Hi everyone, Been very busy, as tomorrow is the Science Common Test(C.T) & Friday is the Chinese C.T. For Science we are tested on Chapters 5, 6,15 of our textbook-----Elements, Compounds & Mixtures, Separation of Mixtures and Ecology. Our Home Economics test is also tomorrow.For Chinese we are tested on vocabulary, proverbs and phrases, as well as comprehension. Today we learnt the difference between Iron Sulphide & Iron Sulphate. Iron Sulphide is formed when Sulphur is chemicaly combined with Iron-----a black solid (FeS). Iron Sulphate is Iron, Sulphur, Oxygen chemically combined together-----a blue solid (FeSO4).
