Solution:
(a) Borax is warmed firmly
Borax goes through different changes when warmed. It is losing atoms and expands of water right away. Then, at that point, it turns into a clear fluid, which sets to shape a glass-like material called a borax globule.
(b) Boric corrosive is added to water
At the point when boric corrosive is added to water, it acknowledges electrons from – OH particle.

(c) Aluminum is treated with weaken NaOH
Aluminum responds to sodium tetrahydroxoaluminate(III) by framing weaken NaOH. In this cycle, hydrogen gas is freed.
