Treatment of (S)-( )-5-methyl-2-cyclohexenone with lithium dimethylcuprate gives, after protonolysis, a good yield of a mixture containing mostly a dextrorotatory ketone A and a trace of an optically inactive isomer B. Treatment of A with zinc amalgam and HCl affords an optically active, dextrorotatory hydrocarbon C. Identify compounds A, B, and C, including stereochemical configurations. Be sure to explicitly draw H and both wedge/dash bonds at any configuration center.

Final answer:

Treatment of (S)-( )-5-methyl-2-cyclohexenone with lithium dimethylcuprate followed by protonolysis produces dextrorotatory ketone A and a trace of isomer B. Compound A can yield optically active, dextrorotatory hydrocarbon C when treated with zinc amalgam and HCl.

In the nuclear transmutation represented by 168o(p, \alpha) 137n, the emitted particle is ________.

Answers

Answer is: the emitted particle is an alpha particle.

Nuclear reaction: ¹⁶O + p⁺→ ¹³N + α (alpha particle).
Alpha decay is radioactive decay in which an atomic nucleus emitsan alpha particle (helium nucleus) and transforms into an atomwith an atomic number that is reduced by two and massnumber that is reduced by four.
When oxygen-16 gain one proton, atomic mass is 17, but when lose alpha particleatomic mass reduces by four to 13.

How much energy in joules does it take to raise the temperature of 255g of water by 12.5C

Answers

Energy in a system can be calculated by multiplying the given mass to thespecific heat capacity of the substance and the temperature difference. It isexpressed as follows:

Energy = mC(T2-T1)
Energy = 255(4.184)(12.5)
Energy = 13336.5 J

Answer: The amount of energy required to raise the temperature is 13323.75 joules.

Explanation :

The amount of energy required to raise the temperature can be calculated as follows.

$q = m* C* \bigtriangleup T$

where,

q = heat energy

m = mass of water

C = specific heat

T = temperature

Remember that the specific heat of water is $4.18\left ( (J)/(g^\circ C)} \right )$ .

Therefore, putting the values in the above equation as follows.

$q = m* C* \bigtriangleup T$

$= 255 g * 4.18 \left ( (J)/(^\circ C)} \right )* 12.5^oC$

= 13323.75 joules

So, the amount of energy required to raise the temperature is 13323.75 joules.

Which of the following statements is true with regard to transverse and longitudinal waves?Group of answer choices

Both transverse waves and longitudinal waves have motion parallel to velocity.

Both transverse waves and longitudinal waves have motion perpendicular to velocity.

Transverse waves have motion parallel to velocity, while longitudinal waves have motion perpendicular to velocity.

Transverse waves have motion perpendicular to velocity, while longitudinal waves have motion parallel to velocity.

Answers

The true statement is that Transverse waves have motion perpendicular to

velocity, while longitudinal waves have motion parallel to velocity.

What is a wave?

This is a disturbance which travels through a medium and transports

energy in the process.

Transverse waves have motion which are perpendicular to the velocity

while the longitudinal waves move in the direction of the velocity which is

why they are regarded as being parallel to each other.

Answer:

D (The last answer)

Explanation:

In a transverse wave, particles oscillate perpendicular to the direction of wave motion.

In a longitudinal wave, the oscillations of particles are parallel to the direction of propagation.

Challenge question! One of the things hedoesn't mention is in order to use E=hf,

be in JOULES. We have the energy in eV.
So this will be a two step question. First,

find the wavelength. Once you are done
with that, pick the correct answer below.
