Determine the change in energy when an electron transitions from n= to n=5?

Answers

Answer:

ΔE = 13.056 ev

Explanation:

Energy associated with nth state is,

En = -13.6/n²

For n = 1

E₁ = -13.6 / 1²

E₁ = -13.6/1

E₁ = -13.6 ev

Kinetic energy of electron = -E₁ = 13.6 ev

For n = 5

E₅ = -13.6 / 5²

E₅ = -13.6/25

E₅ = -0.544 ev

Kinetic energy of electron = -E₅ = 0.544 ev

Wavelength of radiation emitted:

ΔE = hc/λ = E₅ - E₁

by putting values,

ΔE = -0.544ev - (-13.6 ev )

ΔE = 13.056 ev

How many moles of H3PO4 are contained in 150.0 mL of 18.1 M H3PO4?

Answers

Answer:

Number of moles = 2.72 mol

Explanation:

Given data:

Number of moles of H₃PO₄ present = ?

Molarity of solution = 18.1 M

Volume of solution = 150.0 mL (150/1000 = 0.15 L)

Solution:

Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.

Formula:

Molarity = number of moles of solute / L of solution

By putting values,

18.1 M = number of moles / 0.15 L

Number of miles = 18.1 M × 0.15 L

Number of moles = 2.72 mol

Why is a map considered a model?

Answers

Answer:

Every map is a representation of reality, thus a model in the broadest sense. Sometimes mapping is distinguished from modelling by stating that mapping is a simple representation of reality, while modelling is trying to cover more complexity in reality.

Explanation:

Titanium metal is used as a structural material in many high-tech applications such as jet engines. What is the specific heat of titanium in J/g°C if it takes 99.7 J to raise the temperature of a 34.7 g block by 5.20°C?

Answers

Answer:

0.553 J/g°C

Explanation:

From the question given above, the following data were obtained:

Heat (Q) required = 99.7 J

Mass (M) = 34.7 g

Temperature change (ΔT) = 5.20 °C

Specific heat capacity (C) =?

Thus, we can obtain the specific heat capacity of titanium as follow:

Q = MCΔT

99.7 = 34.7 × C × 5.20

99.7 = 180.44 × C

Divide both side by 180.44

C = 99.7 / 180.44

C = 0.553 J/g°C

Therefore, the specific heat capacity of titanium is 0.553 J/g°C.
