The total bonding energy for the products of a reaction is 1230 kJ/mol and the bonding energy of the reactants is 565 kJ/mol. Calculate the change in enthalpy, and classify the reaction as endothermig or exothermic. -665 kJ/mol, endothermic
665 kJ/mol, exothermic
-665 kJ/mol, exothermic
665 kJ/mol, endothermic

Will give brainliest it is a lab from k12 here is the linkfor each metal that participated in a chemical change, write the type of metal it is, based on your examination of the periodic table. type your answer here. (score for question 3: of 5 points) 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. type your answer here. (score for question 4: of 5 points) make a general statement about the reactivity of the metals in this experiment. type your answer here.

Choose all the answers that apply. ionic compounds dissolve easily in water do not dissolve in water have low melting points have high melting points conduct electricity when melted
