The positive sign of the energy difference in a chemical reaction would indicate that ..........
trasher [3.6K]

Answer:

B) the chemicals are gaining energy from the surroundings.

Explanation:

The positive sign of the energy difference in a chemical reaction would indicate that the chemicals are gaining energy from the surroundings. This is what happens in an endothermic reaction.

In an endothermic reaction, heat is absorbed from the surroundings hence the surrounding becomes colder at the end of the changes.

  • Here the energy change is assigned a positive value.
  • This is because the heat energy level of the final state is higher than that of the initial state.
  • So, the difference gives a positive value.

Determine the percentage composition (by mass) of oxygen in NH4NO3.
Brrunno [24]
