In an endothermic reaction products are <u>HIGHER </u>than reactants in potential energy and <u>LESS </u>stable.
Explanation:
Energy is input into the reaction in an endothermic reaction. This means the products are of a higher energy level than the reactants. Therefore the reaction increases Gibb's free energy and reduces entropy. Remember in thermodynamic stability involves an increase in entropy and a decrease in Gibbs free energy. Therefore the products are less stable than the reactants. This is why endothermic reactions do not occur spontaneously like exothermic reactions.
<span>According to the law of conservation of energy, the total amount of energy in the universe will remain the same. Therefore, energy cannot be created or destroyed, only transformed.

Answer:
45.2 mL must be meausred for the experiment
Explanation:
The density of the acetic acid is 1.105 g/mL, so this data gives the information about how many grams are contained in 1mL of volume.
Notice that 1 mL = 1 cm³
Acetic acid Density = Acetic acid mass / acetic acid volume
1.105 g/mL = 50 g / acetic acid volume
Acetic acid volume = 50 g / 1.105g/mL ⇒ 42.5 mL
answer: elements are on the periodic table
