Answer:

CH3COOH will be the acid, because it is the stronger acid.

Explanation:

When an acid deprotonates in a solution, an equilibrium reaction will occur between the protonated form and the deprotonated form (conjugate base) of it. The equilibrium is characterized by the value of Ka, the equilibrium constant, which is the multiplication of the concentration of the products divided by the concentration of the acid.

As higher is the value of Ka, more acid is deprotonated, and stronger will be the acid. The value of pKa = -logKa, and so, as higher is the Ka, as low is the pKa. Thus, strong acids have low pKa values.

In the reaction of CH3COOH and H2O, the first one has a low value of pKa, so it is a strong acid. The water is a substance that can work as an acid or as a base, and, because of the other substance is a strong acid, it works as a base.

What was John Dalton's contribution to the development of the atomic theory?
Lorico [155]

John Dalton made some hypothesis about the structure of atom. He proposed that matter is composed of great number of indivisible particles called atoms they can neither be destroyed nor be created.

<h3>What is atomic theory?</h3>

There are different theories regarding the structure and electronic properties of an atom. Many scientists contributed to the modern theory of atomic structure in which John Dalton was first to mention the word atom.

According to Dalton' theory, matter is composed of indivisible particles called atoms. Atoms can neither be created nor be destroyed. All the atoms of the same element are identical in all aspects.

Atoms of different elements are different and the compounds are formed by the combination of atoms.  Dalton's theory provided a sound basis for the laws of chemical combination and also several properties of gases and liquids known at that time.

However, he could not explain the reason for chemical combination of atoms and did not give any idea about the existence of isotopes and isobars.

Hence, the main aspects of Dalton's theory was the indivisibility of atoms and the chances of chemical combination.
