When studying atoms, scientists can ignore the
vekshin1

When studying atoms, scientists can ignore <u>the Gravitational</u> force between charged particles that make up  the atoms because it is many millions of times smaller than other forces in the atom.

Explanation:

Scientists can ignore the gravitational force because the gravitational force is considered to be negligible as compared to the other forces due to its smaller value.We all know that the gravitational force is directly proportional to the mass of an object which  result in  a small force value.When the value of this small force is compared to the value of the electrical force between protons and electrons in atoms the we can say that the electrical force is million times stronger than the gravitational force

Thus we can say that scientists can ignore <u>the Gravitational</u> force between charged particles that make up  the atoms because it is many millions of times smaller than other forces in the atom.

1-butanol yields 1-bromobutane in the presence of concentrated sulfuric acid and an excess of sodium bromide. CH3CH2CH2CH2OH (l)
Zanzabum

Answer:

The answer to your question is: yield = 56.27%

Explanation:

Data

             CH3CH2CH2CH2OH (l) → CH3 CH2CH2CH2Br

                18.54 ml 1-butanol            15.65 g of 1-bromobutane

% yield = ?

density = 0.81 g/ml

MM = 74 g  1- butanol

MM = 137 g 1-bromobutane

Process

Calculate mass of 1- butanol

              density = mass/volume

              mass = density x volume

              mass = 0.81 x 18.54

              mass = 15.02 g of 1-butanol

Theoretical yield

              74 g of 1- butanol -----------------  137 g of 1-bromobutane

              15.02 g of 1- butanol -------------   x

              x = (15.02 x 137) / 74

              x = 27.81 g of 1-bromobutane

% yield = experimental yield / theoretical yield x 100

% yield = 15.65 / 27.81 x 100

% yield = 56.28

Atoms or clusters of atoms that are covalently bonded to carbon and influence the behavior of organic compounds are known as
SVEN [57.7K]

Answer:

Functional groups

Explanation:

A functional group refers to an atom or cluster of atoms that are covalently bonded to carbon and influence the behavior of organic compounds.

There are several functional groups in organic chemistry that determine the properties of organic compounds.

For instance, in the compound CH3CH2CH2CH2OH, the functional group is the -OH group. The chemical and physical properties of this compound is largely determined by this functional group.
