Due tomorrow (Wednesday 13th) are answers to the questions on pages four to seven of this workbook:
Elements, Water and Organic Chemistry Questions.
The first three pages are worth having a go at too.
Last week's homework was to colour a periodic table to show the alkali metals, alkali Earth metals, transition metals, semi-metals, halogens and noble gases. You should also show how the reactivity of the elements in groups 1 and 7 varies up/down the groups.
Here is a periodic table to download if you don't have one.
The homework before that was a page of writing on the following:
"Describe how a hydrogen powered vehicle works, and evaluate the use of this fuel in vehicles such as cars."
