IT is called Iron(iii)oxide
Some similarities between deserts and rainforests are that they support complex ecosystems, are powered by the sun/photosynthetic plants, are dangerous/mostly uninhabitable for humans, due to both conditions and wildlife, and are found mostly in the tropics
Aqueous Solution - The expected precipitate would consist of Cu(OH)2.
What is aqueous solution?
An aqueous solution is one in which water serves as the solvent. Chemical equations typically illustrate it by adding (aq) to the appropriate chemical formula. For instance, Na+(aq) + Cl would be used to represent a solution of table salt, as well as sodium chloride (NaCl), throughout water (aq). The word aqueous, which derives from the word aqua, means that it is dissolved in or related to water. Water is a common solvent in chemistry due to its superior solvent properties and natural abundance. Since water is frequently used as a solvent in experiments, unless the solvent is specified, the word "solution" refers to an aqueous solution. A solution wherein the solvent is a liquid but not water is referred to as a non-aqueous solution.
