Is calcium oxide a covalently bonded compound or a ionically bonded compound?
Calcium oxide is an ionically bonded compound that contains equal numbers of calcium cations with a charge of +2 and oxide anions with a charge of -2.
Water bond ionically or covalently?
Water contains hydrogen and oxygen, which are both nonmetals, therefore water is a covalent compound.
How many moles of O2- ions are in 0.65 moles of aluminum oxide?
The formula for aluminum oxide is Al2O3, which means that, if aluminum oxide is ionically bonded, every formula mass of aluminum oxide contains three O-2 ions. In this instance, 0.65 formula masses of aluminum oxide would contain 3 X 0.65 or 1.95 moles of O2-. If aluminum oxide were covalently bonded, it would not contain any O-2 ions.
What type of compound is Cl2O?
Chlorine(I) Oxide is a covalently bonded molecule which has the same geometry as in water molecule.
What is the difference between CaO and CaOH2?
CaO is calcium oxide. It consists of one calcium ion (Ca2+) ionically bonded to one oxide ion (O2-). It is commonly referred to as lime or quicklime. The second compound is properly written as Ca(OH)2 with the OH in parentheses to indicate that there are two hydroxide (OH-) ions rather than just two hydrogen atoms. Ca(OH)2 is calcium hydroxide consists on one calcium ion (Ca2+) bonded totwo hydroxide ions (OH-). It forms when CaO reacts with water. It is commonly known as slaked lime or lime water.
Is calcium oxide a covalently bonded compound or a ionically bonded compound?
Calcium oxide is an ionically bonded compound that contains equal numbers of calcium cations with a charge of +2 and oxide anions with a charge of -2.
Water bond ionically or covalently?
Water contains hydrogen and oxygen, which are both nonmetals, therefore water is a covalent compound.
What compounds contains one or more covalent bonds Choices Carbon Dioxide Sodium chloride Calcium Oxide Barium Bromide Cesium Oxide?
Carbon dioxide is covalently bonded.
What kind of oxide is formed when a nonmetal like sulfur is burned?
A covalently bonded oxide is created.
Is calcium oxide an ionic bonded compound?
Calcium oxide is an ionic compound.
How many moles of O2- ions are in 0.65 moles of aluminum oxide?
The formula for aluminum oxide is Al2O3, which means that, if aluminum oxide is ionically bonded, every formula mass of aluminum oxide contains three O-2 ions. In this instance, 0.65 formula masses of aluminum oxide would contain 3 X 0.65 or 1.95 moles of O2-. If aluminum oxide were covalently bonded, it would not contain any O-2 ions.
Is sulfur oxide a molecule or part of an ionic solid?
Sulfer oxide is covalently bonded - so no, it is not an ionic solid.
When oxygen is bonded to a metal it forms?
The oxidation of a metal produces a metal oxide. For example, calcium + oxide -> calcium oxide
What type of compound is Cl2O?
Chlorine(I) Oxide is a covalently bonded molecule which has the same geometry as in water molecule.
Is calcium oxide a convalenty bonded chemical?
No, it is an ionic compound.
Are bonded calcium and oxygen atoms an element compound or mixture?
A compound, and it's name would be calcium oxide.
What is the name of the compound CaO3?
CaO is Calcium Oxide also known as quicklime.The systematic name of this compound is Calcium Oxide.
