A solid, a liquid, and a gas are each in separate covered jars. The substances are the same type but different states of matter.

Describe what will happen if the cover of each jar is removed. Explain how the difference in kinetic energy of the substances explains this result.

Explanation:

  • Gases are known to have more kinetic energy than liquids and solids bases on the kinetic molecular theory.
  • Due to the high energy of gases, their molecules are usually far apart and held together by  very weak attractive forces.
  • Liquids are more closely held by stronger attractive forces.
  • Solids are the most closely held by very strong attractive forces.
  • If one opens a jar containing the same matter but at these various states, it is expected that the gases will escape and diffuses to the environment.
  • The solids and liquids will remain in the container.
  • The kinetic energy of gases gives them enough energy to freely be randomized.

2CO(g) + O2(g) = 2CO2(g)
Finger [1]

Answer:

3.0 L O₂

Explanation:

If CO reacts at STP, it means that there are 1.0 moles of CO. To find the moles of O₂, you need to use the mole-to-mole ratio from the given equation.

1.0 moles CO            1 mole O₂
----------------------  x  ---------------------  =  0.5 moles O₂
                                2 moles CO

To calculate the liters of oxygen, you need to use Avogadro's Law:

V₁ / N₁ = V₂ / N₂

In this equation, "V₁" and "N₁" represent the volume and moles of the first molecule. "V₂" and "N₂" represent the volume and moles of the second molecule. You can plug the given and calculated values into the equation and simplify to isolate V₂.

V₁ = 6.0 L                     V₂ = ? L

N₁ = 1.0 moles              N₂ = 0.5 moles

V₁ / N₁ = V₂ / N₂                                            <----- Avogadro's Law

(6.0 L) / (1.0 moles) = V₂ / (0.5 moles)         <----- Insert values

6.0 = V₂ / (0.5 moles)                                   <----- Simplify left side

3.0 = V₂                                                         <----- Multiply both sides by 0.5

Adding O2 to the reaction 6CO2 + 6H2O &lt;---&gt; C6H12O6 + 6O2, WHICH WAY WILL THE REACTION SHIFT?
Alex73 [517]

Increase in Oxygen shift the equilibrium towards reactant side.

<u>Explanation:</u>

6CO₂ + 6H₂O ⇄ C₆H₁₂O₆ + 6O₂

This is the reaction occurs in the photosynthesis of plants by means of sunlight. In this case, if the concentration of Oxygen increases or adding more oxygen to the product side will shift the equilibrium towards the reactant side according to the Le Chatlier's principle, which adjusts the equilibrium by itself for any changes that is increase or decrease in pressure, temperature or concentration of reactants or products.
