1. A piece of solid silver is placed into a solution containing nickel (II) ions. Write the balanced chemical equation for the reaction that produces solid nickel and silver ions. Predict whether the reaction is spontaneous. please explain your predictions.

2.A student chemist prepared several solutions to use in a chemical analysis, as outlined below. Each of the solutions was stored in a different type of container.

-Iron (II) nitrate in an aluminum flask

-Nickel (II) sulfate in a copper flask

-Magnesium nitrate in a copper flask

-Copper (II) sulfate in an iron drum

Predict whether the student will notice any changes a day later. Please explain your reasoning

For each solution that you will predict will react, what evidence of change do you think the student will observe? What would the balanced equation be for each predicted reaction?
