Answer:
CaBr2 is a colorless solid and the charge on Calcium is +2
Explanation:
CaBr2 is a colorless solid at room temperature.
Other properties include -
a) It is a crystalline solid
b) Melting point of 765°C.
c) It is deliquescent
d) Soluble in water and absolute alcohol.
The charge of Br is -1. Here two atoms of Br attaches with one atom of calcium. Hence the charge of calcium is +2
<u>Explanation:</u>
<u>Similarity between the two:</u>
Molecular formula and structural formula gives the exact number of atoms of different chemical elements that are present in a compound.
<u>Difference between the two:</u>
Structural formula gives us the relative positions of the atoms that are present in a compound whereas molecular formula does not give us the relative positions of the atoms. But it gives us the ratio of atoms in a given compound.
