Which of the following pairs consists of a weak acid and a strong base? (1 point)
notka56 [123]

Answer:

acetic acid, sodium hydroxide

Explanation:

A strong acid is an acid that ionizes in water to give all its hydrogen ion. Weak acid only ionize to a certain degree. Acetic acid (CH3COOH) only ionize to give one hydrogen ion despite having other hydrogen atom. This account for its weak nature as an acid as shown below:

CH3COOH <=> H^+ + CH3COO^-

A strong base is a base that ionizes in water to give all it hydroxide ion. Sodium hydroxide(NaOH) ionizes to give all its hydroxide ions. This make it a strong base as shown below;

NaOH <=> Na^+ + OH^-

How do you find a theoretical mass? Is there a difference between theoretical mass and theoretical yield?
swat32

Theoretical yield is the quantity of a product obtained from the complete conversion of the limiting reactant in a chemical reaction. It is the amount of product resulting from a perfect chemical reaction and thus not the same as the amount you'll actually get from a reaction.

Why is it difficult to classify hydrogen was a metal or non metal
sladkih [1.3K]

Answer:

Because of its ability to create cations, hydrogen is a nonmetal that belongs to the same category as metals. Despite its presence in Group I (alkali metals) of the periodic table, hydrogen is not considered a metal.

Hydrogen is categorized as a nonmetal. This is due to the fact that it behaves like a non-metal.

Its very confusing lol

Have a nice day
