Answer:
2H₂O (l) ⇄ H₃O⁺ (aq) + OH⁻(aq)
Explanation:
The autoionization of water is defined as a chemical reaction where there is an equilibrium in which two water molecules react producing an hydronium ion and a hydroxide ion. This is also defined as the autoprotolysis of water, and is based on its amphoteric nature.
The substance that can donate protons as well as receive them is defined as amphoteric. In this way, the water behaves amphoteric as it donates a proton as an acid of Brownsted Lowry or if it receives a proton, being a base.
NH₃ + H₂O ⇄ NH₄ + OH⁻ Kb
In this case, water behaves as an acid, it donates the proton to ammonia (a base)
CH₃COOH + H₂O ⇄ CH₃COO⁻ + H₃O⁺ Ka
For this case, water behaves as a base, it recieves the proton from the acetic acid (acid)
Molecules that make up for the body are continuously broken down or used up. They must be replaced, some nutrients, proteins, provide building materials for that purpose. Other nutrients including proteins vitamins and minerals are needed to regulate body processes
Not sure but i think living things adapt to their environment.
Adaptations are traits giving an organism an advantage in a certain environment. And variations of individuals is important for a healthy species. So i think adaptation might be the right answer because animal will try to adapt the certain environment. I hope this answer will help you.
Answer:
B.
Explanation:
Oxidation - losing electrons. It is Zn, and it is losing 2 electrons.
Answer:
Displacement. (I think)
Explanation:
When you observe both a bowling ball and a feather falling to the ground at the same time, you see that the feather falls much slower. This is because the feather displaces the air around it.
Look closer at the feather. Notice that all the feather is are fibers sprouting from the quill. The air moves through these fibers slower and displaces the air around them. this is what helps birds to fly and glide.
Now observe someone in a flight suit. A flight suit has a type of fabric webbing in-between the arms and legs of the wearer. This allows them to glide through the air (when they gain lift) because the higher surface area of a light material displaces the air around it.
