Question

if 2Na + Cl2 --> 2NaCL ... what happened to the two on Cl? and if 2H2O --> 2H2 + O2 what happened to the 2 on the O as well? could you please answer this in like sort of a simple way? my brain is mush at the moment lol.

Answer 1

Step-by-step explanation:

when a big number is behind a compound, it means there is 2 of it.

for example 2Na would mean there is a sodium atom and another sodium atom not joined together, but they're just near.

when there is a 2 (which should be small and at the bottom) after an atom, it means there are 2 of that atom.

i hope this helps
