Answer:
W=-37.6kJ, therefore, work is done on the system.
Explanation:
Hello,
In this case, the first step is to compute the moles of each gas present in the given mixture, by using the total mixture weight the mass compositions and their molar masses:
Next, the total moles:
After that, since the process is isobaric, we can compute the work as:
Therefore, we need to compute both the initial and final volumes which are at 260 °C and 95 °C respectively for the same moles and pressure (isobaric closed system)
Thereby, the magnitude and direction of work turn out:
Thus, we conclude that since it is negative, work is done on the system (first law of thermodynamics).

The answer is b. as a whole, the species is mutually beneficial to carry on each others traits and exist in the same ecosystem.
Answer:
Our energy supply comes mainly from fossil fuels, with nuclear power and renewable sources rounding out the mix.
The energy associated with an object's motion is called kinetic energy. Kinetic energy is the energy of motion. All moving objects have kinetic energy
Explanation:
I believe it is D. Hope this helps you!
Answer:
The least electronegative elements in the center of lewis structures because an atom in the central position shares more of its electrons than does a terminal atom. Atoms with higher electronegative are generally more reluctant to share their electrons.
