Which of the following is the conjugate acid of H2P04- ?
A. HAP04
O B. PO 3-
O C. HP04-2
O D. H3PO4

Answers

Answer:

phosphoric acid H3PO4

The conjugate acid of H₂PO⁴⁻ is H₃PO₄. Therefore, option D is correct.

A conjugate acid is a species that is formed when a base accepts a proton (H⁺). It is the species that is one proton (H⁺) more acidic than the original base.

The base is the species that can accept a proton (H⁺), and the conjugate acid is the species that is formed when the base accepts the proton. The conjugate acid has one additional proton compared to the base.

Conjugate acids play an important role in acid-base reactions as they are formed when bases accept protons, and they can donate protons in subsequent reactions to regenerate the original base.

B. pure substance made of two or more elements
C. can be represented by a chemical formula
D. different samples have different properties

Answers

Answer:

I think it's D

sorry if I'm wrong.

Explanation:

Options that are not characteristics of compound in the question is D. different samples have different properties.

A compound can be regarded as a substance which is formed by chemical  combination of two or more elements.Examples of compound are water ( H2O), Sodium chloride ( NaCl)

Some of the properties of a compound are;

A compound will always has a different properties which is different from the properties of each of the elements making up the compound.A compound are formed as a result of  two or more elements that combined chemically.A compound can be identified with its chemical formula.

Therefore, option D is correct because a compound will only has its own properties not that

What are covalent bonds

Answers

Answer:

A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding

How does the atomic mass of the atom change when an electron is added or removed?

Answers

If you could magically make two neutrons in the nucleus of an atom disappear, the atomic number and the electrical charge of that atom would remain unchanged. Neutrons do not carry an electrical charge so adding or removing them from the nucleus does not change the electrical charge of the nucleus. It does, however, change the mass of the nucleus. Adding or removing neutrons from the nucleus are how isotopes are created.

Protons carry a positive electrical charge and they alone determine the charge of the nucleus. Adding or removing protons from the nucleus changes the charge of the nucleus and changes that atom's atomic number. So, adding or removing protons from the nucleus changes what element that atom is! For example, adding a proton to the nucleus of an atom of hydrogen creates an atom of helium. (Actually, a few neutrons have to be added as well to make the new nucleus stable, but the end result is still helium.) Keep in mind that atoms, by definition, are electrically neutral and always contain the same number of protons and electrons.

When 3.00 grams of methane, CH,, reacts according to the balanced equation below, how many molecules of water are produced?
CH, + 202 - CO2 + 2H20

Answers

Answer:

2.41×10²³ molecules of water

Explanation:

Given data:

Mass of methane = 3 g

Molecules of water formed = ?

Solution:

Chemical equation:

CH₄ + 2O₂    →     CO₂  + 2H₂O

Number of moles of methane:

Number of moles = mass/ molar mass

Number of moles = 3 g/ 16 g/mol

Number of moles = 0.2 mol

Now we will compare the moles of water with methane.

               CH₄           :              2H₂O

                  1              :                  2

                0.2            :             2 × 0.2 = 0.4 mol

Molecules of water:

1 mole = 6.022×10²³ molecules of water

0.4 mol ×6.022×10²³ molecules of water / 1mol

2.41×10²³ molecules of water
