(07.01 MC) A student made a sketch of a potential energy diagram to represent an exothermic reaction. A curve line graph is shown. The y axis of the graph has the title Potential Energy and kJ written in parenthesis. The x axis of the graph has the title Reaction Pathway. The curve begins at a lower level and ends at a slightly higher level. A broken horizontal line is shown from a point labelled x on the y axis to the point where the curve begins. Another broken horizontal line is shown from a point labeled Y on the y axis to the point where the curve ends. Explain, using complete sentences, why the diagram made by the student is correct or incorrect. Be sure to also explain what the values of X and Y represent. (10 points)

Many free radicals combine to form molecules that do not contain any unpaired electrons. the driving force for the radical–radical combination reaction is the formation of a new electron‑pair bond. consider the chemical equation. n(g)+no(g)⟶nno(g) n(g)+no(g)⟶nno(g) write lewis formulas for the reactant and product species in the chemical equation. include nonbonding electrons. n(g)n(g) select draw rings more erase select draw rings more erase select draw rings more erase n no(g)

3.09 lab: reaction of metals 1 which combinations of substances resulted in a chemical change? for each metal that participated in a chemical change, write the type of metal it is, based on your examination of the periodic table. were there any metallic compounds that did not react with either the acid or the base? write the type of metal, based on your examination of the periodic table. make a general statement about the reactivity of the metals in this experiment.
