Make sure you express your answer in the correct number of significant digits. In chemical formula you may use: Any chemical element. HNO3 Express your answers as ions separated by a comma. NISHAT A answered on June 17, 2015. Express your answer using two significant figures. NaCH3COO(aq)+HNO3(aq)----->NaNO3(aq)+CHOOH(aq . HNO3 is strong electrolyte and CH3COOH is weak electrolyte. Calculate the original [HNO3]. At the equivalence point, the solution will be neutral. Write the balanced molecular, complete ionic, and net ionic equations for each of the following acid-base reactions. Show all your steps. The O bonded to H has SN = 4 (two bonding pairs and two lone pairs). Express your answer to two significant figures and include the appropriate units. Capitalize the first letter in chemical symbol and use lower case for the remaining letters: Ca, Fe, Mg, Mn, S, O, H, C, N, Na, K, Cl, Al. Express your answer as a chemical equation. The N atom is sp² hybridized. (2) Nitric acid is usually purchased in concentrated form with a 70.3% HNO3 concentration by mass and a density of 1.41 g/mL.
