(b) Sulphuric acid is used in the manufacture of this fertiliser and some has leaked onto fittings made of a magnesium alloy. This reaction produces hydrogen gas
Mg(s) + H2SO4(aq)
MgSO4(aq) + H2(g)
Design a method to measure the rate of this reaction, and list the measurements

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.
