The first two periods of the start of the day was Chemistry lesson. When we go to the lab, it means that there’ll be hands on experiment to do, if we stay in the class, it means that the Chemistry teacher, Mrs Goh will teach theorectically.
(Beng Tian was playing with the tube.)
What we did today (yesterday according to the date) was to determine whether the size will affect the rate of reaction. There Calcium Carbonate mixed with Hydrocholoric Acid and it’s then stucked with a tube connected to a burette to observe the collected gas. =)
That’s what we did. The real main thing was just to observe how gas is collected. I wonder if you have any idea what I am talking about? I am talking in Chemistry Language. Haha. It’s just a post about something in school. Cheer. Happy Earth Hour Day.
