Question

if sodium mix with tetrachloride what will happen

Answer 1

Hiii friend here is your answer

Na+CCl4=NaCl3+Cl

Answer 2

Not much. Both compounds are bases so there will not be any reaction between them. About the only thing that happens is that you will get a mixture of sodium carbonate and sodium hydroxide. Here’s a link to a video of mixing sodium carbonate and sodium hydroxide

However, if there is a typo and the writer meant to say the reaction of sodium bicarbonate and sodium hydroxide, then a reaction will occur and it is:

NaOH + NaHCO3 → Na2CO3 + H2O
