What happens when a sodium ion is attracted to a chlorine ion

Answers

Answer: This will lead to the formation of ionic compound.

Explanation:

Ionic compound is defined as the compound which is formed from the complete transfer of electrons from one atom to another atom. The atom which looses its electron is known as electropositive atom and the atoms which gains electron is known as electronegative atom.

Covalent compound is defined as the compound which is formed when sharing of electrons takes place between the atoms forming a bond.

Sodium is the 11th element of the periodic table having electronic configuration:

This element will loose 1 electron to attain stable electronic configuration and forms ion.

Chlorine is the 17th element of the periodic table having electronic configuration:

This element will gain 1 electron to attain stable electronic configuration and forms ion.

Hence, an electron is transferred from sodium to chlorine and it results in the formation of an ionic compound.

Thus, when sodium ion is attracted to chlorine ion, it leads to the formation of an ionic compound.

What is the role of each of the following in the carbonc cycle? State an example of each. a. Primary producers
b. Secondary producers
c. Decomposers

Answers

Answer and Explanation:

a. Primary producers

Primary producers are organisms that are able to produce their own food, also known as autotrophs. The best example to illustrate this group are plants. They have a major role in the carbon cycle as they transform inorganic molecules from the atmosphere, such as CO2, into organic molecules like carbohydrates.

b. Secondary producers

Secondary producers are organisms that feed on primary producers, that is, they are heterotrophs (and herbivores), which are then consumed by predators. For example, caterpillars or rabbits. When these organisms respirate, they exhale carbon dioxide, which is used by primary producers in the carbon cycle.

c. Decomposers

Decomposers are organisms that consume and break down organic matter such as dead animals, feces, and leaves. For example, fungi and bacteria. Through this process, they release CO2 and methane into the atmosphere, making carbon dioxide available for plants to carry out photosynthesis.

Answer:

The role of each of the following in the carbon cycle with example is discussed as:

a. Primary Producer:

                                    Primary producers are those ones who take inorganic molecules like carbon dioxide and convert them into organic molecules like carbohydrates. For example: Plants, autotrophs.

b. Secondary Producer:

                                          Secondary producers are mainly herbivores like elephants, provides food for carnivores, consumes primary producer and they release carbon dioxide into the atmosphere.

c. Decomposers:

                             Decomposer are those ones who break down the dead materials of plants or animals and release energy back to the nonliving environment like soil, water, air etc. The example include earthworms.
