Explanation

A hydrogenation reaction occurs when vegetable oils are converted to fats.

The double bonds of vegetable oils are broken down resulting in a saturated fat i.e. ghee.

Explanation

CaCO₃ (Calcium carbonate)

No, it is not hygroscopic.

It does not absorb moisture significantly → NOT a desiccating agent

Explanation

 In $text{K}_2text{Cr}_2text{O}_7$, total oxidation state must be 0. K = +1, O = –2, so Cr must be +6 to balance the equation:

$$2(+1)+2(x)+7(–2)=0\Rightarrow x=+6$$

Explanation

: CsCl has a body-centered cubic (bcc) structure, where each Cs⁺ ion is surrounded by 8 Cl⁻ ions and vice versa.

Explanation

 CH₃COONH₄ – Salt of weak acid (acetic acid) and weak base (ammonia) → Can be slightly acidic, neutral, or basic depending on their relative strength, but usually basic if acetate dominates
