A typical cell phone uses wavelength of 0.36meters. How much energy does this wave have?

Answers

Answer:

55×10^-26 J

Explanation:

We can calculate the energy of the wave from

E= hc/λ

Where

h= Planks constant = 6.6×10^-34 Is

c= speed of light = 3×10^8 ms-1

λ= wavelength of the wave = 0.36 metres

Recall that cell phone use radio waves which belong to the electromagnetic spectrum hence it must possess the speed of light.

E= 6.6×10^-34 × 3×10^8/ 0.36

E= 55×10^-26 J

Hence the energy possessed by 0.36 meters wavelength radio waves is 55×10^-26 J

B. If the sand you ran across has a specific-heat capacity of 835 J/(kgºc),
how much energy must be added to a 2-kilogram pile of it to increase its
temperature from 40°C to 50°C? Show your work. (3 points)

Answers

Answer: 16700 Joules

Explanation:

The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.

[tex]Q=m\times c\times \Delta T[/tex]

Q = Heat absorbed = ?

m = mass of sand = 2 kg

c = heat capacity = [tex]835J/kg^0C[/tex]

Initial temperature  = [tex]T_i[/tex] = [tex]40^0C[/tex]

Final temperature= [tex]T_f[/tex]  = [tex]50^0C[/tex]

Change in temperature ,[tex]\Delta T=T_f-T_i=(50-40)^0C=10^0C[/tex]

Putting in the values, we get:

[tex]Q=2kg\times 835J/kg^0C\times 10^0C[/tex]

[tex]Q=16700J[/tex]

16700 J of energy must be added to a 2-kilogram pile of it to increase its temperature from 40°C to 50°C

Answers

Answer: The reaction of one mole of oxygen [tex](O_2)[/tex] releases 445 kJ of energy.

Explanation:

Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and [tex]\Delta H[/tex] for the reaction comes out to be negative.

Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and [tex]\Delta H[/tex] for the reaction comes out to be positive.

[tex]CH_4(g)+2O_2(g)\rightarrow CO_2(g)+2H_2O(l)[/tex]  [tex]\Delta H=-890kJ[/tex]

on halving the reaction, enthalpy also becomes half

[tex]\frac{1}{2}CH_4(g)+O_2(g)\rightarrow \frac{1}{2}CO_2(g)+H_2O(l)[/tex]  [tex]\Delta H=-445kJ[/tex]

Thus The reaction of one mole of oxygen [tex](O_2)[/tex] releases 445 kJ of energy.

How many joules are produced when 45 gram of copper is placed into water that releases them temperature from 12c to 71c (c)=0.75j/g*c

Answers

Answer:

Heat energy (Q) = 1.9925 KJ = 2 KJ (Approx)

Explanation:

Given:

Mass of copper (M) = 45 gram

Change in temperature (ΔT) = 71°C - 12°C = 59°C

Specific heat (c) =0.75 j /g*c

Find:

Heat energy (Q) = ?

Computation:

Heat energy (Q) = Mass(M) × Change in temperature (ΔT) × Specific heat (c)

Heat energy (Q) = 45 gram × 59°C × 0.75 j /g*c

Heat energy (Q) = 1991.25 J

Heat energy (Q) = 1.9925 KJ = 2 KJ (Approx)

At 25ºC, the average velocity of a hydrogen molecule is 1.92 x 103 m/s. What is the average velocity of a nitrogen molecule at the same temperature?
NEED WORK

Answers

Answer:

V = 513.36m/s

Explanation:

Temperature (T) = 25°C = (25 + 273.15) = 298.15K

Speed (V) = 1.92*10³m/s

According to kinetic theory of gases, the speed (v) of a molecule is

V= √(3RT / M)

V = speed or velocity

R = ideal gas constant = 0.082J/mol.K

T = temperature of the gas

M = molar mass

Molar mass of hydrogen molecule = 2.0g/mol

Molar mass of Nitrogen molecule = (2×14.0) = 28.0g/mol

Since they're in the same temperature

V1 / V2 = √(M2 / M1)

1.92×10³ / V2 = √(28 / 2)

1.92×10³ / V2 = √(14)

1.92*10³ / V2 = 3.74

1.92*10³ = 3.74V2

V2 = 1920 / 3.74

V2 = 513.36m/s

The velocity of Nitrogen molecule is 513.36m/s

the mass of orange candies divided by total mass of candies
the volume of brown candies divided by volume of orange candies
the actual number of orange candies
the number of orange candies divided by number of brown candies
the number of orange candies plus number of brown candies

Answers

Answer:

the number of orange candies divided by total number of candies

the mass of orange candies divided by total mass of candies

Explanation:

The two correct options that are appropriate to describe the concentration of orange candies would be the number of orange candies divided by total number of candies and the mass of orange candies divided by total mass of candies.

The concentration of a substance can be described as the fraction of that substance in a particular mix of substances.

In term of number, the concentration of a substance in a mix of substances can be expressed as the number of that substance divided by the total number of substances in the mix.

In term of mass, the concentration of a substance in a mix of substances can be expressed as the mass of that substance divided by the total mass of the mix.

how many moles of solute are present in 50.0 ml of 0.20 m kno3

Answers

Answer: Volume =  50.0 mL in liters : 50.0 / 1000 = 0.05 L

n = M x V

n = 0.20 x 0.05

n = 0.01 moles of solute

Explanation:

The number of moles of solute are present in 50.0 mL of 0.20 M of KNO₃ solution is 0.01 moles.

How do we calculate moles?

Moles will be calculated by using the molarity formula because molarity is define as the no. of moles of solute present in per liter of the solution as:

M = n/V, where

M = molarity of KNO₃ = 0.2 M

V = volume of solution = 50mL = 0.05L

Moles will be calculated as:

n = (0.2)(0.05) = 0.01 moles

Hence required moles are 0.01 moles.
