Enter the coefficients directly from the balanced chemical equation. do not reduce to lowest terms. for example: if 3 moles h2 react with 3 moles o2, enter "3" for each, not "1".

according to the following reaction:

ca(oh)2(aq) + 2hcl(aq) -> cacl2(aq) + 2h20(l)

what would you multiply "moles of calcium hydroxide" by to convert the units of "moles of water"?

moles ca(oh)2. (number)(unit) ÷ (number) (unit) = moles h2o

The coefficients are 2 for H₂O and 1 for Ca(OH)₂.

Explanation:

Let's consider the following reaction.

Ca(OH)₂(aq) + 2 HCl(aq) → CaCl₂(aq) + 2 H₂O(l)

According to the balanced equation, the molar ratio of H₂O to Ca(OH)₂ is 2:1. Using this conversion factor, we have the following proportion:

moles Ca(OH)₂. (2 mol H₂O ÷ 1 mol Ca(OH)₂) = moles H₂O

no but i do not usually comment or use my voice that much when it comes to social media

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons
