Today i learnt 9 chemical equations and their equilibrium constant. And I know I should omit the square bracket of the complex ion when I'm writing the equilibrium constant. Thank you Mr Fung!

Start to think a lot of the past, searching photos. To discover more means more and more sorrows, esp when i remember the meaning of my passwords. Isn't it a bit late, or is it a bit late to envy?

Just another day.
