Maximum volume question?!
So why is the answer C 50cm3
Original post by Adorable98
So 50cm3 of CO2 react with 25cm3 of O2 but oxygen cant react with all the CO2, so the volume produced must be 25cm3?!
So why is the answer C 50cm3

Look at what you have written and RTQ

All gases regardless of the size of the molecule take up the same space at the same conditions. In the reaction, 2 moles worth of anything takes up 50cm^3
That is not correct. I know what you are trying to say but I would not give you marks in an exam for writing that. You must be very careful with your wording.
For gases 2 moles worth of any gas takes up 48,000 cm3 under the standard conditions used.
One of the many issues that a lot of science students have is not writing technically correct answers. Using words like ions, molecules, intermolecular etc interchangeably in describing chemical bonding is a perennial example.

Okay well 2 moles worth relative in the molar ratio.

How about:
The mole ratio of CO to CO2 in the balanced equation is 1:1. Equal volumes of gases at stp contain the same number of moles. Therefore, 50 cm3 of CO produces 50 cm3 of CO2.
