Okay here is the thing:

1x0=0
2x0=0
What we have there is two equations right?

There is a rule in math that whenever two equations have the same result we can equal them right? Which leave us with:

1x0=2x0
0/0 X1 = 0/0 X2

Since there is zero on both side we cut it so...

1=2

What am i doing wrong?

...

Being serious, can someone explain the limit thing again, I really forgot that since didn't use it IRL not even once, thank you Law University.

Limit means "tending towards". For example, in the equation x-2/x, if I used limit x -> 2, I would find that the value would *tend* towards 0, but not actually reach zero. For solving limit related problems, you will mostly not get problems like the one mentioned where you can plainly substitute the limiting value to get the solution, and you'll have to simplify the equation when it's in the form of variables, and finally substitute in the limiting value so as to get an answer in definite form.

Hope I helped.

It's a polar molecule and it's amphiprotic; ie it can act as a base to accept a proton to form H3O+ or donate a proton to form OH-. Also has a fucking high specific heat capacity and does cool shit like surface tension and capillary action due to intermolecular hydrogen bonds. Also its maximum density occurs at around 4 degrees Celsius which is explained by chemical physics way beyond that of a first year uni student like myself.

Oh no please no more chemistry.
