Which statement best describes the collisions of gas particles according to the kinetic-molecular theory?

1 answer:

B. As particles travel in straight lines, their paths sometimes meet, and then they bounce apart with no gain or loss of energy.

Explanation:

The best statement that describes the collision of gas particles according to the kinetic-molecular theory is that as particles travel in straight lines, their paths sometimes meet and then they bounce apart with no gain or loss of energy.

The kinetic molecular theory is used to explain the forces between molecules and their energy.

One of the postulate suggests that, when molecules collide with each other, or with the wall of the container, there is no loss or gain of energy.

Molecules are independent of one another and that forces of attraction and repulsion between molecules are negligible.

At what temperature would 2.10moles of N2 gas have a pressure of 1.25atm and fill a 25.0 L tank

hodyreva [135]

Answer:

$\large \boxed{\text{-92 $^{\circ}$C}}$

Explanation:

We can use the Ideal Gas Law and solve for T.

pV = nRT

Data

p = 1.25 atm

V = 25.0 L

n = 2.10 mol

R = 0.082 06 L·atm·K⁻¹mol⁻¹

Calculations

1. Temperature in kelvins

$\begin{array} {rcl}pV & = & nRT\\\text{1.25 atm} \times \text{25.0 L} & = & \rm\text{2.10 mol} \times 0.08206 \text{ L}\cdot\text{atm}\cdot\text{K}^{-1}\text{mol}^{-1} \times T\\31.25&=&0.09847T\text{ K}^{-1}\\T& = &\dfrac{31.25}{\text{0.098 47 K}^{-1}}\\\\& = &\text{181 K}\end{array}$

2. Temperature in degrees Celsius

$\begin{array} {rcl}T & = & (181 - 273.15) \, ^{\circ}\text{C}\\& = & -92 \, ^{\circ}\text{C}\\\end{array}\\\text{The temperature of the gas is $\large \boxed{\mathbf{-92 \, ^{\circ}}\textbf{C}}$}$

Two different compounds are obtained by combining nitrogen with oxygen. the first compound results from combining 46.7 g of n wi

kondaur [170]

<span>First:

46.7 g of N with 53.3 g of O,

=> mass ratio O to N = 53.3 / 46.7 = 1.1413

Second

17.9 g of N and 82.0 g of O.

mass ratio of O to N = 82.0 / 17.9 = 4.5810

Third

Ratio of the mass ratio of O to N in the second compound to the mass ratio of O to N in the first compound =

= 4.5810 / 1.1413 = 4.013 ≈ 4

What mass of copper is consumed in the reaction with hydrochloric acid if 10.0 g of gas is collected?

brilliants [131]

Answer:

317 g

Explanation:

Cu + 2HCl --> CuCl2 +H2

1 : 2 1 : 1

1 mole of Cu = 63.5 g

1 mole of H2 = 2g

1 mole Cu produces = 1 mole of H2

63.5 g of Cu produces = 2 g of H2

10 g of H2 will be produced from = (63.5/2)*10 = 317 g of Copper
