Answer:
Another name for ethanol can be ethyl alcohol, drinking alcohol or commonly called as alcohol.
Explanation:
The Ethanol is a simple alcohol which responds to this formula C2H6O.
You can also writes it as C2H5OH and as CH3-CH2-OH.
It is the principal active ingredient found in alcoholic drinks (for example in beer,vine,whisky,etc).
It is a volatile,flammable and colorless liquid.
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).
Regards.
Answer:
Which phrase best describes wave motion? Movement of energy through space or a medium.
Explanation:
Answer option A.
Answer: 360 minutes are required for 20 percent of a sample of cyclopropane to isomerize topropane.
Explanation:
Half life is the amount of time taken by a radioactive material to decay to half of its original value.
As the units of rate constant is , the reaction follows first order kinetics.
Expression for rate law for first order kinetics is given by:
where,
k = rate constant =
t = time for decomposition = ?
a = let initial amount of the reactant = 100
x = amount decayed =
a - x = amount left after decay process = 100-20= 80
Thus 360 minutes are requiredfor 20 percent of a sample of cyclopropane to isomerize topropane.
