Answer:
Each nucleotide, in turn, is made up of a nitrogenous base, a pentose sugar, and a phosphate.
Explanation:
Since benzene is a covalently bonded chemical, ions and ionic bonds have no bearing on it. Simply put, boiling will cause the molecules to split from one another and turn into a gas.
Benzene boils at a greater temperature than other hydrocarbons with comparable molecular sizes, at 80°C (pentane and hexane, for example). The increased boiling point is most likely caused by how simple it is to create transient dipoles involving the delocalized electrons. At 111°C, methylbenzene begins to boil. Pure benzene and pure toluene have normal boiling points of 80.1 C and 110.6 C, respectively. Due to fewer intermolecular interactions, benzene has a lower boiling point than toluene.

Answer:
Average atomic mass of uranium= 237.98 amu.
Explanation:
Given data:
Abundance of U²³⁴ = 0.01%
Abundance of U²³⁵ = 0.17%
Abundance of U²³⁸ = 99.28%
Average atomic mass = ?
Solution:
Average atomic mass of uranium = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass) +(abundance of 3rd isotope × its atomic mass) / 100
Average atomic mass of uranium= (234×0.01)+(235×0.71)+(238×99.28)/100
Average atomic mass of uranium= 2.34 + 166.85 + 23628.64 / 100
Average atomic mass of uranium= 23797.83 / 100
Average atomic mass of uranium= 237.98 amu.
Amino acids are categorized by their chemical properties on the basis of the sequence of side chain (R group).
<h3>What are amino acids?</h3>
Amino acids are known as the 'building blocks of the life' as they help in the formation of proteins inside the body.
Side chain of amino acids is specific in nature and are known by the name of R group, these R groups are attached with the alpha carbon atom. R groups characterizes below properties of the molecule:
- Shape
- Size
- Charge and
- Reactivity
Hence R group describes the chemical properties of amino acids.

Answer:
Explanation:
Hello.
In this case, given the described reaction, the formation of nitric acid turns out:
Since two hydrogen atoms are present at the reactants we balance it as follows:
In such a way, since there is a 1:2 mole ratio between water and nitric acid, the produced moles of nitric acid, turns out:
Best regards!
