I’m so annoyed about the first calculation because I got 31 but then I thought it was at too big so I put 0.31 instead but hopefully they see that I did do 31 in the first place 🤣🤣


the answer was 0.031 as you had to convert to mg and dm^3

I said that through Fractional Distillation, different hydrocarbons in the crude oil mixture where separated through condensation when the hydrocarbons hit their boiling points. There are different chambers for liquids to leave through condensation for the gas to be collected. however, the boiling point's of the chambers decrease as you go up.

Last 4 marker this is as far as I got.
Sun is emitted as short wave radiation. It is absorbed as long wave infra red radiation. This is then absorbed by greenhouse gases, causing the earth to warm and the greenhouse effects. Things such as ice clads melting and a disruption in migration patterns are a result of this.


was this on the seperate paper or the combined
