Answer:
%DP=12.3% increment
Explanation:
The duration of a ten-year, 10 percent coupon bond when the interest rate is 10 percent is 6.76 years. What happens to the price of the bond if the interest rate falls to 8 percent?
We go by the formula.
As the calculation in tables(on the internet), the duration of a ten-year 10% coupon bond is 6.76 years.
......................................................................1
duration=6.76
di=change in interest=0.08-0.1
i=initial interest rate, 10%
Juxtaposing the parameters into the given equation
-6.76*(-0.18)/1.1
%DP=12.29
%DP=12.3% in approximation
Answer: The maximum wavelength of light for which a carbon-chlorine Single bond could be broken by absorbing a single photon is 354 nm
Explanation:
The relation between energy and wavelength of light is given by Planck's equation, which is:
where,
E = energy of the light = (1kJ=1000J)
N= avogadro's number
h = Planck's constant
c = speed of light
= wavelength of light
Thus the maximum wavelength is 354 nm
Percentage recovery gives us an idea of the amount of pure substance recovered after the chemical reaction. Percentage recovery can be more than 100 % or less than 100 %. Usually, in any experiment performed the weight percentage recovery will be less than 100. Percent recovery values greater than 100 show that the recovered compound is contaminated.
Amount of acetaminophen initially taken = 350 mg
Amount of acetaminophen obtained after recovery =185 mg
=
= 52.9%
