Question

H2SO4 + Ca(NO3)2 = (пожалуйста напишите молекулярное и ионные уравнения. Заранее спасибо!)

Answer 1

$H_2SO_4 + Ca(NO_3)_2 = CaSO_4$ (стрелка вниз) $+ 2HNO_3$

$2H^++SO_4^{2-} + Ca^{2+} + 2NO_3^- = CaSO_4$ (стрелка вниз) $+ 2H^+ + 2NO_3^-$

$Ca^{2+} + SO_4^{2-} = CaSO_4$ (стрелка вниз)

Molecular and Ionic Equations for the Reaction H2SO4 + Ca(NO3)2

When sulfuric acid (H2SO4) reacts with calcium nitrate (Ca(NO3)2), it forms a molecular equation and an ionic equation. Let's break down the reaction into its molecular and ionic forms.

Molecular Equation:

The molecular equation for the reaction between sulfuric acid and calcium nitrate is as follows: H2SO4 + Ca(NO3)2 → CaSO4 + 2HNO3

Ionic Equation:

To write the ionic equation, we need to first break down the reactants and products into their respective ions: - Sulfuric acid (H2SO4) dissociates into hydrogen ions (H+) and sulfate ions (SO4^2-). - Calcium nitrate (Ca(NO3)2) dissociates into calcium ions (Ca^2+) and nitrate ions (NO3^-).

The ionic equation for the reaction is as follows: 2H^+ + SO4^2- + Ca^2+ + 2NO3^- → CaSO4 + 2H^+ + 2NO3^-

In this ionic equation, the spectator ions (ions that appear on both sides of the equation and do not participate in the reaction) are the hydrogen ions (H^+) and the nitrate ions (NO3^-). Therefore, the simplified ionic equation is: SO4^2- + Ca^2+ → CaSO4

This simplified ionic equation represents the essential chemical change that occurs during the reaction between sulfuric acid and calcium nitrate.
