Why does ammonia act like a base?
(select those that apply)
it combines with h+ions.
ammonia releases oh-ions.
it increases the oh-concentration.
it dissociates easily.

It combines with H+ions.

Explanation: It combines with H+ions.

Ammonia releases ions.

According to Arrhenius concept, a base is defined as a substance which donates hydroxide ions when dissolved in water and an acid is defined as a substance which donates hydronium ions in water.

According to the Bronsted Lowry conjugate acid-base theory, an acid is defined as a substance which donates protons and a base is defined as a substance which accepts protons.

According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.

Ammonia being a lewis base donates lone pair of electrons and thus combines with . Also aqueous solution of ammonia gives ions in water, thus act as Arrhenius base.

possibly, yes.

explanation:

the amount of sugar you take in is dangerously high, risk of heart disease, high risk of diabetes, and etc.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
