Answer: Option (b) is the correct answer.
Explanation:
When it rains, then mud in the backyards become wet. It is known that earthworms live inside earth and diffusion of oxygen gets slower through water than through air.
As a result, supply of oxygen to the worms decreases in wet mud hence, they come to the surface in order to breathe.
Thus, we can conclude that wet mud in the backyard most likely formed the earthworms.

Answer:
4.1g of Cr will make (317/104) x 4.1 = 12.5g of CrCl3
C. Metals higher in the series will replace metal ions in solution that
are lower in the series.
Explanation:
The activity series of metals shows the extent of reactivity of different metals.
On the activity series, the most reactive metals are located higher up on the able whereas the less reactive ones are found at the bottom of the series.
- We can tell if single displacement reactions will occur by simply looking at the reactivity series.
- Metals that are more reactive will displace the ones that are not very reactive that are positioned down the series. Such a reaction will occur.
- Metals lower in the series cannot displace the ones on top because they are less reactive. Such a reaction will not occur.
