anzhelika [568]3 years ago
5 0
Mole solute=Molar concentration(mol/L)*Volume solution(L)

250.0 mL=0.2500L
2.5M=2.5 mol/L
mole solute=2.5 mol/L*0.2500L= 0.625 ≈ 0.63 mol

Choose the weaker acid in each of the following pairs:H₂SO₃ or H₂SO₄
WINSTONCH [101]

H₂SO₃ is weaker acid than  H₂SO₄.

The bonding power of an acid is typically influenced by the size of the "SO₄" atom; the smaller the "SO₄" atom, the stronger the H-A bond. The atoms get larger and the bonds get weaker as you proceed down a row in the Periodic Table, strengthening the acids.

<h3>Describe acid.</h3>

The term "acid" refers to any molecule or ion that can donate a proton (a Brnsted-Lowry acid) or establish a covalent bond with an electron pair (a Lewis acid). The first class of acids is the proton donors, also known as Brnsted-Lowry acids.

Its chemical name is lysergic acid diethylamide, or LSD as it is more often known. Because it has a potent hallucinogenic impact, using it could alter how you see the world and its objects. The effects of LSD are referred to as tripping.

The term "acid" is frequently used to denote aqueous solutions of acids with a pH lower than 8, even though the technical meaning of the term only pertains to the solute.

match the number of negative charges to the number of positive charges to make each combination balanced (see image for answer)
BartSMP [9]

Answer : The correct match is:

1 positive charge = 1 negative charge

2 positive charges = 2 negative charges

3 positive charges = 3 negative charges

Explanation :

As we now that there are three subatomic particles which are protons, electrons and neutrons.

The protons and neutrons are located inside the nucleus and electrons are located around the nucleus.

The protons are positively charged, the electrons are negatively charged and neutrons are neutral.

As we know that all the things are made up of charges and opposite charges attract to each other.

In a neutral atom, the positive charges and negative charges are balanced in an object. That means, in neutral atom the number of positive charges are equal to the negative charges.

So we can say that:

1 positive charge = 1 negative charge

2 positive charges = 2 negative charges

3 positive charges = 3 negative charges
