1.	A white coloured powder is used by doctors for supporting fractured bones. (a) Write chemical name and formula of the powder. (b) When this white powder is mixed with water a hard-solid mass is obtained. Write balanced chemical equation for the change.
Answer» a. The chemical name and formula of the white coloured powder which is used by doctors for supporting fractured bones is: - Chemical name – Calcium sulphate hemihydrate Formula - CaSO₄ \(\frac12\)H₂O b. When this white powder is mixed with water a hard-solid mass is obtained. The balanced chemical equation for the change is: - CaSO₄.\(\frac12\)H₂O + 1\(\frac12\)H₂O → CaSO₄.2H₂O

a. The chemical name and formula of the white coloured powder which is used by doctors for supporting fractured bones is: -

Chemical name – Calcium sulphate hemihydrate

Formula - CaSO₄ \(\frac12\)H₂O

b. When this white powder is mixed with water a hard-solid mass is obtained. The balanced chemical equation for the change is: -

CaSO₄.\(\frac12\)H₂O + 1\(\frac12\)H₂O → CaSO₄.2H₂O
