On an endothermic potential energy diagram, what is true for all products? The products are at the same energy level as the reactants. The products are at a lower energy level than the reactants. The products are at a higher energy level than the reactants. The products do not have energy.

Certain chemical reactions are endothermic while others are exothermic. In each of the following statements regarding a chemical reaction, state whether the reaction is endothermic or exothermic:   (make sure to answer all 4 statements) a.  ΔH has a positive value   b.  The energy of the reactants is greater than the energy of the products.   c.  Energy is released in the reaction.   d.  The bonds in the products are stronger than the bonds in the reactants.

what happens to the energy absorbed during an endothermic reaction

Consider a hypothetical chemical reaction: A+B C+D (In this equation A, B, C and D stand for some unknown chemical formulas.) Here is an energy diagram for the reaction: energy (kJ/mol) 400- 300- 200- 100- 0 A+B C + D reaction coordinate Use the energy diagram to answer these questions.

are the products are the things that are mixed together to start a reaction?

heat content in the surroundings of an endothermic reaction decreases, because the energy contained in the products is lower than the reactants the reaction absorbs heat energy the energy contained in the reactants is lower then the products heat energy is destroyed during reactions

4. The specific heat of water is quite high at 4.184 J/gC. Explain how life on this planet would be different if the specific heat of water were that of lead at 0.128 J/gC.

Which statement is correct for the characteristics of an endothermic reaction? Select one: a. There is a net input of energy, and energy is a product of the reaction. b. There is a net input of energy, and energy is a reactant in the reaction. c. There is a net release of energy, and energy is a reactant in the reaction. d. There is a net release of energy, and energy is a product of the reaction.

4. Determine the final temperature of the solution formed when 0.31 g sodium oxide is added to 100 ml water in a calorimeter. Assume that the volume of the resulting solution is 100 ml. The temperature before reaction is 19°C. The heat capacity of the calorimeter is 20J/°C. Suppose that the specific heat and density of the solution are the same as those of water. Write down all the reaction equations needed to solve this exercise.
