The student's lab manual says to mix some of his na2co3 solution with an aqueous solution of copper(ii) sulfate (cuso4)

write a balanced chemical equation to show the reaction. use state symbols.

Explanation:

When the student mixed the solution sodium carbonate with solution of copper(II) sulfate ; Copper Hydroxocarbonate , sodium sulfate and carbon dioxide gas was obtained as a products.

The balanced chemical reaction

Where:

= Copper(II) Hydroxocarbonate

= Sodium carbonate

= Copper(II) sulfate

= Sodium sulfate

= Carbon-dioxide

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 :

the dependant variable is spilled water

the independent is the heat
