Add water 50 ml to 50 ml 12 M
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.

They are very stable. they have a "full table" so to speak. they have no valance electrons. they do not give electrons and they do not take them either. there are very few if an elements that can be paired with noble gasses
Answer:
The answer to your question is 159.0 grams
Explanation:
data
mass of K₂O = ?
mass of K = 132 g
Process
1.- Balance the chemical reaction
Chemical reaction
K(s) + O₂ ⇒ K₂O
Reactants Elements Products
1 K 2
2 O 1
This reaction is unbalanced
4K(s) + O₂ ⇒ 2K₂O
Reactants Elements Products
4 K 4
2 O 2
Now the reaction is balanced
2.- Calculate the mass of K₂O
Atomic mass of K = 39 x 4 = 156 g
Molar mass of K₂O = 2[(39 x 2) + 16] = 188 g
156 g of K ------------------ 188 g of K₂O
132 g of K ----------------- x
x = (132 x 188) / 156
x = 159.0 grams
