Why do densities of haloalkanes decrease when the size of alkyl group increases?

Chemistry
1 answer:
Verizon [17]3 years ago
8 0

Answer:

Here's what I get.

Explanation:

Your argument makes sense. For example, the density of C₅H₁₂ is about 0.63 g/mL, and it increases gradually to a limit of about 0.83 g/mL.  

With the lower alkyl halides, the halogen atom is the major contributor to the mass of the molecule. The density of chloromethane is 2.2 g/mL.

As you increase the number of C atoms, the Cl atom becomes a smaller part of the molecule. The alkyl halide becomes more like an alkane.

By the time you have reached four C atoms, the density has reached a limiting value of about 0.89 g/mL.

Salt is the product formed by a reaction in which _______ atoms of an acid are replaced by the atoms of a metal.
UkoKoshka [18]
<span>Salt is the product formed by a reaction in which the hydrogen atoms of an acid are replaced by the atoms of a metal. The salt is formed as a result of the neutralization of the acid by base, that is the metal or positive ion replace the hydrogen ion in the acid. For instance: NaO + H2SO4 = NaSO4 + H2O. In this example, Na [sodium] has replaced the hydrogen in H2SO4, thereby forming the salt NaSO4.</span>

A scientist is conducting a Sanger's sequencing experiment to determine the number of polypeptides present in an oligomeric prot
seropon [69]

Answer:

Depends on molecule.

Explanation:

The number of the polypeptide chains present in the oligomer depends on the molecule. Some molecules have more polypeptide chains whereas some of them have less polypeptide chains. For example, Hemoglobin is a oligomer that consists of four Polypeptide Chains, two of these Polypeptide Chains are α-globin molecules, each comprise of 141 amino acids, and the other two are (β, γ, δ, or ε) globins, each consist of 146 amino acids.

What is the chemical formula for 8.6 mol of sulfur and 3.42 mol of phosphorus
adell [148]

The chemical formula for the compound containing 8.6 mol of sulfur and 3.42 mol of phosphorus is P₂S₅

<h3>How do I determine the formula of the compound?</h3>

From the question given above, the following data were obatined:

  • Sulphur (S) = 8.6 moles
  • Phosphorus (P) = 3.42 mole
  • Chemical formula =?

The chemical formula of the compound can be obtained as follow:

Divide by their molar mass

S = 8.6 / 32 = 0.26875

P = 3.42 / 31 = 0.11032

Divide by the smallest

S = 0.26875 / 0.11032 = 2.44

P = 0.11032 / 0.11032 = 1

Multiply by 2 to express in whole number

S = 2.44 × 2 = 5

P = 1 × 2 = 2

Thus, the chemical formula is P₂S₅

Question 20 (1 point)
romanna [79]

Answer:

A. The ratio of the element in glucose is different than in ethanol

Explanation:

The compounds given are;

      Glucose      C₆H₁₂O₆

     Ethanol         C₂H₆O

The two compounds given are different from one another. But they have the same elemental composition.

   Ethanol is made up of Carbon, hydrogen and Oxygen and so also, Glucose

Now,

  The number of atoms in both compounds are different;

                                   Number of atoms

                        C                             H                     O

Glucose           6                             12                      6

Ethanol            2                              6                       1
