<span>Given in the question-
1 mole of cyclohexanol = > 1 mole of cyclohexene
Molar mass 100.16 g/mol
moles of cyclohexanol = .240 / 100.16= 0.002396 moles
Molar mass 82.143 g/mol
moles of cyclohexene formed @100 % yield = 0.002396
Molar mass 82.143 g/mol
mass of cyclohexene @ 100 % = .002396 x 82.143 = 0.197g
bur we have .138g
so % yield = .138 / .197 = 70.0 %
Ans- 70 percentage yield of cyclohexene.</span>
Explanation:
momentum increases with an increase in mass and velocity
The electromagnetic (EM) spectrum<span> is the range of all types of EM </span>radiation<span>. Radiation is energy that travels and spreads out as it goes – the </span>visible light<span> that comes from a lamp in your house and the </span>radio<span> waves that come from a radio station are two types of electromagnetic radiation. The other types of EM radiation that make up the electromagnetic spectrum are </span>microwaves<span>, </span>infrared light<span>, </span>ultraviolet light<span>, </span>X-rays<span> and </span>gamma-rays<span>. So it should be electromagnetic </span><span />
Answer:
The 95% confidence level is
Explanation:
If we can apply the central limit theorem, we can approximate this distribution to a normal distribution.
The confidence level (for n=1) is defined as
For a 95% confidence interval, according to the normal distribution, z=1.96.
Then we have:
