balance the formula
Cu(OH)2(s) + HNO3(aq) -> H2O(l) + fine the formula here(aq)
i did the H20 but i don't know the other formula i thought it was CuNO3 but that's wrong and idk what to do with the extra O
This is an acid-base reaction. It forms water + salt and the oxidation state (valence) of the Cu in Cu(OH)2 is +2; therefore, the formula for the nitrate of Cu is Cu(NO3)2. You tried to make an oxidation-reduction equation out of it and that won't work.
Cu(OH)2(s) + 2HNO3(aq) ==> 2H2O(l) + Cu(NO3)2
so for this equation:
HC2H3O2(aq) + Ca(OH)2(aq) -> H2O(l) + find the formula here
the last part would be CaOC2H3O2?
im a little confused. did the O fromt he H2O come from (OH)2?
