A chemist wants to know if mixing two liquids, Substance A and Substance B, will result in a chemical reaction. The chemist pours 10 milliliters of Substance A into a beaker containing 30 milliliters of Substance B and observes what happens. Name four changes in the resulting mixture which would indicate that a chemical reaction occurred between Substance A and Substance B?

answer: they produce more slow than unicellular organisms.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
