A nuclear reaction is when atomic nuclei combine, forming a new chemical element
A chemical reaction occurs when electrons from the last layer of atoms mix, forming molecules that have the same chemical elements as the reactants.
According to these definitions
C + 2 S → CS2
in a chemical reaction where electrons mix.
Answer:
a) three times greater
Explanation:
Remember the heat capacity is the necessary heat to increase the temperature 1 ºC to an specific mass of the substance, in this case since the water and the metal have the same mass, is easier to compare just the neccesary heat.
Since water increases 20 ºC and the metal 60 ºC, it was neccesary 3 times of the quantity of heat to the same amount of mass of the two different susbtances.

Answer:
Substances can change phase — often because of a temperature change. At low temperatures, most substances are solid; as the temperature increases, they become liquid; at higher temperatures still, they become gaseous.

Explanation:
#4. It says "someone sitting in a chair" So the objects involved are the person and the chair. D is the answer because it talks about the action/reaction forces between the person and the chair.
#5. Work = Force (parallel to direction of distance) * distance. A, B and D are not correct because there is no distance. C. is the best answer
