8-4: Name the three-dimensional shape of this molecule. _double strand coiled into a double helix__

This reaction is exothermic, as heat is given out. This is because the amount reactant energy is more than the product energy the difference between this is ΔH, therefore some energy has been given out in the form of

AB is a compound made of two or more elements. A and B are individual elements or compounds.

a. atoms lose electrons if they have just one or two electrons in their valence shells; they gain electrons if they need just one or two electrons to complete the valence shell as in K+CL- __Ionic bonds_

Part 31. What enzyme catalyzes the formation of H2 CO3 from CO2 and H2O? (This enzyme also catalyzes the

Box on right illustrates the peptide bond resulting from the condensation of both the amino acids. The box on the left illustrates the separation of the hydroxide group from glycine and the hydrogen atom from valine.

I believe the type of reaction to have occurred to be a condensation reaction as H2O has been produced as a by-product.

| Combustion product reacted by becoming cold, dissolving, and no gas formation with an end product is clear colorless solution.

B) Covalent bonds bind the atoms to each other in an organic molecule (Open Learning Initiative, 2015, pg.63).

C6H12O6 + 6O2 → 6CO2 + 6H2O + 686 kilocalories of energy/mole of glucose oxidized

Since one s orbital combined with three p orbitals, the result is sp3. From these four new hybridized orbitals three will take part in a bonding. The fourth orbital has 2e while the other 3 orbitals contains only one electron. So when a bonding occurs, the 3 single orbitals bond with hydrogen’s electrons.

There may also be sections where the secondary structure is neither helix nor sheet. Then the structure is called a random structure, indicating that it folds in random directions. The amino acids in an alpha helix are arranged in a right-handed helical structure resembling a spring. The alpha helix is the most common form of regular secondary structure in proteins. The beta-sheet is the second form of regular secondary structure in proteins consisting of beta strands connected laterally by three or more hydrogen bonds, forming a generally twisted, pleated sheet. The beta-sheet is sometimes called the beta pleated sheet since sequential neighboring atoms are alternately above and below the plane of the sheet giving a pleated appearance. Turns are the third of the three "classical" secondary structures that serve to reverse the direction of the polypeptide chain. They are located primarily on the protein surface and accordingly contain polar and charged residues. However, they are not very common in discussions of protein structure today.

In element bonding or the elements electron placement, it is very important to take note of. This concept is important because when figuring out the location of the electrons, you can find out what needs to bond or exchange with other elements that it wants to. Also when finding out the electron placement of the element, this can show the properties of the element. This part of the atom that is capable of doing this is the valence orbital or valence shell. Another piece of important parts of a Lewis dot structure is the shape or geometric shape of the atom. In order to discuss and predict chemical properties, you have to understand at least the shape or figure of the atom. When you understand this concept, you can maybe learn about the element or the atom’s mass, electronegativity,
