hore total energy than the reactants, the AG will be and if the reactants have more total energy than the products the AG will be

If the dissolution of a salt in water is an endothermic reaction, how will the temperature of the solution change as the reaction proceeds? O The solution will heat up. O There is insufficient information to answer the question. O The solution will cool down. There will be no change in temperature.

The amount of energy required to raise the temperature of a substance by 1 K (1 °C) is its heat capacity. If the amount of the substance heated is one gram, it is the ........ heat

A system does 675 kJ of energy onto its surroundings while releasing 1543 J of heat. What is the change o energy of the system?

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

For exothermic reactions, the products have lower energy than the reactants.Explain why?

From a molecular viewpoint, where does the energy absorbed in an endothermic chemical reaction go? Why does the reaction mixture undergo a decrease in temperature even though energy is absorbed?

All chemical reactions that are used as fuel must... O Have products higher in energy than reactants. O Have products lower in energy than réactant. O Have products with the same energy as the reactants.
