Why nitration of benzene is easier than that of benzene......... And how is phenol converted to TNT

Explanation:

It is known that like charges repel each other and unlike charges attract each other.

As the balloons are facing each other with like charges so they will repel each other. Hence, they will move apart.

But when balloons were moved further apart then interaction between them will decrease and then there will be no force of repulsion or force of attraction.

The prefix indicates a molecule with 2 carbon atoms is eth- and the correct option is option A.

The IUPAC system of nomenclature is a set of logical rules framed which are mainly aimed at giving an unambiguous name to an organic compound.

IUPAC stands for International Union of Pure and Applied Chemistry

A prefix to the name comes before the molecule. The prefix of the molecule's name is based on the number of carbon atoms.

For example, a chain of six carbon atoms would be named using the prefix hex-.

The suffix to the name is an ending that is applied that describes the types of chemical bonds in the molecule.

Therefore, The prefix indicates a molecule with 2 carbon atoms is eth- and the correct option is option A.

Answer:

A = 66.98 square in.

Explanation:

The Area of a sector is given by the formula

[tex]A = \frac{\theta}{360}\times \pi r^2[/tex]

here θ is the central angle and r is the radius

given that θ = 120° and radius =  8 inches

[tex]A = \frac{120}{360}\times3.14\times 8^2[/tex]

A = 66.98 square in.

Answer:

D. 0.75 grams

Explanation:

The data given on the iridium 182 are;

The half life of the iridium 182, [tex]t_{(1/2)}[/tex] = 15 years

The mass of the sample of iridium, N₀ = 3 grams

The amount left, N(t) after two half lives is given as follows;

[tex]N(t) = N_0 \left (\dfrac{1}{2} \right )^{\dfrac{t}{t_{1/2}} }[/tex]

For two half lives, t = 2 × [tex]t_{(1/2)}[/tex]

∴ t = 2 × 15 = 30

[tex]\dfrac{t}{t_{(1/2)}} = \dfrac{30}{15} = 2[/tex]

[tex]\therefore N(t) = 3 \times\left (\dfrac{1}{2} \right )^2 = 0.75[/tex]

∴ The amount left, N(t) = 0.75 grams

Answer:

The volume of the helium balloon is 0.306 L.

Explanation:

Boyle's law states that the volume occupied by a given gaseous mass at constant temperature is inversely proportional to pressure. That is, if the pressure increases, the volume decreases, while if the pressure decreases, the volume increases.

Mathematically, Boyle's law indicates that the product of pressure and volume always has the same value:

P*V= k

Assuming that you have a certain volume of gas V1 that is at a pressure P1 at the beginning, by varying the volume of gas to a new value V2, then the pressure will change to P2, and it will be fulfilled:

P1*V1= P2*V2

In this case:

Replacing:

2 atm* 0.15 L= 0.97 atm* V2

Solving:

[tex]V2= \frac{2 atm* 0.15 L}{0.97 atm}[/tex]

V2= 0.306 L

The volume of the helium balloon is 0.306 L.

Fluorine has the highest electronegativity in comparison to other elements therefore, the F atom attracts electrons most strongly.

The electronegativity of an atom measures the tendency of an element to attract the bonded electrons pairs towards itself. The electronegativity of an atom is determined with respect to another bonded atom.

Electronegativity can be described as a chemical property of an atom or a functional group to attract electrons toward itself. The electronegativity of an atom depends on the atomic number and the distance of valence electrons from the charged nuclei.

When two different atoms are bonded through a bond. More electronegative will attract the electron density of the bond towards itself.

As we know, the electronegativity decreases as we move down the group in the periodic table. Fluorine is the most electronegative element in the periodic table therefore, Fluorine (F) will attract the electrons toward it most strongly.

Answer:

cu+2 ------ oxidation whereas Cu ------ reduction.

Explanation:

In the reaction, cu+2 is the place where oxidation occurs because this cupric ion losses electrons  which causes +2 charge on it. we know that oxidation is the loss of electrons and reduction is the gaining of electrons so the Cu is the place or atom at which reduction occurs. Electrochemical cells have two electrodes, which is anode and the cathode. The anode is the electrode where oxidation occurs whereas the cathode is the electrode where reduction takes place.

Answer:

20.25 W

Explanation:

Applying,

P = I²R.................... Equation 1

Where P = Power, I = current drawn by the test light, R = Resistance of the test light

From the question,

Given: I = 1.5 A, R = 9.00 Ω

Solution :

Sir Isaac Newton was a great scientist. The discoveries of the Newton change the way we see the world. Newton gave us the fundamental principles through which the entire universe is governed.

Newtons 1st law of motion states that a body moves or stays in position until and unless an external force is applied to the body.

This is the law of nature.

An example which do not support this law can be a body having a huge mass and a small boy applies force to move it but is unable to move the body.
