Which row shows the equations for the dissociation of methanoic acid and nitric acid?

  • A$\text{HCOOH(aq)} \rightarrow \text{H}^+\text{(aq)} + \text{HCOO}^-\text{(aq)}$; $\text{HNO}_3\text{(aq)} \rightarrow \text{H}^+\text{(aq)} + \text{NO}_3^-\text{(aq)}$
  • B$\text{HCOOH(aq)} \rightarrow \text{H}^+\text{(aq)} + \text{HCOO}^-\text{(aq)}$; $\text{HNO}_3\text{(aq)} \rightleftharpoons \text{H}^+\text{(aq)} + \text{NO}_3^-\text{(aq)}$
  • C$\text{HCOOH(aq)} \rightleftharpoons \text{H}^+\text{(aq)} + \text{HCOO}^-\text{(aq)}$; $\text{HNO}_3\text{(aq)} \rightarrow \text{H}^+\text{(aq)} + \text{NO}_3^-\text{(aq)}$
  • D$\text{HCOOH(aq)} \rightleftharpoons \text{H}^+\text{(aq)} + \text{HCOO}^-\text{(aq)}$; $\text{HNO}_3\text{(aq)} \rightleftharpoons \text{H}^+\text{(aq)} + \text{NO}_3^-\text{(aq)}$
