When a hydrochloric acid solution is combined with a potassium hydroxide solution, an acid-base reaction occurs Write a balanced
Svetach [21]

Answer:

HCl(aq) + KOH(aq) ⇒ KCl(aq) + H₂O(l)

Explanation:

Hydrochloric acid is an acid because it releases H⁺ in an aqueous solution.

Potassium hydroxide is a base because it releases OH⁻ in an aqueous solution.

When an acid reacts with a base they form a salt and water. This is a neutralization reaction. The neutralization reaction between hydrochloric acid and potassium hydroxide is:

HCl(aq) + KOH(aq) ⇒ KCl(aq) + H₂O(l)

Consider the chemical equation in equilibrium.
djverab [1.8K]

Answer:

The forward reaction will be favored.

Explanation:

The reaction is:

2H_{2}(g)+2O_{2}(g)--->2H_{2}O(g)

As per equation (equilibrium equation), there are two moles of gaseous molecules on product side and three moles of reactant side.

a) If we increase pressure, the volume will decrease.

b) Due to decrease in volume, the moles per unit volume will increase.

c) In order to attain equilibrium again, the system will shift in the direction where it can nullify this effect [Le Chatelier's principle]

d) This can be done, if system moves in the direction where number of moles of gaseous molecules are less, which is product side.

e) Thus forward reaction will be favored.
