Answer:
4) 2Na + Cl2 → 2NaCl
5) 2Mg + O2 → MgO
6) 2H2 + 2O2 → 2H2O
Explanation:
4) In order for it to be well balanced, yeah you've got to add 2 in front of Na before the reaction and after the reaction.
5) Add 2 in front of Mg bcuz of the same reason in number 4 but you don't have to add 2 in front of the others bcuz it's alrd well balanced.
6) Tbh for this one, it got me staring at my cat until he freaks out but like yeahh, I tried :')

Answer:
Ionic bonds are opposite, whereas Covalent bonds are opposite.
Explanation:
Two opposite ions attract each other and form the ionic bond. Covalent bonding is a form of chemical bonding between two non metallic atoms which is characterized by the sharing of pairs of electrons between atoms and othercovalent bonds.
Examples:
Sodium Chloride and Sodium Fluoride are examples of <em>Ionic</em><em> </em><em>bonds</em><em>.</em>
<u>and</u>
Water and Carbon Dioxide are examples of <em>Covalent</em><em> </em><em>bonds</em><em>.</em><em> </em>
