Predict the geometry about each interior atom in acetic acid:
aleksandr82 [10.1K]

The atomic structure of the acetic acid is:

                        H     O

                        l       l

                H – C – C – O – H

                        l

                        H

 

We can see from the structure that there are 2 interior atoms, and these are all Carbon atoms.


The geometry is:

Tetrahedral on First Carbon

Trigonal Planar on Second Carbon

Burka [1]

Answer:

Anhydrous calcium chloride  dissolves and becomes liquid

Anhydrous copper (ii) sulphate will produce crystal particles

Explanation:

Anhydrous calcium chloride is deliquescent and hence when it is exposed to air, it absorbs water from air. After absorbing water, it dissolves and after some time a pool of clear liquid appears.

Anhydrous copper (ii) sulphate will form crystal structures  and the following reaction will takes place

CuSO4 + 5 H20 --> CuSO4.5H2O
