You can find number bonds worksheets for practicing at math aids. Their number bonds worksheet is great for testing children in their ability to solve number bonds problems.
There are two pi bonds.

two bonds and eight lone pairs
20 / 0.2 = 100. Therefore, the number that 20 is 20 percent of, is 100.

No, the total number of bonds in glucose is different from the total number of bonds in two pyruvic acid molecules. Glucose has more bonds as it is a larger molecule with more atoms compared to two molecules of pyruvic acid.
The national treasury holds a significant number of stocks and bonds. To be precise it holds 20 Trillion dollars.

There are two pi bonds.
It would take 19 peptide bonds to make a protein of 20 amino acids.

In a polypeptide chain made up of 20 amino acids, there are 19 peptide bonds that form between adjacent amino acids. Each amino acid (except the first one) contributes to the formation of a peptide bond with the preceding amino acid.

This is easy to figure out, and it doesn't even matter what isomer of pentane we're talking about: There are five carbons. Each carbon can form four single bonds. Therefore, there must be a total of 5x4 = 20 single bonds, no matter how we arrange the carbon skeleton. Some of those (specifically, four) will be carbon-carbon bonds, and the remainder (sixteen) will be carbon-hydrogen bonds.
You haven't stated any bonds, you have just given a list of elements. Those elements can form various compounds, some having ionic bonds and some having covalent bonds. Uranium can also form metallic bonds.
The number of covalent bonds an atom can form is determined by the number of valence electrons it has. Atoms will typically form covalent bonds by sharing electrons to achieve a full outer electron shell, following the octet rule (except for hydrogen and helium, which follow the duet rule). An atom can form as many covalent bonds as needed to fill its valence shell.
