Answer: The reaction will shift in left or backward direction.
Explanation:
Any change in the equilibrium is studied on the basis of Le-Chatelier's principle. This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.
For the given equation:
As the given reaction is exothermic as the heat is released in the reaction. When the temperature is raised , the reaction will shift in a direction where temperature is decreasing and that is the reverse reaction which is endothermic in nature.
Thus the reaction will shift in left or backward direction.
Answer:
20.4g
Explanation:
First, we need to write a balanced equation for the reaction of butane to produce carbon dioxide.
When butane undergo Combustion, it will produce carbon dioxide and water as shown below:
2C4H10 + 13O2 —> 8CO2 + 10H2O
Molar Mass of C4H10 = (12x4) + (10x1) = 48 + 10 = 58g/mol
Mass of C4H10 from the balanced equation = 2 x 58 = 116g
Molar Mass of CO2 = 12 + (2x16) = 12 + 32 = 44g/mol
Mass of CO2 from the balanced equation = 8 x 44 = 352g
From the equation,
116g of C4H10 produced 352g of CO2.
Therefore, Xg of C4H10 will produce 61.9g of CO2 i.e
Xg of C4H10 = (61.9 x 116)/352 = 20.4g
Therefore, 20.4g of butane(C4H10) is needed to produce 61.9g of CO2
Answer:
Chlorine takes electrons from potassium in the reaction.
Explanation:
2K + Cl₂ ⟶ 2KCl
The KCl is an ionic solid.
It consists of K⁺ and Cl⁻ ions that are formed by the transfer of an electron from K to Cl.
The chlorine takes electrons from potassium, and Gain of Electrons is Reduction.
At the same time, potassium loses electrons to chlorine, and Loss of Electrons is Oxidation.
Both oxidation and reduction are occurring, so this is an oxidation-reduction reaction.
Condensation would occur at that time
Answer:
The liquid boils.
Explanation:
Vapor pressure is simply defined as the pressure exerted on a substance (solid/liquid) by the vapor of the substance collected just at the top of the surface of the substance. In concise words, it is the pressure of Vapor that is in contact with its solid or liquid state.
For a liquid, it is the pressure of the Vapor gathering at the top of the surface of the liquid.
When this Vapor pressure matches the external pressure, the temperature stays constant and the molecules of the liquid all through the liquid can gain enough energy, rise to the surface of the liquid and break free in gaseous form; thereby, boiling.
The definition of boiling point basically explains that it is the point at which temperature stays constant, and the vapour pressure of the liquid matches the atmospheric/external pressure around the liquid and its liquid molecules change into vapor.
This is why liquids boil faster at higher altitudes; the atmospheric pressure at higher altitudes is reduced, hence, the temperature at which liquid boils at this high altitude is normally lower than its known boiling point temperature.
It is also why food cooks to a temperature higher than the boiling point of water in a pressure cooker/pot. The added pressure ensures that the cooking water boils at temperatures higher than its boiling point; thereby exposing the cooking ingredients to a higher temperature, leading to faster cooking.
Hence, it is obvious why boiling is the answer to this question.
