Colemanite + G (compound) rarr A + B + C
`Coverset(Delta)rarrD+E("gas")overset("Baryta water")rarr`
`"milky"overset(E+H_(2)O)rarr"milkyness disappears"`
`B + E ("gas") rarr A + G , A overset(Delta)rarr F + B`
`F + CuO rarr "Blue bead"`
F with 3 moles of water gives 2 moles of compound `'H'. 'H'` on heating to `100^(@)C` gives `'I'.'I'` is :
