Answer: You need a control group because......
Explanation: You need a control group in order to study if there is any difference in behavior between two groups when an external stimulant is introduced.
Dry and desert conditions
4.37*v=2.33*0.755
V=1.76/4.37
V=0.4025 l
We say that the solution is unsaturated.
Explanation:
If the salt solubility is 36 g in 0.1 L of water then we can dissolve 360 g of salt in 1 L of water.
Because the solution contains 200 g of salt in 1 L of water, the solution is unsaturated because more salt can be added until we reach the saturation point.
We call the solution dilute when we compare the concentration of a solution with the concentration of another solution, but here we do not compare different solutions.
