Unit 2 Test Practice For each reaction, predict the chemical formula of the products (include notation for solid, liquid, gas or aqueous solution), state the type of each reaction and write a balanced chemical equation. If the reaction will not proceed, write NO REACTION (no need to balance the equation). 1. 2. 3. 4. 5. 6. 7. 8. Iodine is placed in aqueous potassium chloride Zinc is reacted with aqueous copper (II) nitrate. Aqueous magnesium bromide is reacted with hydrochloric acid. Phosphorous acid is neutralized by lithium hydroxide. Lead (IV) carbonate is decomposed by heat to test the law of conservation of mass . Stannic nitrate is added to a small amount of solution containing sodium sulfite. Pure methane gas completely burns in a Bunsen burner. Aluminum oxide reacts with water in the soil.
