State 3 ways of preparing acids and write an equation for each

Synthetic Method: Acids are prepared by direct combinaion of elements

                          Equation: H2+C1> 2HC1

By Dissolving acidic oxides into water: Some oxides dissolve in water to give acids

                           Equation: SO3+H2O> H2SO4

By the action of an acid on the salt of another acid: An acid having a higher boiling point can react with the salt of an acid of lower boiling point to produce an acid.

                             Equation:H2SO4 + NaC1>NaHSO4 + HC1

fearlessness is your answer

with what words? i dont see them
