Answer:

The correct answer is option 4.

Explanation:

Substance which releases hydroxide ions(OH^-) in an aqueous solution are termed as bases.

Substance which releases proton (H^+) in an aqueous solution are termed as acids.

From the given options:

CH_3COOH : It is an weak organic acid known as acetic acid. Being acid it releases [H&+] ion in an aqueous solution.

CH_3COOH(aq)\rightarrow CH_3COO^-(aq)+H^+(aq)

CH_3COH : It is an alcohol named methanol and it is slightly acidic.They gives H^+ ions and alkoxiode ions.

CH_3COH(aq)\rightarrow CH_3CO^-(aq)+H^+(aq)

HCl : It is strong acid known as hydrochloric acid. Being highly acidic it releases [H&+] ion in an aqueous solution.

CH_3COOH(aq)\rightarrow Cl^-(aq)+H^+(aq)

KOH : It is strong base known as potassium hydroxide. Being highly acidic it releases [H&+] ion in an aqueous solution.

KOH(aq)\rightarrow K^+(aq)+OH^-(aq)

4- KOH

KOH is a strong base. In water it dissociates as 
<span>KOH--> K+ + OH- </span>
<span>A is acetic acid, a weak acid </span>
<span>CH3OH is an alcohol, weakly acidic in water </span>
<span>HCl is a strong acid.</span>

consider the following equilibrium:h2co3(aq) h2o(l) h3o (aq) hco3-1(aq).what is the correct equilibrium expression?
MAVERICK [17]

The equilibrium expression shows the ratio between products and reactants. This expression is equal to the concentration of the products raised to its coefficient divided by the concentration of the reactants raised to its coefficient. The correct equilibrium expression for the given reaction is:<span>

<span>H2CO3(aq) + H2O(l) = H3O+(aq) + HCO3-1(aq)

Kc = [HCO3-1] [H3O+] / [H2O] [H2CO3]</span></span>

Methane gas reacts with oxygen in a gas stove.
nekit [7.7K]

Hey there!

CH₄ + 2O₂ → CO₂ + 2H₂O

carbon dioxide: product

methane: reactant

oxygen: reactant

water: product

Methane and oxygen are reactants because they are the substances we start with. They are on the side of the equation that the arrow is pointing away from.

Carbon dioxide and water are products because they are the new substances  that are the yields of the equation. They are on the side of the equation that the arrow is pointing towards.

Hope this helps!
