What is the chemical equation of radium and (CO3)-2?

Answer 1

Radium has an oxidation state of +2, Oxygen has an oxidation state of -2.....so it'll look like this

Skeleton equation: Ra + O2 --> RaO....

Balanced equation 2Ra + O2---> 2RaO

Answer 2

radium is a chemical element not a compound so it's equation would simply be Ra, if you want an example of an equation then Radium Bromide would be RaBr2.

Answer 3

It turns out that radium is a chemical element. It has the chemical symbol Ra, and not a chemical equation.

Answer 4

The chemical reaction is:
Ra + 2 H2O = Ra(OH)2 + H2

Answer 5

Radium carbonate is RaCO3. This a formula not an equation.
