Answer:

Gasoline

Explanation:

Pure Substance: are those having same type of atoms or molecules.

Compound: one or more atoms of the element combine to form a compound.

Mixture: is combination of one or more substances mix together.

Homogeneous Mixture: are those which are not distinguish by naked eye but can be separated into its components by physical means

Heterogeneous mixture: are those which can be distinguishing by naked eye and can be separated into its components by physical means.

So keeping in mind the above definitions

Table salt:

The chemical formula of table salt is NaCl and it a pure compound not mixture.

Gasoline:

Gasoline is mixture of hydrocarbon, It contains small hydrocarbons ranging from 4 Carbon to 12 Carbon per molecule. it is a homogeneous mixture.

Aluminum:

Aluminum is a pure substance that is made up of same kind of atoms. so it is an element and not mixture. Its symbol is Al

Carbon dioxide:

Carbon dioxide is a pure compound and its chemical formula is CO₂ and not a mixture.

So, the write option is Gasoline.

According to VSEPR theory, what is the shape of a molecule of CS2? A bent B trigonal-planar C tetrahedral D linear

goblinko [34]

Answer:

D linear

Explanation:

Valence electrons of carbon = 4

Valence electrons of sulfur = 6

The total number of the valence electrons = 4 + 2(6) = 16

The Lewis structure is drawn in such a way that the octet of each atom in the molecule is complete. So,

The Lewis structure is:

$: \ddot S :: C:: \ddot S :$

There is no lone pair involved, so, It is of type AB₂.

<em><u>According to the theory, the atoms will form a geometry in such a way that there is minimum repulsion and maximum stability. </u></em>

<em><u>So, it is of linear shape.</u></em>

q6- convert the fisher projection of the following amino acid into a line structure. label the chiral center on the line structu

Vera_Pavlovna [14]

Fisher projection is the representation of organic molecule in2-D without destroying the3-D stereochemical information.

<h3>What does a Fischer projection in organic chemistry mean?</h3>

A Fischer projection is a drawing technique used in organic chemistry to depict molecules in two dimensions while maintaining the three-dimensional stereochemical information regarding the absolute arrangement at chiral centers.

<h3>What sets the Fischer projection apart from the Haworth projection?</h3>

In contrast to Fischer projections, which are used to represent sugars in their open-chain form, Haworth projections are typically employed to represent sugars in their cyclic forms.

Which type of reactions form salts?

s344n2d4d5 [400]

Neutralization reactions are the reactions type which form salts.

Explanation:

Salts are formed by ionic bonds when the oxidation states of anions and cations are equal and have opposite signs. So one should be highly electronegative in nature and another should be highly electropositive in nature. So the electropositive element will be ready to give electrons and the electronegative element will be ready to accept all the electrons given by the electropositive element. As a whole the compound will be neutrally charged by adding of equal number of positively charged and negatively charged ions.

The reduction or addition of electrons will be occurring in cations and the oxidation or removal of electrons will be occurring in anions.

So the salt formation is based on neutralization reactions.
