Answer:
The Fischer Projection formula of D-glucose is as shown in the attachment below.
The chiral centre that determines its name is the last carbon from the carbonyl group, C-6
Explanation:
Fisher projection formulas are used to show sugars in their open chain form. In a Fischer projection, the carbon atoms of a sugar molecule are joined vertically by solid lines, while carbon-oxygen and carbon-hydrogen bonds are joined horizontally using solid lines as well.
The horizontal bonds project out of the plane of the paper or screen towards the reader whereas vertical bonds project behind the plane of the paper or screen, away from the reader.
Glucose is an aldose sugar with two different optical isomers or enantiomers, D-glucose and L-glucose. The designation D- or L- depends on the configuration of the chiral or asymmetric carbon most distant from the carbonyl carbon of glucose. If the chiral carbon has the same configuration as D-glyceraldehyde, that the -OH roup on the right side of the carbon and -H group on the left, it is snamed D-glucose. However, if the chiral carbon has the same configuration as L-glyceraldyde, that is with the -OH group on the right and the -H group on the right, it is named L-glucose

Answer:
0.20 moles of Pb(CH3COO)4
Explanation:
89g Pb(CH3COO)4 x 1 mol Pb(CH3COO)4 / 443.376 g Pb(CH3COO)4
= 0.20 moles of Pb(CH3COO)4
Answer:
Valence electrons are involved in Reaction B but not in Reaction A.
Explanation:
The description of reaction A in which protons are lost or gained by the atom of the element is a nuclear reaction. In nuclear reactions, the nucleons which are the protons and neutrons drives the reaction. No valence electrons in the orbiting shells are involved in this kind of reaction. During this type of reaction, an atom changes it identity to that of another.
Reaction B in which no identity change occurs is a chemical reaction. In chemical reactions bonds are formed by the atoms using the valence electrons that orbits round the central nucleus. The atoms remain the same but it chose to attain stability and an inert configuration by losing or gaining electrons.
