During a chemical reaction, the most likely occurring is mass conservation. According to law of conservation of mass, total mass in a reaction is conserved.
What is law of conservation of mass?According to the law of conservation of mass, the total mass in a chemical reaction or in a physical change is conserved. Simply, mass is neither created nor destroyed.
When a chemical reaction takes place, no new atoms are created and the properties of the reactant species cannot be maintained after reaction.
Molecules of any reactant is not lost during a reaction. The total mass in the reactant side of a balanced reaction will be equal to the total mass in product side.
Therefore, the mass conservation is likely to occur during a chemical reaction. Thus, option d is correct.

the ____ temperature of an object the lower its thermal energy
Thermal energy is the average sum of all kinetic energy of all the molecules of gases. The lower the temperature of an object the lower its thermal energy.
What is Thermal energy?
Thermal energy is a energy which is possess by a moving object. It is directly proportional to kinetic energy of the molecules. It is very difficult to find the correct value of kinetic energy so we find average kinetic energy. Which is very easy to calculate as compared to calculating kinetic energy.
Mathematically,
K.E=2/3KT
Where,
K= Boltzmann constant
T is the temperature
Average kinetic energy is directly proportional to temperature. It is not dependent on the type of gases or mass of gases. The lower the temperature of an object the lower its thermal energy.
Therefore, the lower the temperature of an object the lower its thermal energy.
