What is the correct equilibrium constant expression for the following reaction? 3A2 = 2B3 when the reaction started with the initial concentrations of A2 = 3 M and B3 = 2 M and continued until the equilibrium concentrations of A2 = 2.5 M and B3 = 2.5 M

Answers

Answer 1
Answer:

Answer:

Kc = [B₃]²/[A₂]³  = 0.40

Explanation:

3A₂ ⇄ 2B₃  

Given at equilibrium =>  [A₂] =2.5 and [B₃] = 2.5

Kc = [B₃]²/[A₂]³ = (2.5)²/(2.5)³ = (2.5)⁻¹ = 0.40

What is the distance between (–6, 2) and (8, 10) on a coordinate grid? mc017-1.jpg mc017-2.jpg mc017-3.jpg mc017-4.jpg

Answers

Ans: Distance = 16.1

Let us consider point A with coordinates (x1,y1) and point B with coordinates (x2,y2)

The distance between the two points is given as:

d(A,B) = √(x2-x1)² +  (y2-y1)²

Here: (x1,y1) = (-6,2)

(x2,y2) = (8,10)

d = √(8-(-6))² + (10-2)²

   = √196+64 = √260 = 16.1

The distance between  (–6, 2) and (8, 10) is 2√65

Distance Formula

The distance formula is used to calculate the distance between two points(x₁, y₁)(x₂, y₂).

Therefore,

  • d = √(x₂ - x₁)²+(y₂ - y₁)²

x₁ = -6

x₂ = 8

y₁ = 2

y₂ = 10

Therefore,

d = √(8+6)²+(10-2)²

d = √(14)² + (8)²

d = √196 + 64

d = √260

d = √4 × 65

d = 2√65

If there is direct variation and y=75 when x=25, find x when y=48.A. x=16

B. x=10

C. x=12

D. x=14

Answers

If there is direct variation and y=75 when x=25,when y=48 X = 16. Therefore, option A is correct.

What is direct variation ?

link between two variables that can be described mathematically by an equation where one variable equals a constant multiplied by the other. For instance, the constant of variation is k = = 3 if y varies straight as x and y = 6 when x = 2. Consequently, y = 3x is the equation that describes this directvariation.

When x is not equal to zero, an equation of the form y = kx describes the linear function known as direct variation. When x is not equal to zero and k is a nonzero real number constant, the equation of the form xy = k describes the nonlinear function known as inverse variation.

x = ky

where k is constant

25 = k × 75

25 / 75 = k

k = 1 / 3

now when y = 48 then substitute the values

x = ky

x = 1 ÷ 3 × 48

x = 16

Thus, option A is correct.

x = ky where k is a constant

first u find k so :
25 = k * 75
25/75 = k
k = 1/3

now when y = 48 just substitute the values
x = ky
x = 1/3 * 48
x = 16

the answer is A) x=16

a chemist encounters an unknown metal. They drop the metal into a graduated cylinder containing water, and find the volume change is 3.2 mL. If the metal weighs 1.5g, what is the density in g/mL of the metal?

Answers

The density of metal will be "0.469 g/mL".

The given values in the question are:

  • Mass of metal = 1.5 g
  • Volume of metal or Volume change = 3.2 mL

Now,

The density of metal will be:

Density = (Mass)/(Volume)

By substituting the given values, we get

→               = (1.5)/(3.2)

→               =0.469 \ g/mL

Thus the above is the appropriate answer.

The density of the metal is 0.47 g/mL

The density of an object is defined as the mass of the object per unit volume of the object.

Density = mass / volume

With the above formula, we can obtain the density of the metal. This is illustrated below:

Volume of metal = change in volume of water = 3.2 mL

Mass of metal = 1.5 g

Density of metal =?

Density = mass / volume

Density = 1.5 / 3.2

Density of metal = 0.47 g/mL

Therefore, the density of the metal is 0.47 g/mL
