Question: Is CaO A Compound Or Element?

Is CaO acidic or basic?

Calcium oxide (CaO) , is a metal oxide.

Like other metal oxides it is a basic oxide because it dissolves in water to form calcium hydroxide..

Is CaO a metal or nonmetal?

CaO is metal oxide.

Is Naoh an ionic compound?

Sodium hydroxideSodium oxidanideSodium hydroxide/IUPAC ID

Is bacl2 an ionic compound?

Barium chloride is an ionic compound composed of one barium cation and two chlorine anions. In this case, chlorine will want to have a −1 oxidation state due to its high electronegativity.

Why is CaO called quicklime?

Calcium oxide, CaO, also known as lime or more specifically quicklime, is a white or grayish white solid produced in large quantities by roasting calcium carbonate so as to drive off carbon dioxide. At room temperature, CaO will spontaneously absorb carbon dioxide from the atmosphere,…

How many atoms are in Mgcl?

Magnesium dichloride is a magnesium salt comprising of two chlorine atoms bound to a magnesium atom.

What type of compound is CaO?

Calcium oxide (CaO), commonly known as quicklime or burnt lime, is a widely used chemical compound.

Why is CaO not soluble in water?

Explanation: The problem with this question is that you can’t really have an aqueous solution of calcium oxide, CaO , because this compound will react with water to form calcium hydroxide, Ca(OH)2 . Keep in mind that this reaction is highly exothermic!
