Answer:
A. Na₂SO₄ and HCl
C. Polar solutes are soluble in polar solvents but are insoluble in non-polar solvents Non-polar solutes are insoluble in polar solvents but are are soluble in non-polar solvents
Ionic solutes are soluble in polar solvents but are insoluble in non-polar solvents.
Like dissolves like simply means that molecules of substances having similar chemical properties dissolve in each other
Explanation:
A. Ionic substances like Na₂SO₄ are composed of charged particles called ions. These ions are either positively charged or negatively charged, therefore, they are attracted to substances of opposite charges. Also, polar molecules like HCl contains two oppositely charged ends. A polar solvent consists of molecules with two oppositely charged ends, therefore, ionic substances as well polar substances dissolve in them according to the concept of like dissolves like.
Gasoline being non-polar will only dissolve in like substances, polar solvents.
C. Polar solutes are soluble in polar solvents but are insoluble in non-polar solvents Non-polar solutes are insoluble in polar solvents but are are soluble in non-polar solvents
Ionic solutes are soluble in polar solvents but are insoluble in non-polar solvents.
The statement "Like dissolves like" simply means that molecules of substances having similar chemical properties dissolve in each other. For example gasoline, a non-polar substance will dissolve only in a non-polar solvent like kerosene. Also, HCl, a polar molecule will dissolve in a polar solvent like water.
ionic bond is formed between ca and cl forming molecule cacl2 ca has 2 velancy and cl has one velancy (ca has 2 electrons in its outer most shell while cl has 1 electron vecancy in its outermost shell). So ca would make bond with 2 cl atoms
B) Equal to the number of protons
Mass = moles x Mr
So in this case the moles =1
And the Mr equals =11
So you would do - 11x1= 11grams
Aluminum chloride is formed in the reaction of aluminum with hydrochloric acid. The formula of aluminum chloride is AlCl₃.
Aluminium chloride, additionally referred to as Aluminium trichloride, is an inorganic compound with the formula AlCl₃. It bureaucracy hexahydrate with the system [Al(H₂O)₆]Cl₃, containing six water molecules of hydration. Each are colourless crystals, however samples are regularly contaminated with iron(III) chloride, giving a yellow shade.
Aluminum Chloride is used to control immoderate sweating. This medicinal drug can be used for other purposes; ask your fitness care provider or pharmacist when you have questions.
Aluminum chloride is corrosive and nerve-racking to the eyes, skin, and mucous membranes. Can be dangerous if swallowed. Ingestion of big quantities may also motive phosphate deficiency. Aluminum chloride is a compound of aluminum and chloride it truly is widely utilized in petroleum refining and the producing of many products. similarly, antiperspirants and cosmetic astringents use this compound.
