Regarding the Chemical reactions, consider the following statements:1...

Explanation:

Statement 1:
- New atoms are not produced in a chemical reaction. Atoms are rearranged to form new substances, but the total number of atoms remains the same before and after the reaction. This is known as the Law of Conservation of Mass.

Statement 2:
- Exothermic reactions release heat to the surroundings, rather than absorbing it. This results in an increase in temperature in the surroundings. Endothermic reactions, on the other hand, absorb heat from the surroundings.

Therefore, both statements 1 and 2 are incorrect. Chemical reactions involve the rearrangement of atoms to form new substances and exothermic reactions release heat to the surroundings.

Regarding the Chemical reactions, consider the following statements:1...
  • During a chemical reaction atoms of one element do not change into those of another element.
  • Nor do atoms disappear from the mixture or appear from elsewhere, in fact chemical reactions involve the breaking and making of bonds between atoms to produce new substances. Exothermic reactions are accompanied by release of Heat.
