Find AS for the reaction between nitrogen gas and hydrogen gas to form ammonia. 1/2 N₂(g) + 3H₂(g) →NH3(g) You will need to look up values in the textbook (do not use the internet). If you don't have the textbook, check one out from library reserves.

Given that tin is higher than copper on the activity series of metals, write the one & only possible balanced chemical equation for a redox single replacement reaction that should take place in a reaction between TWO of the following substances: Sn(s); Cu(s); Sn(NO3)2; CuCl2(aq). Also: A solid forms in the reaction. What do you think or what is the solid?

Part IV Cabbage Juice Indicator Chop cabbage into small pieces until you have about 2 cups of chopped cabbage. Boil for at least ten minutes to allow time for the color to leach out of the cabbage. Allow it to cool for 15 min • Filter out the plant material to obtain a red-purple-bluish colored liquid. 1. Add 1-2 drops of cabbage juice into a small bowl 2. Add 3-5 drops of vinegar into the bowl with the cabbage juice 3. Observe Is this a chemical change or physical change? Explain? Store the excess cabbage juice in your refrigerator, you will need them for future experiments.

When magnesium metal is added to a beaker of HCl(aq), a gas is produced. Knowing that magnesium is oxidized and that hydrogen is reduced, write the balanced net equation for the reaction. (Use the lowest possible coefficients. Include states-of-matter under the given conditions in your answer.) Help chemPad XXº → Greek How many electrons are transferred in the balanced equation? What quantity of useful work can be obtained when Mg is added directly to the beaker of HCI? kJ How can you harness this reaction to do useful work? This is accomplished by making ---Select--- produce a voltage. cell that ---Select--- the reduction reaction and the oxidation reaction in order to control the flow of ---Select--- through a wire to
