First divide 451g by kryptons molar mass
451g/84gmol= 5.369047619moles
Then multiply 5.369047619moles by 22.4L(volume 1 mol of a gas occupies at STP)
5.369047619moles x 22.4L= 120.26L
Answer: 120.26L
Hoped this helped to explain molar conversions it can be hard to understand at first but you will get the hang of it
Answer:
The answer is Ce^4+ (aq) + Mn^2+ (aq) ==> Ce^3+ (aq) + Mn^3+ (aq)
Explanation:
The reaction is first order with respect to Ce^4+ and first order with respect to Mn^2+ below.
Ce^4+ (aq) + Mn^2+ (aq) ==> Ce^3+ (aq) + Mn^3+ (aq)
The rate calculation,
Ce^4+ (aq) + Mn^2+ (aq) ==> Ce^3+ (aq) + Mn^3+ (aq)
This is the catalyzed reaction.
Answer: Option (b) is the correct answer.
Explanation:
Buffere is defined as the solution to whom when an acid or base is added then it resists any in change in pH of the solution.
This is because a buffer has the ability to not get affected by the addition of small amounts of an acid or a base. So, basically it keeps the concentration of both hydrogen ions and hydroxides equal. As a result, it helps in maintaining the pH of the solution.
And, the capacity of a buffer solution to resist the change is known as buffer capacity.
Thus, we can conclude that buffering capacity refers to the extent to which a buffer solution can counteract the effect of added acid or base.
Answer:
P1V1 = P2V2
(1.5 atm)(5.6 L) = (x)(4.8 L) x = 1.8 atm
