Can you please help me with question 4.
1) Group 1 metals react almost instantly and violently with water, as a single replacement reaction to produce an aqueous solution of metal hydroxide and hydrogen gas. A sample of solid lithium weighing 84.25 mg is dropped into a beaker containing 50.0 mL of water. Assume the density of water is 0.9988 g/mL. a) Write the balanced equation. b) Calculate the theoretical yield (in grams) of lithium hydroxide. c) Assuming the reaction is complete, and that there is no volume change, what is the concentration (in M) of lithium hydroxide in the solution that results?

Choose a chemical reaction that is used in industry, research, or nature. DO NOT USE the photosynthesis process or the cellular respiration process. Photosynthesis and cellular respiration are not single chemical reactions; they are each a series of chemical reactions. For the reaction that you choose: 1) Write the balanced chemical equation for the reaction (include the phases). 2) What is/are the reactant(s)? 3) What is/are the product(s)? 4) Why is this reaction important in either industry, research, or nature?
