Answer:
a. 4v
Explanation:
Alf moves with speed v
Alf travel during the same amount of time that is Δt = (1/4)s
v = (1/4)s / Δt = s / 4 Δt
s / Δt = 4 v
Beth travels a distance s during time Δt,
speed of Beth = s / Δt = 4 v .
Number 4 I think
the atomic mass is 11 because the mass is the sum of protons and neutrons
Answer:
A
Explanation:
because u are subtracting if this is from flvs that is what i did and it was right
Answer:
and 20.86 seconds are the values of the rate constant and the half-life for this process respectively..
Explanation:
Expression for rate law for first order kinetics is given by:
where,
k = rate constant
t = age of sample
= let initial amount of the reactant
a = amount left after decay process
We have :
t = 95 s
Half life is given by for first order kinetics::
and 20.86 seconds are the values of the rate constant and the half-life for this process respectively..
