• Remember in an acid-base reaction, there is only the movement of a hydrogen atom from the acid to the base. • When writing the reaction, be sure to use the correct arrow. How do you know if you need a single arrow pointing toward products or an equilibrium arrow • Include the physical state of all reactants and products. 1. Write the reaction between an aqueous solution of HNO3 and water. Write the reaction using Lewis structures. 2. Write the reaction between an aqueous solution of CH3COOH and water. Write the reaction using Lewis structures. 3. Write the reaction between an aqueous solution of CH3NH2 and water. Write the reaction using Lewis structures. 4. Write the reaction between an aqueous solution of HCN and water. Write the reaction using Lewis structures.

Carbon monoxide and nitrogen monoxide react to produce carbon dioxide and nitrogen gas. If the system contains platinum, then less energy is required for the reaction to occur. Which term best describes the role of platinum in the system? catalyst product energy reactant

novel process for obtaining magnesium from sea water involves several reactions. Write a balanced chemical equation for each step of the process. (Use the lowest possible whole number coefficients. Include states-of-matter under the given conditions in your answer.)   In the third step, calcium hydroxide (mixed with seawater) reacts with dissolved magnesium chloride to yield solid magnesium hydroxide and aqueous calcium chloride.     In the fourth step, solid magnesium hydroxide is added to an aqueous hydrochloric acid solution, producing dissolved magnesium chloride and liquid water.       magnesium chloride is melted and this liquid is electrolyzed to yield liquid magnesium metal and diatomic chlorine gas.

Explain in detail the endothermic and exothermic chemical reactions. Describe each using energy diagrams. Give an example for both types of reactions.
