Answer:
The advantage of the compound light microscope over the dissecting microscope is the magnification power of the telescope. Compound light microscope magnifies from 40x up to 1,000x while dissecting microscope magnifies up to 40 x only. In this regard, more magnification power is advantageous to view smaller objects.
The answer is HCl, C3H6 and C2H5OH. Hydrochloric acid has the lowest boiling point among the three choices since it only has weak dipole-dipole and Van der Waal's forces between molecules which are much weaker than the forces of attraction present in propane and ethanol. Ethanol has the highest since the hydrogen bonding present in ethanol make it hard to break the bonds.
The alkali metals, which occupy group 1 of the periodic table. This is because the valence shells of these elements have only 1 electron, so easily form an ionic bond with a non-metal compound by donating this. A cation is formed by this donation, since there is one fewer electron orbiting the nucleus than there is in the atomic form - conversely an anion is formed when an atom gains an extra electron to become negatively charged.
Answer: 0.02 molecules
The mass of sodium chloride= 23+35.5 = 58.5g
No. Of moles= Molar mass of NaCI
1.17 divided by 58.5 = 0.02
Answer:
The correct answer is b types of glycosidic bond between the monomers.
Explanation:
HomoPolysaccharides differ from each other by the presence of different glycosidic linkage within their chemical structure.
For example
1 Starch contain glucose residues which are linked by alpha-1,4-glycosidic linkage.
2 In glycogen molecule the glucose residues are linked together by both alpha-1,4-glycosidic linkage and alpha-1,6- glycosidic linkage.
3 In cellulose the glucose monomers are linked together by beta-1,4-glycosidic linkage.
