Write down the equations for the reactions of nitric acid with: zinc zinc oxide zinc hydroxide zinc carbonate Draw up electronic balance schemes for the equations of redox reactions and ionic equations for ion exchange reactions.

1. The reaction of nitric acid and zinc is redox, as it proceeds with a change in the oxidation states of zinc (from zero to +2) and nitrogen (from +5 to +4).

Let’s arrange the coefficients using the electronic balance method.

1. We write out the elements that have changed the oxidation state, we find the number of electrons donated or received. To do this, subtract the final

Zinc gives up 2 electrons, is a reducing agent, and is itself oxidized.

Nitrogen accepts 1 electron, is an oxidizing agent, and is reduced.

We find the common multiple for the found number of electrons (this is 2), we divide accordingly by this number of electrons. Thus, we have found the coefficients that need to be placed in front of the formulas. First, we arrange on the right side of the equation (equalize zinc, nitrogen), and then on the left side. Last but not least, we balance the oxygen.

2) The equations between zinc oxide, zinc hydroxide and zinc carbonate are ionic, proceed in the formation of zinc nitrate and water.
