What happens to the total energy in a closed system? A) The energy is conserved and does not change.

B) The energy grows and increases over time.

C) The energy is unstable and changes unpredictably.

D) The energy is destroyed and disappears over time.

I think the answer might be A

Explanation:

In a closed system, the total energy always remains constant.

hope this helps:)

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
