Answer: Option (C) is the correct answer.

Explanation:

A compound is a substance that contains atoms of two or more different elements which are chemically combined together in a fixed ratio by mass.

For example, NaCl, CO_{2}, Mg(OH)_{2} etc are all compounds.

Atoms of a compound can be separated by chemical means.

Hence, we an conclude that the atoms can only combine in fixed ratios, and they can only be separated by a chemical change, correctly describes a compound.

KATRIN_1 [288]

1. a group of resources treated as a single entity that accepts a combination of materials and instructions to add value through a series of operations; may be either automated or manual.

2. a group of cells that have similar structure and that function together as a unit. A nonliving material, called the intercellular matrix, fills the spaces between the cells.

3. a differentiated structure (such as a heart, kidney, leaf, or stem) consisting of cells and tissues and performing some specific function in an organism.

4. a group of organs that work together to perform a certain function in an organism's body.

5.  complex systems of chemical compounds that, through interaction and environment, play a wide variety of roles. Organisms are semi-closed chemical systems. Although they are individual units of life (as the definition requires), they are not closed to the environment around them.

6. the significance of the charge hosted by a particular atom in a molecule becomes obvious

7. an interacting group of various species in a common location

8. an ecological community comprised of biological, physical, and chemical components

Iron iii chloride ammonium hydroxide balanced equation, complete ionic equation, net ionic equation
Vladimir [108]
Iron III Chloride has a chemical formula of FeCl₃, while ammonium hydroxide has a chemical formula of NH₄OH. 

The <em>balanced equation</em> would be:

FeCl₃ (aq) + 3 NH₄OH (aq) → Fe(OH)₃ (s) + 3 NH₄Cl (aq)
The precipitate is Fe(OH)₃ or iron iii hydroxide.

To find the <em>complete ionic equation</em>, dissociate the compounds in aqueous phases into their ionic forms:

Fe³⁺ + Cl⁻ + NH₄⁺ + 3 OH⁻ -->  Fe(OH)₃(s) + NH₄⁺ + Cl⁻ 

To find the <em>net ionic equation</em>, cancel out like ions that appear both in the reactant and product side:

Fe³⁺ +  3 OH⁻ -->  Fe(OH)₃
