The bonds of the products store 22 kJ more energy than the bonds of the reactants. How is energy conserved during this reaction?
O A. The reaction system absorbs 22 kJ of energy from the
surroundings.
B. The reaction creates 22 kJ of energy when bonds form.
C. The reaction uses up 22 kJ of energy when bonds break.
D. The surroundings absorb 22 kJ of energy from the reaction
system.

In a laboratory experiment, a fermenting aqueous solution of glucose and yeast produces carbon dioxide gas and ethanol. the solution was heated by burning natural gas in a bunsen burner to distill the ethanol that formed in the flask. during the distillation, the ethanol evaporated and then condensed in the receiving flask. the flame of the burner was kept too close to the bottom of the flask and some of the glucose decomposed into a black carbon deposit on the inside of the flask. during this experiment the following changes occurred. which of these changes involved a physical change and not a chemical change? check all that apply. 1-condensation of ethanol 2-evaporation of ethanol 3- formation of carbon dioxide gas from glucose burning of natural gas 4-formation of ethanol from glucose by yeast 5-formation of a carbon deposit inside the flask
