Answer:

1) Covalent bond, in chemistry, the interatomic linkage that results from the sharing of an electron pair between two atoms. The binding arises from the electrostatic attraction of their nuclei for the same electrons.

2)A molecule is the smallest particle in a chemical element or compound that has the chemical properties of that element or compound. Molecules are made up of atoms that are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons among atoms.

3)Hydrogen (H2), oxygen (O2), and chlorine (Cl2) molecules, for example, each contains two atoms. Another form of oxygen, ozone (O3), has three atoms, and sulfur (S8) has eight atoms. All elemental molecules are made of atoms of a single element.

Which of the following is a definition of a base? O a. behaves as a catalyst. O b. accepts H ions from acids. Oc. turns cloudy w

yan [13]

Answer: b. accepts $H^+$ ions from acids

Explanation:

According to Arrhenius concept, a base is defined as a substance which donates hydroxide ions $(OH^-)$ when dissolved in water and an acid is defined as a substance which donates hydronium ions $(H_3O^+)$ in water.

According to the Bronsted Lowry conjugate acid-base theory, an acid is defined as a substance which donates $H^+$ ions and a base is defined as a substance which accepts $H^+$ ions.

$NH_3+H_2O\rightarrow NH_4^++OH^-$

Here water is donating $H^+$ ions, and thus act as acid and ammoia $NH_3$ is accepting $H^+$ ions from water and thus is a base.

According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.

Thus base is a substance which accepts $H^+$ ions from acids.

Compared to a solution with a ph of 6, the hydronium ion concentration of a solution with a Ph of 4 has how many more times the

Alexxx [7]

Answer: The hydronium ion concentration of a solution with a pH of 4 is 100 times more than the the hydronium ion concentration of a solution with a pH of 6

Explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration.

$pH=-\log [H^+]$

1. Solution with pH of 6

$6=-\log [H^+]$

$[H^+]=10^{-6}$

2. Solution with pH of 4

$4=-\log [H^+]$

$[H^+]=10^{-4}$

$\frac{H^+_4}{H^+_6}=\frac{10^{-4}}{10^{-6}}=10^{2}={100}$

${H^+_4}=100\times {H^+_6}$

Thus the hydronium ion concentration of a solution with a pH of 4 is 100 times more than the the hydronium ion concentration of a solution with a pH of 6
