Answer:
T₁ = 563.19 K
Explanation:
Given data:
Initial volume = 359 mL
Final volume = 269 mL
Final temperature = 422 K
Initial temperature = ?
Solution:
The given problem will be solve through the Charles Law.
Charles Law:
According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
T₁ = V₁T₂ / V₂
T₁ = 359 mL × 422 K / 269 mL
T₁ = 151498 mL.K / 269 mL
T₁ = 563.19 K
B. That the reaction is reversible
The ↔ sign is used in reactions where the equilibrium constant of the forward reaction is close to the equilibrium constant of the backward reaction. This results in the backward reaction being possible. An example of such a reaction is:
N₂ + 3H₂ ↔ 2NH₃
Answer:
Its B Nylon
Explanation:
i just took the quiz and got it right.
Write the unbalanced chemical equation next you’ll have to determine how many atoms of each element are present on each side. Add coefficients to balance mass. Last is to add coefficients to oxygen and hydrogen atoms The reason is that they usually appear in multiple reactants and products, so if you tackle them first you’re usually making extra work for yourself. Now, look at the equation to see which coefficient will work to balance oxygen.
