For c2h3o2−, write an equation that shows how the anion acts as a base.

Explanations:- Acetate ion is a conjugate base of a weak acid(acetic acid). From Bronsted-Lowry concept of acid and base, "Acids are proton donor where as bases are proton acceptors.
To work as a base, acetate ion would be accepting a proton. Water is an amphoteric compound means it could act as an acid as well as a base. So, let's write the reaction of acetate ion with water to show how it acts as a base.
In the above reaction, acetate ion has accepted a proton from water means its a base and since water has donated a proton so its an acid.
Acetic acid is the conjugate acid of acetate ion and hydroxide ion is the conjugate base of water.

So we know that the equation for density is:
where D is the density, m is the mass in grams, and V is the volume in mL.
So since we know two of the variables, mass and density, we can solve for the volume:
Therefore, the volume of this urine sample is 144.12mL.
Answer:
A.
Explanation:
Hello there!
In this case, for us to figure out the appropriate equilibrium expression, it will be firstly necessary for us to recall the law of conservation of mass which states that the equilibrium constant of an equilibrium chemical reaction is written by dividing the products and reactants and including the stoichiometric coefficients as exponents. In such a way, for the given reaction, we will have:
As N2O is the product whereas N2 and O2 are reactants; thus, the equilibrium expression will be A.
