Explanation:

Electronegativity is defined as the ability of an atom to attract electrons towards itself.

Whereas when there is difference in values electronegativity of two different atoms then it is known as electronegativity difference.

For example, in a HCl compound the hydrogen atom is electropositive and chlorine atom is electronegative. Electronegativity value of hydrogen is 2.1 and chlorine has 3.0.

Hence, difference in their electronegativities is 3.0 - 2.1 = 0.9.

Also, it is known that when the electronegativity difference is less than or equal to 1.7 then the bond formed between the combining atoms will be polar covalent.

(80+125+45) / 10 = 250/10 =25
25 meters per minute= 0.41 meters/second

the direction and stopping time is irrelevant to the problem.

Given the reaction: A + B <--> C + D

Lady_Fox [76]

Answer:

A.) 4.0

Explanation:

The general equilibrium expression looks like this:

$K = \frac{[C]^{c} [D]^{d} }{[A]^{a} [B]^{b} }$

In this expression,

-----> K = equilibrium constant

-----> uppercase letters = molarity

-----> lowercase letters = balanced equation coefficients

In this case, the molarity's do not need to be raised to any numbers because the coefficients in the balanced equation are all 1. You can find the constant by plugging the given molarities into the equation and simplifying.

$K = \frac{[C]^{c} [D]^{d} }{[A]^{a} [B]^{b} }$ <----- Equilibrium expression

$K = \frac{[2 M] [2 M]}{[1 M] [1 M] }$ <----- Insert molarities

$K = \frac{4}{1 }$ <----- Multiply

$K = 4$ <----- Divide
