Complex organic molecules whose name means many units?
Complex organic molecules whose name means many units are called polymers. These are substances having a molecular structure that is made up of similar units bonded together.
What type of molecular movement is it if movement of molecules is against the concentration gradient from low to high through protein pumps?
Active Transport
If the yellow molecules have a molecular mass of 25 amu what is the molecular mass of the blue molecules?
36amu
Would ionic or covalent molecules use the molecular formula Why?
Covalently bonded compounds are characterized by a molecular formula, because such compounds exist in the form of discrete molecules, all of the atoms of which move together as kinetic-molecular units. Ionically bonded compounds do not have molecules in this sense: Their compounds are made up of at least two kinds of ions, one positive and the other negative, and the ions in these compounds can move separately as kinetic-molecular units: If a positive ion is separated from the particular negative ion with which it was most closely associated initially in a fluid mixture, usually a solution in an ionizing solvent, of both kinds of ions, another negative ion with the same properties is always close by.
What is the basis of molecular sieve chromatography?
The purification in molecular sieve chromatography is dependent on the size of the molecules. The small molecules will enter into pores of gel while large molecules will be excluded from the pores.
What are the molecular units of fat molecules?
Fatty acid molecules and glycerol molecules.
What are the smallest units of covalent molecular compounds called?
Molecules
A chemical compound whose simplest units are molecules?
Molecular compound
Which high molecular weight substances are made up of repeating units of these molecules?
starch and cellulose
Complex organic molecules whose name means many units?
Complex organic molecules whose name means many units are called polymers. These are substances having a molecular structure that is made up of similar units bonded together.
What type of molecular movement is it if movement of molecules is against the concentration gradient from low to high through protein pumps?
Active Transport
What is the unit of molecular refractive index?
I assume "molecular refractive index" refers to "the refractive index of a group of molecules". In this case, you just use the units for a refractive index - i.e., a dimensionless number.
What is the molecular formula of sodium bicarbonate?
NaHCO3. Note that since this compound has ionic bonds, it does not strictly have molecules but instead has "formula units.
If the yellow molecules have a molecular mass of 25 amu what is the molecular mass of the blue molecules?
36amu
What are macromolecules and how are the categorized?
Large molecules with high molecular weight low solubility and complex organization. eg-protein nucleic acid lipid polysaccharide
What are small molecular units joined together in large molecules called?
Macromolecules.
What smaller molecules make protein molecules?
Smaller molecules called amino acids make protein molecules.
