37. An atom is electrically neutral because the (1) number of protons equals the
number of electrons
(2) number of protons equals the
number of neutrons
(3) ratio of the number of neutrons
to the number of electrons is 1:1
(4) ratio of the number of neutrons
to the number of protons is 2:1 37

(1) number of protons equals the

number of electrons

Explanation:

for points guys

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.
