yes
Conserved.
That is false. Assuming an exothermic reaction, e.g., a fusion of hydrogen to helium:The total amount of mass before and after the reaction is the same. (Any energy leaving the atom has a mass equivalent.)The total amount of energy before and after the reaction is the same. (The energy was there previously, in the form of potential energy).
Therefore energy is conserved.
The total amount of energy before and after a transformation will be the same. Energy may pass from one object to another object, or be converted from one type of energy to another, but the total amount doesn't change.
Physical Change-- Same amount of energy, but in different form Chemical Change-- Different amount of energy, and in a different form
The total amount of energy in the universe eye is zero.
The total amount of energy doesn't change in this case.
The total amount of energy doesn't change. However, some useful energy will be converted into unusable energy.The total amount of energy doesn't change.

usable energy changes, while total energy does not
Lighting a match changes chemical energy into heat and light. The total amount of energy
The total amount of energy in any process will neither increase nor decrease.
