Consider the reaction when aqueous solutions of ammonium carbonate and chromium(III) chloride are combined. The net ionic equation for this reaction is:

Explanation:

Spectator ions are defined as the ions which does not get involved in a chemical equation or they are ions which are found on both the sides of the chemical reaction present in ionic form.

The balanced molecular equation is:

The equation can be written in terms of ions as:

The ions which are present on both the sides of the equation are ammonium and chloride ions and hence are not involved in net ionic equation.

Hence, the net ionic equation is

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
