Answer:

BRAINLIEST?

Explanation:

Ammonia is a typical weak base. Ammonia itself obviously doesn't contain hydroxide ions, but it reacts with water to produce ammonium ions and hydroxide ions. My findings said that ammonia is a weak base, potassium hydroxide is a strong base, vinegar is a weak acid and ethyl alcohol is a weak acid.

Vinegar and ethyl alcohol are eliminated as they are acids. The question is on bases.... Potassium hydroxide is a strong base. So we are left with ammonia, being a weak base.

A is your answer

NH3 is a weak base and KOH is a strong base. A true statement about both of them is that; "A solution of potassium hydroxide will always have greater conductivity than a solution of ammonia."

The terms "strong base" and "weak base" both refer to the extent of ionization of a substance in solution.

A strong base ionizes completely in solution while a weak base ionizes partially in solution.

Since conductivity depends on the extent of ionization of a substance in solution, KOH which is strong base will always have a higher conductivity that NH3 since there are more ions in KOH solution than in NH3 solution.

Find the number of moles of water that can be formed if you have 182 mol of hydrogen gas and 86 mol of oxygen gas.

frutty [35]

Water has a chemical formula of H2O. This means that for every 2 moles of hydrogen and 1 mole of oxygen, one mole of water will be formed.

Note that hydrogen gas and oxygen gas are both biatomic molecules.

(1) (182 mol H2) x (1 mol H2O/ 1 mol H2) = 182 mol H2O
(2) (86 mol O2) x (2 mol H2O / 1 mol O2) = 172 mol H2O

We choose the smaller number of the two as the answer to this item. Thus, the answer to this question is 172 mol of H2O can be formed out of the given quantities.
