We CAN do subscripts on this board but it's usually too much trouble and all of us understand that the 2s are subscripts. We use the caret(^) to show a superscript like this. 2^3 is 2 cubed = 8.
The reaction is a single replacement reaction. You are replacing H with Na.
What type of chemical reation is :
Na + H2O---) NaOH + H2? The 2s are subscripts but I couldn't get it to type that way.
