Answer:
1. Ionic bond
2. High melting point and high boiling point for ionic bonds while covalent bonds have low melting and boiling point.
3. The similarity is that ionic and covalent bonding lead to the creation of stable molecules.
4. 4Fe + 3O2 → 2Fe2O3
5. It uses the process of fission.
6. Fission involves the splitting of radioactive elements into smaller particles/compounds while Fusion involves combining of two or more atomic nuclei to form one or more different atomic nuclei and subatomic particles.
7. Nuclear power plants produce little to no greenhouse gas.
Nuclear power plants produce a large amount of energy for a small mass of fuel.
Nuclear is less expensive.
44g of CO2 can produce by the reaction of carbon with oxygen
Atoms are now not indivisible and and the elements are identical
The structural form of D-glyceraldehyde is shown in the picture. As you can see, the L-glyceraldehyde and the D-glyceraldehyde are isomers. The D-isomer has the OH placed at the right side of the structure. Thus, the right side, encased in a red box, is the structure for D-glyceraldehyde.
Really, both David and Susan are right; they were using the term "pure" in different ways. David likely meant "pure honey" in the sense that the honey was not altered or had any additives. Susan used pure as in a "pure substance" in chemistry. Susan is also right, because honey is a medley of carbohydrates, proteins, amino acids, and vitamins and minerals. Chemically, honey is not a pure substance- it's a mixture.
