If gas is truly to be classified as a form of matter this means it can be measured. What form of gas can be measured?

Answers

Answer:

Gas is sometimes measured in cubic feet at a temperature of 60 degrees Fahrenheit and an atmospheric pressure of 14.7 pounds per square inch. Gas production from wells is discussed in terms of thousands or millions of cubic feet (Mcf and MMcf). Resources and reserves are calculated in trillions of cubic feet (Tcf).

Answer:

A dry gas, that is a natural gas, is the form in which gas can be measured.

And gas is measured in cubic meter, that is, it's volume is measured and the size of gas can be determined.

with examples of amino acids, explain the type of isomerism that exists in amino acids.​

Answers

Answer:

All amino acids are stereoisomers with the exception of glycine (because it has no chiral centers) and the two types are enantiomers and diastereomers

Explanation:

Not sure how in depth you need but the most fundamental categories are:

Enantiomers: non superimposable images which means that they cannot be placed on top of one another and look perfectly identical and instead are structurally the same but flipped in the opposite direction. An example being D-alanine and L-alanine.

Diastereomers: The molecules are superimposable which means they have an identical structure that will look the same placed on top of one another however, the compounds attached to the structure are placed in different orders an example being, L-isoleucine and D-allo-isoleucine (compounds in same place but isoleucine has two hydrogens positioned forward while allo-iso have one positioned forward and one positioned in the back)

The common type of isomerism among amino acids is the optical isomerism.

Isomerism refers to a situation in which there are two or more compounds that have the same molecular formula but different structural formulas. When two compounds have the same molecular formula but different atom to atom connectivity, they are called stereoisomers. Stereoisomers that are mirror images of each other are called enantiomers.

The common type of isomerism among amino acids is the optical isomerism. The optical isomers of alanine are shown in the image attached.
