What else can I help you with?
Does beryllium react with cold water?
Be (beryllium) does not react with water , steam or oxygen even at red heat. because it has a strong resistant layer of oxide on it's surface (impenetrable coating)which lower it's reactivity.
Is lactose a element or compound?
Ionic means the elements are joined by connecting with electrons, and everything is molecular. Molecular means something to do with molecules, which is a single compound, which can be carbon dioxide to, zinc oxide. Elements is a single pure element from the Periodic Table, like oxygen,carbon, florine, zinc, iron etc. Compound is a group of these elements bonded through either ionic or covalent bonding. So lactose is just a compound that has joined both ionically and covalently
When oxygen is bonded to a metal it forms a n compound when it is bonded to a nonmetal it forms a n compound?
When oxygen is bonded to a metal, it forms an oxide compound. When oxygen is bonded to a nonmetal, it forms an oxide compound as well. Oxygen can form both ionic and covalent bonds with different elements depending on their electronegativity.
What is the formula formula for lead IV oxide?
The formula for lead(IV) oxide is PbO2. It is composed of one lead atom bonded to two oxygen atoms.
How much elemental Calcium is there in Calcium oxide?
There is no elemental calcium in calcium oxide. Calcium oxide is a compound made up of calcium and oxygen atoms bonded together. When calcium oxide reacts with water, it forms calcium hydroxide, which contains calcium ions but not elemental calcium.
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.
Is calcium oxide covalently bonded or ionically?
Calcium is a metal with an electronegativity of 1.0 and oxygen is a nonmetal with an electronegativity of 3.5. The electronegativity difference is 2.5, and anything over 1.7 indicates an IONIC BOND.
What kind of oxide is formed when a nonmetal like sulfur is burned?
A covalently bonded oxide is created.
Is sulfur oxide a molecule or part of an ionic solid?
Sulfer oxide is covalently bonded - so no, it is not an ionic solid.
Water bond ionically or covalently?
Water molecules bond covalently, where the oxygen atom shares electrons with the two hydrogen atoms to form a stable molecule. The interaction between water molecules, known as hydrogen bonding, is a weak form of intermolecular bonding that is responsible for many of water's unique properties.
Is Nitrogen oxide molecular of ionic?
Nitrogen oxide is a molecular compound, not an ionic compound. It is composed of nitrogen and oxygen atoms bonded together covalently.
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 compounds contains one or more covalent bonds Choices Carbon Dioxide Sodium chloride Calcium Oxide Barium Bromide Cesium Oxide?
Carbon Dioxide is the compound that contains covalent bonds. It is composed of one carbon atom covalently bonded to two oxygen atoms. Sodium chloride, Calcium Oxide, Barium Bromide, and Cesium Oxide contain ionic bonds.
Monatomic anions that are ionically or covalently bonded use which suffix for naming?
Most often "ide", but "ate" and "ite" are also common when the compound includes an anion containing oxygen bonded to some other element.
What type of oxide is silicon dioxide?
Giant covalent molecule. It is an acidic oxide
Is magnesium oxide a compound or a molecule?
Magnesium oxide is a compound because it is formed from a chemical combination of magnesium and oxygen atoms. It does not consist of discrete molecules like covalently bonded compounds, but rather ions held together by ionic bonds.
Does beryllium react with cold water?
Be (beryllium) does not react with water , steam or oxygen even at red heat. because it has a strong resistant layer of oxide on it's surface (impenetrable coating)which lower it's reactivity.
