When you are writing formulae and equations, you need to write your answer in such a way that the computer will recognise your answer. Please following the following instructions:
- Separate all substances with a space (E.g. 4Na + 2O2 --> 2Na2O)
- No space between the stoichiometric number and the compound/ion/element
- The arrow must be formed like this --> It is two dashes and a greater than sign.
- Any charges must be placed in a round bracket, e.g. SO4(2-) for sulfate, H(+) for hydrogen ions, and e(-) for electrons.
- Do not put in state symbols unless asked.
Example: 2ClO3(-) + 12H(+) + 10e(-) --> Cl2 + 6H2O
One question will ask you to draw a diagram. Please draw it on paper, take a picture of it, send it to your computer, and upload it using the function. If you really want to draw it using your mouse, you can, but I definitely don't recommend it.
Your teacher will mark questions 7, 11, 12 and 13. These questions are written questions and a diagram.
