It shows that gold (all) atoms are made of mostly empty space. The alpha particles go right through because they hit nothing in the atoms which showed Rutherford that atoms are mostly empty space.
<span>An Arrhenius base adds ions into water when added to the water hence it increases the concentration of ions in aqueous solution. Therefore, KOH is an example because the ions added to the water are called OH-ions.</span>

Answer:
A chemical reaction expresses a chemical change. For example, one chemical property of hydrogen is that it will react with oxygen to make water. We can write that as follows:
hydrogen reacts with oxygen to make water
We can represent this chemical change more succinctly as
hydrogen + oxygen → water
where the + sign means that the two substances interact chemically with each other and the → symbol implies that a chemical reaction takes place. But substances can also be represented by chemical formulas. Remembering that hydrogen and oxygen both exist as diatomic molecules, we can rewrite our chemical change as
H2 + O2 → H2O
