The correct answer is A. When free hydrogen ions and free hydroxyl ions are removed from solutions of acids and bases, the acidic and basic properties disappear.
The strength of the acid or base depends upon its degree of ionization. Since different acids and different bases dissociate or ionize to different extent in water so their degree of ionization is also different. Strong acids and strong bases ionize in water completely while the weaker acids or bases ionize partially. Ionization of the weak acids in water are in equilibrium. The degree of ionization is the ratio of the number of ionized molecules to the number of molecules which are dissolved in water. In case of acids the ionized molecules are hydrogen ions and in case of bases hydroxyl ions.
Answer:
D. predicting the age of the plant
Explanation:
stems don't exactly have those powers. but they do give support by holding the plant upright. they do give defensive properties. and they do increase the amount of sun exposure (like with sunflowers). but they don't predict anything.
Answer:
i think b i not 100%
Explanation:
im going to try c on my test
I don't think doctors are supposed to do that but if they are I'm guessing it's probably to kill a infection of some kind or speed up the healing process
Answer:
Our water resources face a host of serious threats, all of which are caused primarily by human activity. They include sedimentation, pollution, climate change, deforestation, landscape changes, and urban growth.
