Answer:
a. single replacement
Explanation:
Chemical equation:
Cd + H₂SO₄ → CdSO₄ + H₂
In given reaction Cd replace the hydrogen and form cadmium sulfate and hydrogen gas.
Single replacement:
It is the reaction in which one elements replace the other element in compound.
AB + C → AC + B

A + B → AB
Double replacement:
It is the reaction in which two compound exchange their ions and form new compounds.
AB + CD → AC +BD
What you can do is organize them by color, what matter they are in room temperature, their molecular structure, or what kind of conductor in electricity and heat it is. I'm not sure what the format is supposed to look like but first just organize them all in different categories.
<span>Cations mix with anions, so you know NH4+ won't mix with K+ and SO4(2-) won't miix with F-. For the reason that NH4+ and F- together have single charges, they'll mix in a 1:1 ratio, NH4F. There's two charges on SO4(2-), so it'll need two K+ to mix with, K2SO4.</span>
