They both contain polyatomic ionic.
and
are both polyatomic ions.
"Poly-" = many
"ions" = have a + or - charge
So, yes, these are ions that are made up of several atoms (not just one atom like
)
In exothermic reactions, the products have higher energy than the reactants, and in endothermic reactions, the reactants have higher energy than the products.
