Answer:

from the pic:

$empirical \: formular : \: \: C _{2}H _{3}O _{2}$

since molar mass is 118.084 g/mol;

$(C _{2}H _{3}O _{2}) _{n} = 118.084 \\ C _{2n}H _{3n}O _{2n} = 118.084 \\(12 \times 2) _{n} + (1 \times 3) _{n} + (16 \times2 ) _{n} = 118.084 \\ 24_{n} + 3_{n} + 32_{n} = 118.084 \\ 59_{n} = 118.084 \\ n = 2$

${ \boxed{ \bf{molecular \: formular : \: C _{4}H _{6}O _{4}}}}$

It is an aldehyde with structure ( second pic )

katovenus [111]

Answer:

Ether

SN1 mechanism

Explanation:

The nucleophile in this reaction is CH3OH. It is a poor nucleopile. We already know that a poor nucleophile reacting with a tertiary alkyl halide often leads to the substitution product as the major product.

Also, the iodide ion is a good leaving group. This makes the SN1 substitution more likely yielding the ether as the major product as shown in the image attached.

<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2><h2>_____________________________________</h2><h2>Question no 1:</h2><h3>CATION:</h3>

Cation is the postively charged unit which is formed by the transfer of one or more electrons. It is attracted towards cathode thus it is called the CATION.

<h2>_____________________________________</h2><h2>Question no 2:</h2><h3>IONIC BOND:</h3>

Ionic bond is the type of bond which is formed between the positive and negative ions. It is mostly formed between the Metals (i.e. group 1 and 2) and Non metals (i.e. mostly group 7). The positive charge on metal is due to the loosing of electron and negative charge on non metal is due to accepting the electron.

<h2>_____________________________________</h2><h2>Question no 3:</h2><h3>POLYATOMIC ION:</h3>

A molecular ion is a covalently bonded set of two or more atoms, that can be considered to behave as a single unit, it also has a charge on it.

<h2>_____________________________________</h2><h2>Question no 4:</h2><h3>CONDUCTIVITY:</h3>

Conductivity is more in liquid than in solid because the conductivity is flow of electron and the movement is less in solid than liquids thus the solid has less conductivity. The liquid has more movement of molecules due to which there is more conductivity.

<h2>_____________________________________</h2><h2>Question no 5:</h2><h3>FORMULA UNIT: </h3>

Formula unit is a emperical formula used to express the ions in ionic compounds. It is the least whole number ratio of the ions present in the ionic compound.

<h2>_____________________________________</h2><h2>Question no 6:</h2><h3>CRYSTAL LATTICE:</h3>

Crystal lattice is the arrangement of atoms, molecules, or ions of a crystal in the form of a three dimensional space lattice.

<h2>_____________________________________</h2><h2>Question no 7:</h2><h3>ANION:</h3>

Anion is the negative charged because It receives one electron from the cations thus becomes negatively charged entity. It is attracted towards the positive anode thus it is called anion.

<h2>_____________________________________</h2><h2>Question no 8:</h2><h3>MOLECULES:</h3>

Ionic bond do not form molecules, They form the ions.

<h2>_____________________________________</h2><h2>Question no 9:</h2><h3>Attraction:</h3>

One type of bonding i.e. ionic bonding is formed by the attraction between the positive and negative ions.

<h2>_____________________________________</h2><h2>Question no 10:</h2><h3>LATTICE ENERGY:</h3>

It is the amount of energy required to change the state of matter.

Please Help thank you

I suppose because of the fact that the relative humidity is taking away your heat and making you feel cool, I think that you would feel cooler than someone who was dry.

Using the words cohesive and adhesive, explain why water forms a meniscus?

I am Lyosha [343]

Adhesion is responsible for a meniscus and this has to do in part with water's fairly high surface tension. Water molecules are attracted to the molecules in the wall of the glass beaker. And since water molecules like to stick together, when the molecules touching the glass cling to it, other water molecules cling to the molecules touching the glass, forming the meniscus. They'll travel up the glass as far as water's cohesive forces will allow them, until gravity prevents them from going further. Cohesion is an intermolecular attraction between like molecules (other water molecules in this case).

An unknown metal cylinder has a mass of 34.3 g and a volume of 2.1 mL . What is the density of the metal in g / m * L ?

saul85 [17]

Taking into account the definition of density, the density of the metal is 16.33 $\frac{g}{mL}$ .

<h3>Definition of density</h3>

Density is a quantity that allows us to measure the amount of mass in a certain volume of a substance. Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

$density=\frac{mass}{volume}$

From this expression it can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.

<h3>Density of the metal in this case</h3>

In this case, you know that:

Mass= 34.3 g
Volume= 2.1 mL

Replacing in the definition of density:

$density=\frac{34.3 g}{2.1 mL}$

Solving:

<u><em>density= 16.33 </em></u> $\frac{g}{mL}$

In summary, the density of the metal is 16.33 $\frac{g}{mL}$ .
