4. copper metal reacts with nitric acid(hno3) to produce aqueous copper (ii)nitrate, nitrogen dioxide gas and liquid water. a. write the balanced equation for the reaction b. if there are 0.500 moles of copper metal present how many moles of nitric acid are required for the reaction? how many moles of nitrogen dioxide gas are formed?

a.

b.

Explanation:

a. For the balanced equation we have to obtain the same amount of atoms in both sides:

b. If we want to calculate the moles of nitric acid we have to use the molar ratio in the balence reaction:

For the moles of nitrogen dioxide we have to follow the same logic:
