Answer:

A - Have no overall electric charge

Explanation:

Ideally, atoms of elements are chemically bonded to form molecules. A molecule is said to be a SIMPLE MOLECULE if it contains only a few atoms linked strongly together by covalent bonding. Examples of simple molecules are O2, CO2, I2, Cl2 etc.

The following properties are possessed by simple molecules:

- They have no overall electric charge

- They have low melting and boiling points due to the weak intermolecular forces that are easily overcomed when temperature is applied.

- Since they have no net charge, they do not conduct electricity.

- As their name implies, they rather have simple structures.

Complete the sentences to best explain the ranking.

Jobisdone [24]

Answer:

dipole-dipole forces, ion-dipole forces, higher molar mass, hydrogen bonding, stronger intermolecular forces

Explanation:

1. H₂S and H₂Se exhibit the following intermolecular forces: dipole-dipole forces and ion-dipole forces. These molecules have a bent geometry, thus, a dipolar moment which makes them dipoles. When they are in the aqueous form they are weak electrolytes whose ions interact with the water dipoles

2. Therefore, when comparing H₂S and H₂Se the one with a higher molar mass has a higher boiling point. In this case, H₂Se has a higher boiling point than H₂S due to its higher molar mass.

3. The strongest intermolecular force exhibited by H₂O is hydrogen bonding. This is a specially strong dipole-dipole interaction in which the positive density charge on the hydrogens is attracted to the negative density charge on the oxygen.

4. Therefore, when comparing H₂Se and H₂O the one with stronger intermolecular forces has a higher boiling point. That's why the boiling point of H₂O is much higher than the boiling point of H₂Se.

When barium hydroxide reacts with sulfuric acid, barium sulfate and water are produced. The balanced equation for this reaction

kompoz [17]

Answer: The balanced equation for given reaction is $Ba(OH)_{2}(aq) + H_{2}SO_{4}(aq) \rightarrow BaSO_{4}(s) + 2H_{2}O(l)$ .

Explanation:

A chemical equation which contains same number of atoms on both reactant and product side is called a balanced chemical equation.

For example, $Ba(OH)_{2}(aq) + H_{2}SO_{4}(aq) \rightarrow BaSO_{4}(s) + 2H_{2}O(l)$

Number of atoms on reactant side are as follows.

Ba = 1
O = 6
H = 4
S = 1

Number of atoms on product side are as follows.

Ba = 1
O = 6
H = 4
S = 1

Since atoms on both reactant and product side are equal. Therefore, this equation is balanced.

Thus, we can conclude that balanced equation for given reaction is $Ba(OH)_{2}(aq) + H_{2}SO_{4}(aq) \rightarrow BaSO_{4}(s) + 2H_{2}O(l)$ .
