Explanation:

Kinetic energy is defined as the energy obtained by an object due to its motion.

This means that any object which is moving will have kinetic energy because it is in motion.

Mathematically, K.E = $\frac{1}{2}mv^{2}$

where, m = mass of object

v = volume of object

Whereas if an object is not moving and if it is only lying in a certain position then it will have only potential energy.

Thus, we can conclude kinetic energy is the energy obtained by an object due to its motion.

. The shell around the nucleus can be numbered from near to the nucleus as 1, 2, 3, 4,

taurus [48]

Answer:

He numbered these orbits due to their location.

Explanation:

Scientist Neil Bohr in his atomic model describes that electrons are moving with high velocity in circular paths around the nucleus is called shells or orbits. As long as electrons are in their particular orbit their energy is constant. He named those orbits as K- shell, L- shell and M- shell etc. When the electron absorb energy, it is able to jump to the next shell and comes back to its original shell when it loses energy. He also give numbers i.e. 1,2,3,4 to the shells due to their nearness to the nucleus. Shell 1 is near to the nucleus whereas shell 4 is farther from the nucleus.

It was found that 2.35 g of a compound of phosphorus and chlorine contained 0.539 g of phosphorus. What are the percentages by m

igor_vitrenko [27]

Answer:

Explanation:

P = 2.35g

Cl= 0.539 g

% MASS = mass of X/ mass of a compound

% mass of P = 2.35 / (2.35+ 0.539) = 81.34%

% mass of Cl = 0.539 /(2.35+ 0.539) = 18.66 %

Which of the following is not a conjugate acid-base pair? A) NH4+/NH3 B) H30-OH OC) H2SO3/HSO3 D) C2H302-/HC2H302

raketka [301]

Answer : The option (d) is not a conjugate acid-base pair.

Explanation :

According to the Bronsted Lowry concept, Bronsted Lowry-acid is a substance that donates one or more hydrogen ion in a reaction and Bronsted Lowry-base is a substance that accepts one or more hydrogen ion in a reaction.

Or we can say that, conjugate acid is proton donor and conjugate base is proton acceptor.

(a) The equilibrium reaction will be,

$NH_4^++OH^-\rightleftharpoons NH_3+H_2O$

In this reaction, $NH_4^+/NH_3$ are act as a conjugate acid-base.

(b) The equilibrium reaction will be,

$H_3O^++OH^-\rightleftharpoons H_2O+H_2O$

In this reaction, $H_3O^+/OH^-$ are act as a conjugate acid-base.

(c) The equilibrium reaction will be,

$H_2SO_3+OH^-\rightleftharpoons HSO_3^-+H_2O$

In this reaction, $H_2SO_3/HSO_3^-$ are act as a conjugate acid-base.

(d) The equilibrium reaction will be,

$C_2H_3O_2^-+H_2O\rightleftharpoons HC_2H_3O_2+OH^-$

In this reaction, $C_2H_3O_2^-/HC_2H_3O_2$ are act as a conjugate base-acid.

Hence, from this we conclude that, the option (d) is not a conjugate acid-base pair but it is a act as conjugate base-acid.

Nitrobenzene contains 5 hydrogen atoms 6 carbon atoms 2 oxygen atoms and 1 nitrogen atom. what is the chemical formula for nitro

tamaranim1 [39]

To develop the chemical formula of a substance or compound in this regard, one only needs to write the chemical symbol for each of the element present and write as subscript to each symbol the number of atoms of that element. For nitrobenzene, as described above, the chemical formula should be,
C₆H₅O₂N
