Sulphuric acid is a typical strong acid. (a) Change the equations given into a different format.

(i) Mg + H2SO4 MgSO4 + H2

Change into a word equation.

(ii) lithium oxide + sulphuric acid lithium sulphate + water

Change into a symbol equation.

(iii) CuO + 2H+ Cu2+ + H2O

Change the ionic equation into a symbol equation.

(iv) Na2CO3 + H2SO4 Na2SO4 + CO2 + H2O

Change into a word equation.

(b) When sulphuric acid dissolves in water, the following reaction occurs.

H2SO4 + H2O HSO4 + H3O+

Explain why water is behaving as a base in this reaction.

(c) Sulphuric acid is a strong acid, ethanoic acid is a weak acid.

Explain the difference between a strong acid and a weak acid​

a

explanation:

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of carbon is as shown here in the image.

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 :

your answer is c) plasma
