Thursday, September 22, 2011. Her answers are well-written and reader-friendly. She provides accurate and informative answers. However, for question 4ii) and 5i), the question is asking for the ionic equations. But both her answers are in chemical equations. Her answers are short and straightfoward. For question 1, zinc hydroxide , ZnOH. For question 5, it would be better in she includes "add until there is excess solid". So that it's able to filtrate. For question 3iii), it is supposed to be Iron (II).
