Answer:
alkenes and alkynes are considered as unsaturated hydrocarbons because they are capable of reacting with hydrogen in the presence of a catalyst to form a saturated hydrocarbon (alkanes)
Explanation:
A saturated compound contains a chain of carbon atoms joined by single bonds, with hydrogen atoms attached to each carbon atom.
Propane for example, CH₃-CH₂-CH₃.
It is saturated because all the carbon atoms holds maximum number of hydrogen atoms.
Alkenes such as Propene (CH₂=CH-CH₃) and alkynes like Propyne,
(CH₃-C≡C-H) are unsaturated because the central carbon atoms contain less number of hydrogen atoms than they possibly could.
The relationship between volume and pressure is described in the Gay-Lussac's law. That is,
P₁V₁ = P₂V₂
Substituting the known values,
(75 mL)(145 atm) = (500 mL)(P₂)
The value of P₂ is equal to 21.75 atm.
Visible photon has more energy than a microwave photon. A microwave oven pumps out 1,000 watts of energy or more by generating a whole bunch of photons. Your conventional oven actually puts out even more energy (3,000 watts for an electric, 5,000 for gas). Most of that is infrared, which has less energy than visible light but more than a microwave.Thus the answer is <span>shorter than visible light.</span>
I'm pretty sure the aswer is B.
