According to the developed chromatography plate proven beneath, what's the approximate Rf
price of aspartic acid?
Zero.20
Which of the following statements does NOT successfully describe the dehydration of malic acid
to fumaric acid and maleic acid?
The response is stereospecific.
What sort of practical institution is fashioned whilst aspartic acid reacts with any other amino
acid to form a peptide bond?
An amide institution.
,We have an professional-written solution to this trouble!
If 2-pentanol replaces 1-pentanol inside the reaction proven in Figure three, the price of
substitution is much less due to the fact:
There is more steric hassle at the 2-function of two-pentanol than at the 1-position of
1-pentanol.
If Reaction 2 (Figure 4) is repeated with HCl and the compound shown underneath, which of the
subsequent compounds is NOT an instantaneous product (without rearrangement)?
A.
If a solution containing the compounds shown in Figure four, is injected into a gasoline-liquid
chromatograph, the first top observed inside the gc trace is due to which compound?
2-methyl-2-butene.
This is an Organic Chemistry question that falls underneath the content category "Separation
and purification strategies." The solution to this question is B because 2-methyl-2-butene will
show off the lowest molecular weight and also the weakest intermolecular forces of appeal. This
substance will therefore migrate the quickest and be the first peak in the gasoline
chromatograph (gc) trace. It is a Scientific Reasoning and Problem Solving question due to the
fact you're requested to bring collectively concept and observations to draw a conclusion.
What is the fabricated from the response of Compound 1 (proven beneath) with HBr by way of
the pathway shown in Figure 3?
(S)-1-bromo-1-deoteriopentane
Acetic acid and ethanol react to shape an ester product as proven below.
In figuring out which reactant loses the -OH group, which of the following isotopic substitutions
could be maximum beneficial?
Replace the hydroxyl oxygen of ethanol with O-18.
A person, whose eye has a lens-to-retina distance of two.0 cm, can only without a doubt see
gadgets which are closer than 1.0 m away. What is the power (S) of the individual's eye lens
(Note: Use the skinny lens formulation: 1/O + 1/I = S)
51 D.
This is a Physics query that falls below the content material class "How mild and sound engage
with be counted." The answer to this question is C because the energy of the attention lens is
identical to the inverse of the focal length of the attention lens. Its numerical fee is given with the
, aid of (1 m)-1+(0.02 m)-1=1 D+50 D=51 D. It is a Knowledge of Scientific Concepts and
Principles query because you are requested to use mathematical equations to solve troubles."
Remember that the unit is m.
Which statement efficiently describes how enzymes have an effect on chemical reactions?
Stabilization of:
The transition country modifications the activation electricity of the response.
Which of the following will lower the percentage ionization of one.0 M acetic acid, CH3CO2H
(aq)?
Adding focused HCl (aq)
When the contemporary inside the micro-robot's circuit will increase and the resistance of the
circuit remains steady, the voltage of the circuit:
Increases.
We have an professional-written option to this hassle!
Knowing that the rate of mild within the vitreous humor is 2.1 x 10^eight m/s, what is the index of
refraction of the vitreous humor? (Note: The pace of mild in a vacuum is 3.Zero x 10^8 m/s)
1.Four
The depth of the radiation emitted by using the oxygen sensor is directly proportional to the:
quantity of photons emitted.
We have an expert-written option to this problem!
What is the energy of photons emitted via the LED at a frequency of 610 THz? (Note: h = 6.6 x
10^-34 Js)
4 x 10^-19 J
What is the connection among Pp, PMPA, and Pd
Pp = 3PMPA - 3Pd
What percent of atmospheric strain is the heart beat stress of a healthy grownup?
6%
forty five mmHg/760 mmHg = 6%.
