(iv) It has a pungernt odour​

When sodium hydrogen carbonate is added to acetic acid then carbon dioxide (CO2) gas is evolved.

Explanation:

When sodium hydrogen carbonate is added to acetic acid a gas is evolved Which of the following statements are true about the gas evolved i it turns lime water milky II it extinguishes a burning splinter III it dissolves in a solution of sodium hydroxide IV it has a pungent Odour?

i believe the answer is a.

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 :
