Consider a 1.0-L sample of helium gas and a 1.0-L sample of argon gas, both at room temperature and atmospheric pressure. Do the atoms in the helium sample have the same average kinetic energy as the atoms in the argon sample

Answers

Yes, the atoms in the helium sample have the same average kinetic energy as the atoms in the argon sample.

What is Average Kinetic Energy ?

The average kinetic energy of a gas molecule is defined as the product of half of the mass of each gas molecule and the square of the RMS speed.

The average kinetic energy equation is independent of Molar mass.

It's only a function of temperature.

So if they're at the same temperature they will have the same average kinetic energy.

Therefore, the atoms in the helium sample have the same average kinetic energy as the atoms in the argon sample

Answers

The wavelength of an electromagnetic wave that has a frequency of 1.82 x 10¹⁸ Hz in a vacuum is 1.65 × [tex]10^{-10}[/tex]m.

How to calculate wavelength?

The wavelength of a wave can be calculated by dividing the speed of the wave by its frequency.

According to this question, a wave has a frequency of 1.82 x 10¹⁸ Hz in a vacuum and speed of light in a vacuum is 3.00 × 10⁸ m/s.

λ = [tex]\frac{v}{f}[/tex]

Wavelength (λ) = 3 × 10⁸ ÷ 1.82 × 10¹⁸

Wavelength (λ) = 1.65 × [tex]10^{-10}[/tex] m

Therefore, the wavelength of an electromagnetic wave that has a frequency of 1.82 x 10¹⁸ Hz in a vacuum is 1.65 × [tex]10^{-10}[/tex]m.

A. -0.183°C
B. 0.0606 °C
C. 0.217°C
D. -0.634°C

Answers

From the calculations, we can see that, the change in the freezing point is -0.634°C.

What is freezing point?

The term freezing point refers to the temperature at which a liquid is changed to solid.

Given that;

ΔT = K  m i

Number of moles sucrose = 35.0 g/ 342.30 g/mol = 0.1 moles

molality =  0.1 moles/ 300.0 * 10^-3 Kg

The amount of energy transferred to the coin is ???
joules.

Answers

28.5 J is the amount of energy transferred to the coin.

What is specific heat capacity?

The specific heat capacity is defined as the quantity of heat (J) absorbed per unit mass (kg) of the material when its temperature increases by 1 K (or 1 °C), and its units are J/(kg K) or J/(kg °C).

Energy is calculated mCΔT formula  where,

m(mass)= 6.30  grams

C(specific heat capacity)= 0.377 j/g

ΔT(change in temperature)= 32.0°C- 20°C= 12 °C

Energy is, therefore:

Q = mCΔT

Q= 6.30 g  x 0.377  j/g /°C x   12 °C

Q= 28.5 J

Use the following equation to answer the following question
3 H2 + Na2 —-> 2 NH3

a) Determine the limiting reactant when 5.78 g of H2, and 6.28 g N2 are reacted to make NH3 you expect to get out of the chemical reaction.

Answers

Answer: nitrogen

Explanation:

Converting 5.78 g of hydrogen to moles, we know that the formula mass of hydrogen is about 2(1.00794)=2.01588 g/mol, so 5.78 grams is about 5.78/2.01588=2.867 mol.Converting 6.28 g of nitrogen to moles, we know that the formula mass of nitrogen is about 2(14.0067)=28.0134 g/mol, so 6.28 grams is about 6.28/28.0134 = 0.22417 mol.

From the equation, we know that for every 3 moles of hydrogen consumed, 1 mole of nitrogen is consumed.

Considering the hydrogen, the reaction can occur 2.867/3=0.955 times.Considering the nitrogen, the reaction can occur 0.22417 times.

Therefore, nitrogen is the limiting reactant.
