Answer:
Here's what I think
Explanation:
They wanted you to understand that, to a geologist, the stripes on the rock are like the pages of an encyclopedia of information.
You start reading and getting information from page 1 of an encyclopedia, then go on to the next page, and so on.
In the same way, the lowest layer of stripes is the oldest and gives information on the earliest geological period. The layer above it gives you information on the next period, and so on.
Answer:
⇒D_AB= 1.21×10^(-9)
Explanation:
Wike chang equation is given as:

Where
D_AB= diffusivity of chlorine in water
Φ= 2.26 for water as solvent
ν= 0.0484 for chlorine as solute
M_B = Molecular weight of water
τ= temperature=289 K
μ= viscosity = 1.1×10^{-3}
Now putting these values in the above equation we get

⇒D_AB= 1.21×10^(-9)
Either covalent compounds are neutral, covalent compounds share electrons
