Answer:

B: Transfer of protons

Explanation:

<em> An acid</em> by definition is a substance that can transfer a proton to another substance while a base is a substance that cab accept a proton.

<em>A proton</em> is a subatomic particle with a positive charge, present in the nucleus of an atom.

<em>An example</em> of an acid base reaction is dissolving sulfuric acid (H2SO4) in water

A proton from sulfuric acid is transferred to water. This proton transfer reaction between the strong acid and weak base,  converts water into hydronium ion and sulfuric acid into bisulfate ion.

Chemical reaction:

H2SO4+H2O → HSO4−+H3O+

How many amu are there in 8.3g?
jasenka [17]

Answer:

4.998 × 10²⁴ amu

Explanation:

Given data:

Mass of substance = 8.3 g

Atomic mass unit = ?

Solution:

The mass of one mole of substance is equal the gram per mole of that substance.

atomic mass unit = g/mol

For 8.3 g:

8.3 × 6.022×10²³

4.998 × 10²⁴ amu

The number 6.022 × 10²³ is called Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

Part A
KonstantinChe [14]

Answer:

The answer to your question is below

Explanation:

A.

[H₃O⁺] = 2 x 10⁻¹⁴ M

pH = ?

Formula

                                    pH = - log [H₃O⁺]

Substitution

                                    pH = - log [2 x 10⁻¹⁴]

Result

                                    pH = 13.7          

B.

[H₃O⁺] = ?

pH = 3.12

Formula

                                   pH = - log [H₃O⁺]

Substitution

                                   3.12 = - log [H₃O⁺]

                                   10^{-3.12} = [H_{3} O^{+}]

Result

                                  [H₃O⁺] = 7.59 M
