Chemicals are brought in through photosynthesis
Answer:
(a). 2
(b). 1/3
(c). 11.11
Explanation:
(a). k= (t₍s₎-t₍o₎)/t₍o₎...............(1)
where k= retention factor,
t₍o₎=solvent time, t₍s₎= solute time.
Given t₍s₎=9.0 Minutes, t₍o₎=3.0 minutes.
∴ k= (9-3)/3
k= 2.
(b). the fraction of time the solute spend in the mobile phase in the column is the ratio of the solvent time to the solute time. = t₍o₎/t₍s₎..........(2)
= 3/9
=1/3.
(c). K=k(Vm/Vs)................(3)
where K= partition coefficient, k= retention factor, Vm=volume of mobile phase, Vs= volume of stationary phase.
∴K = k(Vm/Vs)
k=2, and Vs=0.18Vm.
∴K = 2(Vm/0.18vm)
⇒K = 2/0.18
∴K=11.11
You drove 20 more mph than what you did before. The more force is 20 because you drove 20 more mph.
What fossil images, there are no pictures attached.
Answer:
c. density decreases because the molecules move farther apart
Explanation:
As a liquid is heated, the molecules move faster and move farther apart. This causes the volume to increase, which causes the density to decrease.
