word equation

Al2(SO4)3 + 3 Ca(OH)2 → 3CaSO4 +  2Al(OH)3

Explanation:

1 mole of aluminium sulfate on reaction with 3 moles of calcium hydroxide gives 3 moles of calcium sulfate and 2 moles of aluminium hydroxide.

Al2(SO4)3 + 3 Ca(OH)2 → 3CaSO4 +  2Al(OH)3

here we have 2 moles of aluminium hydroxide so that aluminium on both the side can balance.

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 :
