1.	When Na_2CO_3 . 10 H_2O is kept open in air, it(a)absorbs moisture(b)loses water to form anhydrous salt(c) loses water to form a monohydrate(d) decomposes to give CO_2 and Na_2O.
Answer» ABSORBS moisture loses WATER to form anhydrous salt loses water to form a monohydrate DECOMPOSES to GIVE `CO_2 and Na_2O`. Solution : loses water to form a monohydrate
