How many GRAMS of carbon are present in 4.00 moles of carbon
dioxide, CO2?
How many MOLES of oxygen are present in 3.11 grams of carbon
dioxide?
How many GRAMS of oxygen are present in 9.82×10^22 molecules of
tetraphosphorus decaoxide?
12.2 Compression of Carbon Dioxide
Carbon dioxide (CO2) at 1 bar and 300 K enters a compressor
operating at steady state and is compressed adiabatically to an
exit state of 10 bar and 520 K. The CO2 is modelled as an ideal
gas, and the KE and PE effects are negligible. For the compressor,
determine
a) Work input [kJ/kg]
b) Rate of entropy production [kJ/kg?K]
c) The isentropic compressor efficiency
d) T-s diagram of isentropic and real process
You are given six samples of carbon dioxide (CO2) that are stored at different temperatures and at different pressures. Using the interactive activity showing the phase diagram of CO2, determine the phases of each of the samples and classify them according to which phase they are in. Keep in mind that the temperature and pressure are not to scale.
Drag the appropriate items to their respective bins.
How many rotational degrees of freedom are there in a carbon
dioxide (CO2) molecule? Under low pressure, CO2 gas heated up to
high enough temperature to excite its translational, rotational and
vibrational modes, (i) find its specific heats and (ii) compare the
specific heats from (i) and literature values at moderate
temperatures.
The amount of carbon dioxide in a gaseous mixture of CO2 and CO
can be determined by passing the gas into an aqueous solution that
contains an excess of Ba(OH)2, The CO2 reacts, yielding a
precipitate of BaCO3, but eh CO does not react. This method was
used to analyze the equilibrium compostion of the gas obtained when
1.77 g of CO2 reacted with 2.0 g of graphite in a 1.000 L container
at 1100 K. The analysis yielded 3.41...
Draw the orbital overlap diagram for bicarbonate CH2NH and give
perspective on the bonds using dashes and wedges. I am unsure on
how to use dashes and wedges.. how can you tell how far a bond
is?
