I need steps on how to do it and the actual answer because I am a beginner to chemistry . I know the balanced formula, I just dont know how to take it farther and find the grams of oxygen.

2C812 + 25O2 ---> 16CO2 + 18H2O is the balanced equation.

Thank you very much!!

I've heard the answers about more daylight, etc. But that doesn't wash - the hour change is for summer (British Summer Time), not for the winter, which is reset to GMT.

If you know the base angles of a trapezoid, and you know the length of each base, how can you find the length of the median, the line that connects the middle of each base, each base. For example, If one base angle is 33 and the other is 57, one base is 6 an the other is 10, how can I find the length of the line that connects the middle of each base together??
Please give a proof, and if possible, the angle that the line forms
