Answer:
0.59
Explanation:
Is 0.59 because you are dividing 35.0g by 58.5 which will than give you 0.59
Answer:
![\textbf{ \huge\boxed{ \sf ETHENE}}](https://tex.z-dn.net/?f=%20%5Ctextbf%7B%20%5Chuge%5Cboxed%7B%20%5Csf%20ETHENE%7D%7D)
Explanation:
As the above statement says two carbon atoms are bonded to each other with double bond, the suffix used for double bond is -ene & the prefix for two carbon atoms is eth- & it says four Hydrogen atoms are attached to carbons, 2 Hydrogens to each carbon above & below.
When we draw the structural formula it comes out that the molecule is ethene.

Answer:
(a) The coefficient of performance of an irreversible refrigeration cycle is always less than the coefficient of performance of a reversible refrigeration cycle when both exchange energy by heat transfer with the same two reservoirs.
Explanation:
According to the Kelvin–Planck statement of the second law of thermodynamics ,it is not possible to construct a device which operates in cycle and does not produce effect on the environment than the production of work.
We know that
Coefficient of performance is the ratio of desired effect to the work input in a cycle.
Given all option is correct but most appropriate option is a.
So the option a is correct
(a) The coefficient of performance of an irreversible refrigeration cycle is always less than the coefficient of performance of a reversible refrigeration cycle when both exchange energy by heat transfer with the same two reservoirs.
