Nat2105 [25]2 years ago
8 0

Answer:

CH2

Explanation:

The empirical formula gives the lowest whole number ratio of the elements. In this case, both subscripts can be divided by 20, hence CH2.

How many Joules of heat would be required
mote1985 [20]

Heat would be required  : 1,670 J

<h3>Further explanation</h3>

Given

mass of H₂O=5 g

Required

Heat to melt

Solution

The heat to change the phase can be formulated :

Q = m.Lf (melting/freezing)

Lf=latent heat of fusion

The heat of fusion for water at 0 °C : 334 J/g

Input given values in formula :

\tt Q=5\times 334=\boxed{\bold{1,670~J}}

Photochemical chlorination of 1,2-dibromoethane gives a mixture of two stereoisomers of C2H3Br2Cl. Write their structural formul
Sever21 [200]

Answer:

Enantiomers

Chiral

Yes they will be formed in equal amount.

Explanation:

The Two possible stereo isomers are formed due to generation a chiral center in the molecule.

There will be a carbon with all the four groups different.

The two isomers will be called as enantiomers, which are non super-imposable mirror image of each other.

They are named as "R" or "S'" based on the selection rule.

The IUPAC names are also given in the figure.

The two isomers will be formed in equal amount as during photochemical chloriantion of a compound free radicals are generated (which are trigonal planar) and the other radical may attack from either side (front side or back side) giving the two stereo-isomers.

Consider the process of diluting 1.2 M NH4Cl solution to prepare 1.4 L of a 0.25 M NH4Cl solution. Determine if each of the foll
stepan [7]

Answer: True the dilution formula is a balanced of mole of the solute..

Explanation:

M1V1 = M2V2

When M1= 1.2M, M2= 0.25M V2= 1.4L and V1= ?

Then V1= 0.25*1.4/1.2

= 0.29

This indicate that 0.29L of the 1.2M NH4Cl will be dilluted to 0.25M in 1.4L of the solution....

The mole number of the solute remain constant

After completion of the citric acid cycle, most of the usable energy from the original glucose molecule is in the form of ______
GaryK [48]

After completion of the citric acid cycle, most of the usable energy from the original glucose molecule is in the form of B. ATP

The most basic kind of sugar, monosaccharides only have one kind of sugar molecule. The simplest sugar is glucose, which is also your body's primary energy source. In tests to determine blood sugar levels, sugar is measured. Fructose and galactose, two more monosaccharides, are converted into glucose via metabolism ( 1 , 2 ). For instance, ATP is necessary for both breathing and keeping your heart beating. As well as assisting in the synthesis of lipids and nerve impulses, ATP also facilitates the entry and exit of certain molecules from cells. Even some living things, including bioluminescent creatures like jellyfish and fireflies, use ATP to create light!
