How do most diamonds get their color?

Chemistry
1 answer:
alina1380 [7]3 years ago
5 0

Answer:Most naturally-coloured diamonds are created when trace elements interact with the carbon atoms during the diamond's creation. The presence of chemical elements such as nitrogen, sulphur, and boron can colour diamonds in shades of yellow, green, and blue. ... Trace elements have never been found in pink diamonds.

in other words it depends on the heat of how it is made

Predict the carboxylic acid product of the following reaction:CH3COOCH2CH3ethyl ethanoate+H2OH+⟶carboxylic acid+CH3CH2OHethanolE
GaryK [48]

<u>Answer:</u> The IUPAC name of the carboxylic acid formed is ethanoic acid.

<u>Explanation:</u>

The basic rules for naming of organic compounds are :

  • First select the longest possible carbon chain.
  • The longest possible carbon chain should include the carbons of double or triple bonds.
  • The naming of alkane is done by adding the suffix -ane, alkene by adding the suffix -ene, alkyne by adding the suffix -yne and carboxylic acid by adding the suffix -oic acid.
  • The numbering is done in such a way that first carbon of double or triple bond gets the lowest number.
  • The carbon atoms of the double or triple bond get the preference over the other substituents present in the parent chain.

For the given chemical reaction, the equation follows:

CH_3COOCH_2CH_3+H_2O\rightarrow CH_3COOH+CH_3CH_2OH

When hydrolysis of ester takes place, it leads to the formation of an alcohol and a carboxylic acid.

So, when hydrolysis of ethyl ethanoate occurs, it produces ethanol and a 2- Carbon carboxylic acid named as ethanoic acid.

Hence, the IUPAC name of the carboxylic acid formed is ethanoic acid.

Chlorine (CI) can be found as an ion with a 1- charge. How does this happen?
Lesechka [4]

Answer:There are 18 electrons and 17 protons, so the chlorine atom has become a charged chlorine ion with a charge of negative one (-1). ... When it does, the sodium atom becomes a sodium ion with a charge of positive one (+1). Chlorine, as mentioned above, desperately wants an electron so it can fill its outer electron level.

Lithium forms compounds which are used in dry cells and storage batteries and in high-temperature lubricants. It has two natural
agasfer [191]

The naturally occurring isotopes of Li are Li-6 of mass 6.015121 amu and Li-7 of mass 7.016003 amu. The atomic mass of Li is 6.9409 amu, the percent abundance can be calculated using the following relation.

Atomic mass=m(Li-6 )×%(Li-6 )+m(Li-7 )×%(Li-7 )

Let the percent abundance of Li-6 be X thus, that of Li-7 will be 1-X, putting the values,

6.9409 amu=6.015121 amu\times X+7.016003 amu(1-X)

Or,

6.9409 =6.015121 X+7.016003-7.016003 X

Or,

X=0.075

Thus, 1-X=1-0.075=0.925

Thus, percent abundance of Li-6 is 0.075 or 7.5 % and that of Li-7 is 0.925 or 92.5%.

What word or two-word phrase best describes the shape of the fluoroform molecule?
Vlad [161]

Answer : The shape of the fluoroform molecule is Tetrahedral.

Explanation :

First we have to calculate the Hybridization of the molecule by formula,

\text{Number of electrons} = \frac{1}{2}[V+H-C+A]

where,

V = Number of valence shell electron in central atom

H = Number of neighboring monovalent atom

C = charge of cation

A = charge of anion

The central atom in this molecule is Carbon, it has 4 electrons in their valence shell.

The neighboring monovalent atoms are one Hydrogen atom and three Fluorine atom.

There is no charge of cation and anion on the given molecule.

V = 4

H = 1 Hydrogen atom + 3 fluorine atom = 4

C = 0

A = 0

By the above hybridization formula, we get

\text{Number of electrons}= \frac{1}{2}[4+4-0+0] = 4

The number of electron pair = 4

The number of lone pair = 0

The number of electrons is 4, this means that the hybridization is sp^{3} and the geometry of the molecule is Tetrahedral.

The geometry of the molecule is shown below.
