What is a chemical reaction?
It should be noted that a chemicalreaction simply means the process by which substances are converted to another substance.
In this case, controlling the rate of a chemical reaction is useful to the professions to improving production.
By finding out how fast products are made, one can develop methods to into such production.

Answer C
(2) They have identical molecular structures and different properties.
(3) They have different molecular structures and identical properties.
(4) They have different molecular structures and different properties.
Answers
Answer: Option (4) is the correct answer.
Explanation:
In an molecule there are two oxygen atoms and in a
molecule there are three oxygen atoms.
So, there will be different number of electrons involved in the bonding of atoms for both and
molecules.
Therefore, both of them will have different structure and reactivity.
Thus, we can conclude that the statement they have different molecular structures and different properties, correctly describes two forms of oxygen, O2 and O3.

B. A 2 kg pot at 120°C
C. A 5kg pot at 25°C
D. A 2 kg pot at 25°C
Answers
Final answer:
The 2 kg pot at 25°C has the least thermal energy because it has both a smaller mass and a lower temperature than the other options.
Explanation:
The thermal energy of an object is related to both its mass and its temperature. In this case, we are considering iron pots of different masses and temperatures. Given the options, the 2 kg pot at 25°C would have the least thermal energy. This is because it has both a smaller mass and a lower temperature than all the other options listed.
The thermal energy is calculated by multiplying the mass, specific heat, and change in temperature. An object with a smaller mass and lower temperature would therefore have less thermal energy.

Answer:
Molecules in food contain chemical energy that cells use to produce Adenosine triphosphate ATP. Respiration is that the method by that cell get energy within the sort of ATP. Adenosine triphosphate captures energy obtained from the breakdown of food molecules and releases it to fuel alternative cellular processes. ATP, is that the primary carrier of energy in cells. Once energy is required by the cell, it's born-again from storage molecules into ATP.
