Combustion:
Conservation of Mass
Incomplete and Complete Combustion
your answer is well‐structured
you’ve tried hard to use a range of scientific or technical words
you’ve tried to make sure that you’ve spelled everything correctly.
Here is an example:
“It is quite easy to send people to the Moon, as it is not far away. Europa is much further. It would take many years to get there, so the spacecraft would need to take more food and might be too big to take off! It is possible that this could be solved by the people growing their own food on the journey. The spacecraft would also need enough oxygen to keep the people alive, as there is no oxygen in space. This would all cost a lot, so it would be difficult to imagine this project happening. Finally, we have already sent unmanned satellites out to this part of our Solar System, so perhaps we should use this type of project in the future to gather more information. This would be better than sending people out on a dangerous and long journey.”
