When aqueous solutions of cadmium chloride and sodium sulfide are mixed, a precipitate of cadmium sulfide forms, leaving soluble sodium chloride in the solution. The corresponding equations are:

Molecular equation: CdCl₂(aq) + Na₂S(aq) ⇒ CdS(s) + 2 NaCl(aq)

Ionic equation: Cd²⁺(aq) + 2 Cl⁻(aq) + 2 Na⁺(aq) + S²⁻(aq) ⇒ CdS(s) + 2 Na⁺(aq) + 2 Cl⁻(aq)

Net ionic equation: Cd²⁺(aq) + S²⁻(aq) ⇒ CdS(s)

Let's consider the molecular equation for the reaction between aqueous cadmium chloride and aqueous sodium sulfide to form a precipitate of cadmium sulfide and aqueous sodium chloride. This is a double displacement reaction.

CdCl₂(aq) + Na₂S(aq) ⇒ CdS(s) + 2 NaCl(aq)

The ionic equation includes all the ions and insoluble species.

Cd²⁺(aq) + 2 Cl⁻(aq) + 2 Na⁺(aq) + S²⁻(aq) ⇒ CdS(s) + 2 Na⁺(aq) + 2 Cl⁻(aq)

The net ionic equation includes only the ions that participate in the reaction (not spectator ions) and the insoluble species.

Cd²⁺(aq) + S²⁻(aq) ⇒ CdS(s)

When aqueous solutions of cadmium chloride and sodium sulfide are mixed, a precipitate of cadmium sulfide forms, leaving soluble sodium chloride in the solution. The corresponding equations are:

Molecular equation: CdCl₂(aq) + Na₂S(aq) ⇒ CdS(s) + 2 NaCl(aq)

Ionic equation: Cd²⁺(aq) + 2 Cl⁻(aq) + 2 Na⁺(aq) + S²⁻(aq) ⇒ CdS(s) + 2 Na⁺(aq) + 2 Cl⁻(aq)

Net ionic equation: Cd²⁺(aq) + S²⁻(aq) ⇒ CdS(s)

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.

i believe the answer is c. "baking" is the gerund, while "baking blueberry muffins" would be the gerund phrase. hope this ! : )
