If a compound gives hydrogen ion and sulphate ion in the solution state. Answer the following related to the compound. (a) write the name and molecules formula of the compound..
(b) write the balanced chemical equation of the chemical reaction taking place between this compound in aluminium?

The compound is sulphuric acid

It's molecular formula is H2SO4

Aluminium metal dissolves readily in dilute sulphuric acid to form solutions containing the aquated Al(III) ion together with hydrogen gas, H2. The corresponding reactions with dilute hydrochloric acid also give the aquated Al(III) ion.

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
