The kinetic theory state about the relationship between the speed and temperature of gas molecules "As the temperature increases, the speed of gas molecules increases".
<u>Option: </u>C
<u>Explanation:</u>
The temperature relates to a gas, according to the kinetic theory of gases, influences the rate of motion of the gas particles. The higher the gas temperature, the faster the gas particles are moving; the reverse is true, too.
This is because the gas particles gain more kinetic energy as the temperature of the gas increases, and therefore move faster and collide more with each other and the container walls.The rate of a gas's molecules is proportional to the temperature, and is inversely proportional to the gas's molar mass.
The correct answer is <span>D) centrifuge the mixture because the substance with the highter density will be pulled to the bottom
When things spin around, like a centrifuge, the centripetal force draws things towards the middle. If you make it a bit like a spiral and put it sideways, then the denser thing will go to the bottom while the less dense ones will remain on the outside. </span>
Explanation:
As the climate warms, it changes the nature of global rainfall, evaporation, snow, stream flow and other factors that affect water supply and quality.
Answer:
32.1 × 10²³ formula units of CuCl₂
Explanation:
Given data:
Number of moles of CuCl₂ = 5.33 mol
Number of formula units of CuCl₂ = ?
Solution:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
one mole of any substance contain 6.022 × 10²³ formula units thus,
5.33 moles of CuCl₂ = 5.33 ×6.022 × 10²³ formula units
32.1 × 10²³ formula units of CuCl₂
