It is not balanced since there are 2 Cl molecules on the left side, and only 1 on the right side. In order to balance this, you would need to make sure there are the same amount of all the molecules on both sides...
4Na + 2Cl2 = 4NaCl
Hope this helps :)
Kinetic energy and mechanical energy I believe.
The substance that has bonded with the greatest ionic character is CaCl₂; option C.
<h3>What are ionic bonds?</h3>
Ionic bonds are bonds formed between elements of atoms by transferring an electron or electrons from an electropositive element to an electronegative element.
The greater the electronegative difference between the two atoms forming the bonds, the stronger the ionic character of the bond. This is because the ionic bond is a result of electrostatic forces of attraction between the oppositely charged ions.
Considering the given compounds:
- CCl₄ - the bond between the atoms are covalent bonds
- CuCl₂ - the bond between the atoms are ionic bonds but the electronegativity difference is not very large
- CaCl₂ - the bond between the atoms are ionic bonds and the electronegativity difference is quite large
- NCl₃ - the bond between the atoms are covalent bonds
Hence, the bonds between CaCl₂ the greatest ionic character.
