What is the difference between a purine and a pyrimidine?
GalinKa [24]

Answer: Adenine and guanine are the two purines and cytosine, thymine and uracil are the three pyrimidines. The main difference between purines and pyrimidines is that purines contain a sixmembered nitrogencontaining ring fused to an imidazole ring whereas pyrimidines contain only a sixmembered nitrogencontaining ring. They both are types or categories of nitrogen containing bases present in nuclei acids of DNA and RNA.

Purines are 2 Ring or Carbon Ring, Nitrogen containing bases. That consist of these 2 rings next placed next to each other. These examples include - Adenine and Guanine.

Pyrimidines are 1 or single Ring Nitrogen containing structures. There are 3 nitrogenous bases that are categorized as pyrimidines. Cytosine, Thymine, and Uracil.

How many valence electrons do the halogens possess? group of answer choices
jok3333 [9.3K]

The valence electron does the halogens possess are 7

  • Valence electrons are found in the outermost energy level of an atom
  • They are involved in the formation of chemical bonding with other atoms.
  • The halogens elements are found in group 17 on the periodic table
  • The halogens include fluorine, chlorine, bromine, iodine and astatine.
  • They have seven valence electrons, so they are extremely reactive as they only need one more to fill their outer shell.
  • By octet rule we can say that the electron with 8 outer most shell is full and stable.

Hence the halogens posses 7 valence electron

almond37 [142]

Answer:

D

Explanation:

The formula for calculating kinetic energy is 1/2mv^2, where m is the mass and v is the velocity or speed of the object. Since all of the balls have the same mass, the one with the highest speed or velocity will have the highest kinetic energy. Hope this helps!

What is the volume (in liters) of a 5.98 gram sample of O2 at STP?
borishaifa [10]

Answer:

4.186 L

Explanation:

Using the pv=nrt equation and converting the grams of O2 into mols. After finding the number of mols by dividing 5.98 by 32 (2*the atomic weight of O) you plug that into the equation. So then you have 1*V=.186875*.08206*273 then you rearrange the equation to solve for v and get 4.186 L
