For the reaction to take place the energy of the reactants must reach to the energy level of the products:
we have 900 J in the reactants and 9000 J for the products so the reactants need 8100 J to reach to the value of energy of products (900 + 8100 = 9000)
So the correct answer is C. <span>The reaction absorbs 8100 J of energy from the surroundings as it proceeds. </span>
Oxygen, glucose and starch
Oxygen and glucose are produced during photosynthesis. Glucose is then stored as starch.

Mass is the amount of matter in an object, and weight is the downward pull on an object due to gravity. Which property of physical changes explains why matter is conserved in a physical change? The bonds between atoms do not break; it is only the arrangement that changes.

If a freezer is not cold, maybe the condenser coils are dirty. You should clean these every 6-12 months. If not check the evaporator fan motor, it draws air over the evaporator coil and circulates it through the freezer. Your last option is to start relay, the start relay provides power to the compressor. Hope this helped!
