The solid anhydrous solid CoCl2 is blue in color. Because it readily absorbs water from the air, it is used as a humidity indica
MrRissso [65]

Answer:

CoCl_{2}.(H_{2}O)_{6} is formed and it has three unpaired electrons.

Explanation:

Blue CoCl_{2} reacts with water to produce pink colored CoCl_{2}.(H_{2}O)_{6} complex.

In this complex, Co^{2+} ion forms an octahedral complex with six H_{2}O ligands.

As H_{2}O is a weak field ligand therefore Co^{2+} ion remains in low spin state.

Hence electronic configuration of Co^{2+} ion in this octahedral geometry is t_{2g}^{5}e_{g}^{2} with total three unpaired electrons.

a square boat made from iron has overall dimensions of 2.00 cm x 11.0 cm x 11.0 cm. it has a mass of 213 g. water has a density
Stolb23 [73]
Density of boat  =  \frac{MASS}{VOLUME}
                           
                          =  \frac{213 g}{(2 cm  *  11 cm  *  11cm)}
 
                          =   0.88 g / cm³

Since the density of water is greater than the density of the boat ( 1 > 0.88) then that means, the boat will NOT sink.
