Answer:
The amount of NaF produced is doubled.
(d) is correct option.
Explanation:
Given that,
A 2 mole sample of F₂ reacts with excess NaOH according to the equation.
The balance equation is
If the reaction is repeated with excess NaOH but with 1 mole of F₂
The balance equation is
Hence, The amount of NaF produced is doubled.
(d) is correct option.
Answer:
I) increasing the reaction temperature shift equilibrium left
II) decreasing the reaction temperature equilibrium right
Explanation:
The equation C6H12O6(s)+6O2(g)⇌6CO2(g)+6H2O(g) represent cellular respiration where glucose is oxidized by oxygen to yeild carbon dioxide and water respectively. Also energy is released to drive cellular processes.
Since, cellular respiration is an exothermic reaction:
- increasing the reaction temperature shift equilibrium to left favoring the reactants, glucose and oxygen production
- decreasing the reaction temperature shift equilibrium to right favoring the products, carbon dioxide and water production
1. I think you chose the right answer, the equation has the states of the reactants and products.
2. I think you chose the right answer.
3. I think you also chose the right answer. Assuming that the Hrxn is written as kJ per mol CH4
4. Heat of solution is the enthalpy change associated with dissolving a solute in a solvent. I think the first choice is the right one.
5. I think you chose the right answer.
Answer:
Explanation:
Hello,
In this case, considering that the formed liquid is solution is ideal, we can relate the vapor pressure and molar fraction of water with the total vapor pressure of the solution by using the Dalton's equilibrium-based law:
In such a way, we compute the molar fraction of water by computing its moles as well as diglyme:
Thus, the mole fraction of water:
Thereby, the vapor pressure of the solution:
Regards.
Answer:
Because there is no friction, Newton's first law states that the ball should continue to roll. (continue at a constant speed)
Explanation:
Unless acted upon by an unbalanced force, Newton's first law of motion states that an object at rest stays at rest and an object in motion stays in motion with the same speed and direction.
