Answer:

The mass of 1.26 mole of water, H₂O, is 22.68 grams

Explanation:

Molar mass is the amount of mass that a substance contains in one mole. In other words, the molar mass of an atom or a molecule is the mass of one mole of that particle and its unit is g/mole.

In this case, being:

  • H: 1 g/mole
  • O: 16 g/mole

the molar mass of water H₂O is:

H₂O= 2*1 g/mole + 16 g/mole= 18 g/mole

Then you can apply the following rule of three: if 18 grams are present in 1 mole of H2O, how much mass is present in 1.26 moles of water?

mass=\frac{1.26 moles*18 grams}{1 mole}

mass= 22.68 grams

<u><em>The mass of 1.26 mole of water, H₂O, is 22.68 grams</em></u>

Which of the following is a correct balanced equation for the neutralization reaction that occurs
PtichkaEL [24]

Neutralization reaction takes place between an acid and a base to form salt and water.

In the given reaction the acid is hydrochloric acid HCl and the base is aluminum hydroxide (Al(OH)_{3}).

The correct balanced equation for the neutralization reaction that occurs between aluminum hydroxide and hydrochloric acid can be represented as:

Al(OH)_{3}(aq)+ 3HCl(aq) --->AlCl_{3}(aq)+3H_{2}O(l)

Al(OH)_{3}can give 3 hydroxide, OH^{-}ions which can neutralize the 3 H^{+}ion produced by 3 HCl molecules giving 3 mole of water and the salt aluminum chloride, AlCl_{3}.

Therefore the correct option will be.

D. Al(OH)3 + 3 HCl (aq) --> AlCl3(aq) + 3 H2O(l)
