Answer:
1+
Explanation:
the number of protons tells you which element it is in the periodic table, you can notice that there is 1 less electron that then there is protons which means that the element had to give 1 electron away. When you get rid of 1 e- you have 1 proton more that electrons so that's why it's 1+
also the element is Cr
The shape of the molecule is trigonal planar.
For example, H₂O:
..

the conversion of liquid to vapours is a change in state of a system from one state to other
there are basic two differences between three states of matter
1. thermal energy: gas has highest thermal energy tthen liquid and least us of solids
2. intermolecular forces of attractions
solids have highest intermolecular forces of attraction , then liquid and least in gas
sovas we increase the temperature the forces if attraction decrease s and thermal energy increases.
So when we heat liquid more moleculws gets energised attaining thermal motion in the range of gas thus the rate if evaporation increases.
