Answer this , that would be very . 1. __ cao + __ h2o __ ca(oh)2 2. __ zn + __ hcl __ zncl2 + __ h2

Hey, for #1, it's 1, 1, 1 because it's already balanced!

For #2, it's 1, 2, 1, 1 since the product side has 2 Cl's but left side only had 1.

The first one is balanced so you do not have to worry about the coefficients in front of the elements. on the second one, add a 2 in front of the HCl on the left side and you will be balanced. have a great day! :)

1. Increase volume.

2. No change.

3. No change.

Explanation:

Hello,

In this case, if we want to shift the reaction rightwards, based on the Le Chatelier's principle we would have to:

1. For this reaction:

- Increase the volume or decrease the pressure, since there are more gaseous moles at the products.

2. For this reaction:

- Do nothing since it is not possible to achieve it as we have the same number of gaseous moles at both reactants and products.

3. For this reaction:

- Do nothing since it is not possible to achieve it as we have the same number of gaseous moles at both reactants and products.

Regards.
