<u>Answer:</u> The new volume of the gas will be 0.233L.
<u>Explanation:</u>
To calculate the new volume of the gas, we will use the equation given by Boyle's Law.
The above law states that the pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.
Mathematically,
(At constant temperature and number of moles)
or,
where,
are the initial pressure and volume of the gas.
are the final pressure and volume of the gas.
We are given:
Putting values in above equation, we get:
Hence, the new volume of the gas will be 0.233L.
The formula for the molecular formula is molar mass/ empirical formula
So, the empirical formula of C3H7 is equal to C*3 + H*7 which is equal to 12*3 + 7. Then use the molecular formula = 86 / (12*3+7) = 2
Therefore, the molecular formula is 2 times the empirical formula which is C6H14.
Explanation:
We calculate the amount of carbon fixed as follows.
= kg
= -1273.1 kJ/mol
= -393.5 kJ/mol
= -285.8 kJ/mol
Hence, total reaction will be as follows.
=
= 2802.7 kJ/mol
Therefore, calculate the number of moles of fixed carbon as follows.
=
=
Thus, we can conclude that the annual enthalpy change resulting from the photosynthetic carbon fixation over the land surface is .
