The following equation describes how sodium and chlorine react to produce sodium chlorine

The equation is 2Na + Cl₂ ⇒ 2NaCl. Two sodium atoms react with a chlorine molecule (Consisting of two chlorine atoms) that produces two molecules of sodium chloride (common table salt).

Ch4 is nonpolar and insoluble in water. since all of the hydrogen atoms are evenly spread around the carbon atom even through the c h bond is polar all the poles cancel each other out.
