What is the structure formula of disulfide oil?
Disulfide oil is composed of two hdrocarbon molecules tied together by two sulfur atoms. The general formula is RSSRWhere R is any hydrocarbon, and includes the appropriate number of hydrogens to complete the hydrocarbon.
What term describes the class of molecules that includes starch and glycogen?
carbohydrates
What diatomic molecules is joined by a double covalent bo nd?
This category includes all of the following, and there may be other: O2, CO, and NO.
Is everything made out of molecule's?
Not really. In part, this depends what you include in "everything". Most of the normal matter around us is made out of molecules. This includes solids, liquids, and gases. But please note that:* Some matter consists of individual atoms. "Molecules" are understood to have 2 or more atoms in a group. This includes most of the matter in stars - there it is too hot for the atoms to group to molecules.* Empty space is not "made up of" either atoms or molecules.* For every kilogram of normal matter in the Universe, there are at least 5 kilograms of some strange "dark matter". Nobody really knows what it is made of, but it's definitely not atoms or molecules.* Then there is the even stranger "dark energy" - there's even more of that in the Universe.* Light is made up of photons, not molecules or atoms.
What types of elements form compounds that consist of molecules?
Molecules are mostly made of non metals. Particularly in organic chemistry, we have carbon, oxygen, hydrogen, nitrogen, phosphorus, and sulfur as the main components, and they are all non metals. Metals are also part of organic chemistry and they are even part of molecules at times, for example, hemoglobin includes iron, but in most cases the metals appear in the form of ions, rather than molecules.
What is hydrated salt?
A hydrated salt is a compound that includes some water molecules when it crystallises. For example: Copper(II)sulfate can take 5 moles of water per mole of the salt on crystallization, Sodium acetate can add 3 and Calcium chloride up to 6. Normally on heating these hydrated salts can release the water (in steps) until all the water evaporated. The now anhydrous salts (without water) can re-attract water molecules for which they are used as drying agents (commonly used in laboratories are Sodium sulfate, Calcium chloride or Magnesium sulfate to dry organic solvent phases)
Group of molecules that includes thymine and cytosine?
A group of molecules that includes thymine and cytosine is pyrimidines
Is constant speed constant velocity?
No. Velocity includes a direction vector, which speed does not have.
Lowest level of organization that includes atoms and molecules?
The lowest level of organization that includes atoms and molecules is the chemical level. This is the level that maintains life.
What is the structure of flagella?
The structure of flagella includes the flagellar protein, flagellar motor, and hook. It also includes the flagellar filament and cap.
Which group of organic molecules includes enzymes?
Proteins
What actors and actresses appeared in The Constant Wife - 1933?
The cast of The Constant Wife - 1933 includes: Lionel Belmore
What is the beta and gamma phosphate?
This is referring to the structure of nucleotide tri-phosphates. The structure of these molecules includes three phosphate groups. The first phosphate attached to the nucleotide (usually adenosine or guanine) is called the alpha phosphate. The second is called the beta, and the third the gamma. They are named after the first three letters of the Greek alphabet.
