Answer» O→2NaOH+H2Explanation: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+H2O→NAOH+H2 , there are1−Na−12−H−31−O−1So 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. |
