i was thinking one day if middle school and high school could be all computer operated.?

They are already starting to do that, and I don't like it. Then again, i'm kinda old-fashioned. I think we are becoming way too dependent on machines. What if something happened where a main source crashed and the computers didn't work anymore (a la Y2K) then what? Everything is online, so we'd have nothing. People put their lives on their cell phones & sidekicks, then when they loose it, they loose everything. That's why I love good ol' pen and paper. Doing everything by computer also minimizes human contact. I'm not a robot damnit!

How to balance equations(middle school)?

2 Mg + 1O2 ----------> 2MgO

2N2 + 3H2 -----------> 2NH3

This is basic math. You multiply the number in front of the element by the subscript to try to make it equal.

In the first equation you already have 2 oxygen on one side, so you put 2 infront of MgO. Because there is 2 Mg on the right side, you need to add 2 on the left side. Now, it is balanced.

In the second equation, because there is already 2 of N, you put 2 onto the right side to balance N. But 2 times 3 = 6. So there are 6 of carbon. So you try to get 6 of carbon on the left side by adding 3 there. 3x2 = 6. So the equation is now balanced.
