181.6 g
Grams of solvent = ?
Solution:
Formula:
% = [grams of solute / grams of solution] × 100
Now we will put the values in formula.
32.9 = [ 181.6 g / grams of solution] × 100
grams of solution = 181.6 g × 100 / 32.9
grams of solution = 18160 g /32.9
grams of solution = 551.98 g
