Crushing a can, breaking glass, cutting paper, boiling water, chopping wood, and mixing water and sand
Answer: It will take 8.2 minutes until the concentration decreases to 0.055 M
Explanation:
The time after which 99.9% reactions gets completed is 40 minutes
Explanation:
Expression for rate law for first order kinetics is given by:
where,
k = rate constant
t = age of sample
a = let initial amount of the reactant
a - x = amount left after decay process
a) for completion of half life:
Half life is the amount of time taken by a radioactive material to decay to half of its original value.
b) Time taken for 0.085 M to decrease to 0.055 M
Thus it will take 8.2 minutes until the concentration decreases to 0.055 M
Please add you assignment.
Vf = Vi + t
Vf = 20 m/s + 2 m/s x 30 s
Vf = 80 m/s
I think it’s S umm let me know if I’m wrong but I’m. 80 precent sure it’s S
