5. Which statement describes the charge of an electron and the charge of a proton?
A) An electron and a proton both have a charge of
+1.
B) An electron and a proton both have a charge of
-1.
C) An electron has a charge of +1, and a proton has
a charge of -1
D) An electron has a charge of -1, and a proton has
a charge of +1.

Explanation:

Electrons and protons are both subatomic particles in an atom.

First, analyze both.

Electron

Proton

So, we see that the electron has a charge of -1 and the proton has a charge of +1. The correct answer must be choice D.

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.
