How would you balance: Na + H2O –> NaOH + H2?
February 20th, 2023
##2Na + 2H_2O -> 2NaOH +H_2##
You have to count the number of atoms in both sides of the reaction to be equal, to make it a little easier you can make a list. So in the equation ##Na+H_2O->NaOH+H_2##, there are
##1-Na-1##
##2-H-3##
##1-O-1##
So you multiply NaOH and H2O by 2, so you have 4 hydrogens in both sides, and then multiply Na by 2 to be equal to the NaOH you previously multiplied.
