Question

Cu + HNO3 = Cu (NO3)2 + NO2+ H2O

balance by abcd method.
if you don't Know don't give the answer please and if anyone knows give the answer in abcd method.please​

Answer 1

Answer:

Cu + 4HNO3 → Cu(NO3)2 + 2NO2 + 2H2O

Explanation:

To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. The balanced equation will appear above.

Use uppercase for the first character in the element and lowercase for the second character. Examples: Fe, Au, Co, Br, C, O, N, F.

Ionic charges are not yet supported and will be ignored.

Replace immutable groups in compounds to avoid ambiguity. For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will.

Compound states [like (s) (aq) or (g)] are not required.

You can use parenthesis () or brackets [].
