Answer:
the correct answer is 36
Explanation:
The two substances are sodium chloride and lead nitrate
In case of sodium chloride;
mass of water = 100 kg
solubility of sodium chloride = 54 g / 100 g of water
Therefore the mass of sodium chloride required for full saturation,
L = (54/100) x 100 kg = 54 kg
In case of lead nitrate;
mass of water = 200 kg
mass of lead nitrate = 36 kg
if the solution is fully saturated, solubility of lead nitrate (g per 100 g of water)
k = (36/200) x 100 g = 18 g
k can be also written as 18 kg per 100 kg of water.
thus the difference in k and l = (54-18) = 36.
Ok. Lets pretend you see a habitat in the wood. You see the food chain of all the animals. mouse, fox, bear, human. Lets say a zoo decides to get rid of their foxes and dumps them in this forest. Then, instead of 20, you have 30 foxes. All of the mice are gone in a matter of weeks. So the Foxes start to slowly drop out. Then, theres not much for the bears to eat, so the bears start dying. Then, the humans can't hunt bears. It sets the whole chain of the forest off. Next, the humans will switch to dears, and all the dears will be killed off... etc... etc... Make sense? Got a question?
