While a certain isotope decays, it emits photons. What kind of decay is happening?
alpha decay
beta decay
gamma decay
positron decay

The answer is (C) on edge2020

Explanation:

gamma decay. A radioactive process in which an atomic nucleus loses energy by emitting a gamma ray (a stream of high-energy photons). When an element undergoes gamma decay its atomic number and mass number do not change.

also i just took the quiz lol

It is C Gamma Decay

Explanation:

I answered C and I got It right

i do not know

explanation:

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
