You are an isosceles triangle that has two equal sides and two equal angles.
When will two plus two equal five?
two plus two will never equal five you asses
A quantitative relation between two amounts?
ratio
What two numbers equal 185?
There are no two such numbers. 185 is equal to 185. No other number is equal to 185.
What is a recemate?
In chemistry, a racemic mixture is one that has equal amounts of left- and right-handed enantiomers of a chiral molecule. The first known racemic mixture, or racemate, was 'racemic acid', which Pasteur found to be a mixture of the two enantiomeric isomers of tartaric acid. A racemate is optically inactive: because the two isomers rotate plane-polarized light in opposite directions they cancel out, therefore a racemic mixture does not rotate plane-polarized light. In contrast to the two separate enantiomers, which generally have identical physical properties, a racemate often has different properties compared to either one of the pure enantiomers. Different melting points and solubilities are very common, but different boiling points are also possible.
What is the difference between racemic mixture and mesocompounds?
1:1 molar solution of two enantiomers is recemic mixture and it may be resolved into two parts by chemical means while mesoform is a pure substance and can not be resolved, but both these are optically inactive.
What is A number sentence stating that two amounts are equal?
An Equation is a number sentence stating that two amounts are equal
Can glycerol form any enantiomers?
Yes, it can. There are two glycerol enantiomers, depending on the position of OH group on the second carbon atom.
Why are enantiomers of biological interest?
Mainly because enantiomers have identical physical and chemical properties. However, the difference between two enantiomers can have tremendous impact, especially in biological systems, because many important biological molecules are chiral.
Can you give an example of a sentence using the word equal?
The two amounts were equal. In the eyes of the law both claims were determined to be equal. She mixed equal amounts of rice and water.
How is chiral resolution process?
The separation of a racemic mixture into two optically active forms (+ or −) is known as chiral resolution. Since diastereomers have different chemical and physical properties, they can be separated into corresponding enantiomers by chiral resolution. This method is called enantiomeric enrichment, and it is a process of continuously increasing the percentage of enantiomers until the enantiomeric excess finally approaches 100%./BOC Sciences
What is the difference between enantiomers and diastereomer?
There can be several structural formulas for a single molecular formula. These are known as isomers. Isomers can be defined as "different compounds that have the same molecular formula." There are mainly two types of isomers called constitutional isomers and stereoisomers. For example, C4H10 can have following constitutional isomers.Constitutional isomers are "isomers that differ because their atoms are connected in a different order." Stereoisomers are isomers that differ from the spatial arrangement of the atoms. Diastereomers and enantiomers are the two types of stereoisomers.DiastereomersDiastereomers are stereoisomers whose molecules are not mirror images of each other. For example, cis and trans isomers are Diastereomers.In the above two compounds, the connectivity of atoms is same. Both compounds have a carbon- carbon double bond. And for each carbon, a chlorine atom and a hydrogen atom is connected. Cis and trans molecules differ only from the way atoms are arranged in the space. That is, in cis isomer, both hydrogens are on the same side of the carbon double bond. But in the trans isomer, hydrogen atoms are on either side of the carbon double bond. And the two structures are not mirror images of each other. Therefore, they are Diastereomers. However, cis and trans molecules are not the only kind of diastereomers we can find.EnantiomersEnantiomers are "stereoisomers whose molecules are nonsuperposable mirror images of each other. " Enantiomers are only possible with molecules, which are chiral. Chiral molecule is the one that is not identical with its mirror image. For a molecule to be chiral, it should have one tetrahedral atom with four different groups attached to it. This carbon atom is known as a stereocenter. Chiral molecules make mirror images that are not superposable. So the molecule and the mirror image are said to be enantiomers. Following is an example of a compound that forms enantiomers.The enantiomers are named using the R and S system. So, according to the system the molecule on the right hand side is (S)-2-butanol, and the other one is (R)-2-butanol. Enantiomers don't have different boiling points, melting points, solubilities, different infrared spectra etc. All these chemical and physical properties of enantiomers are similar because intermolecular forces are similar in both isomers. They become separate only by their different behaviors towards the plane polarized light. That is, enantiomers rotate the plane of the plane polarized light in opposite directions. However, they rotate the light in equal amounts. Because of their effect on the polarized light, enantiomers are said to be optically active. The equimolar mixture of two enantiomers is called a racemic mixture. Racemic mixture doesn't show any rotation of the polarized light, therefore it is optically inactive.
