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​

What happens to the temperature of a substance when the average kinetic energy of its particles increases?

Imagine if during the cathode ray experiment, the size of the particles of the ray was the same as the size of the atom forming the cathode. which other model or scientific observation would have also been supported? 1. this would support dalton's postulates that proposed the atoms are indivisible because no small particles are involved. 2. this would support bohr's prediction about electrons moving in orbits having specific energy. 3. this would support bohr's prediction about electrons being randomly scattered around the nucleus in the atom. 4. this would support dalton's postulates that proposed that atoms combine in fixed whole number ratios to form compounds.

How can the number of core electrons be determined from the periodic table
