The correct option is C.
The issue of disposal of waste of nuclear power plants has been a controversial issue for long because of the hazardous effects which these wastes have on human health and the environment. Most of the waste are usually long lived radioactive wastes which can remain active for a very long time and which have detrimental effect on both the environment and the human health.<span />
If the specific rotation of (r)-2-butanol is −13.5° then
the specific rotation of (s)-2-butanol is simply the opposite in sign 13.5°. In
a 3:1 mixture of (s):(r) 2-butanol, 75% is (s) while 25% is r, so the specific
rotation of the mixture is:
mixture rotation = 0.75 * (13.5°) + 0.25 * (- 13.5°)
<span>mixture rotation = 6.75°</span>
Answer:
235k
Explanation:
To solve this problem, we will use the general gas equation.
In its simplest form, the general gas equation can be represented as follows:
P1V1/T1 = P2V2/T2
P1 = 700mmHg
V1 = 760ml
T1 = 40 degrees Celsius = 40 + 273.15 = 313.15K ( conversion into standard temperature unit)
P2 = 1.25 atm
We have to covert this into the same unit as the first pressure.
760mmHg = 1atm
x mmHg = 1.25 atm
x = 1.25 * 760 = 950mmHg
V2 = 420ml
T2 = ?
Now, rearranging the equation will yield:
T2 = P2V2T1/P1V1
T2 = 950 * 420 * 313.5/700 * 760
T2 = 235.125K or -38.025 degrees celcius
