Both are p-type semiconductors, but Cu2O has a band gap of 2eV whereas CuO has a band gap of 1.2 eV — 1.9 eV. Cu2O is obtained by oxidation of copper metal or reduction of copper(II) solutions with sulfur oxide, whereas CuO is obtained by pyrometallurgical processes used to extract copper from ores.
What is the old name of CuO?Copper(II) oxide or cupric oxide is the inorganic compound with the formula CuO. A black solid, it is one of the two stable oxides of copper, the other being Cu2O or copper(I) oxide (cuprous oxide). As a mineral, it is known as tenorite.
What is Cu2O used for?Cuprous oxide is widely used in marine paints as a dye, fungicide and an antifouling agent. Industrially, rectifier diodes based on this material were used as early as 1924, long before silicon became the standard.
Is CuO more stable than Cu2O?Compare to Cu2O, CuO is more thermally stable materials because of the stability of CuO with high oxidation number . CuO has a band gap energy of 1.21 eV to 1.51 eV in the bulk with a brownish black appearance . ... Cu2O has a direct band gap of 2.0 eV to 2.60 eV which can absorb light up to the visible region .
Is the formula of this compound CuO or is it Cu2O?Copper(I) oxide or cuprous oxide is the inorganic compound with the formula Cu2O.

How do you explain AlCl3?Aluminium Chloride PropertiesAluminium chloride has a very low melting and boiling point.It sublimes at a temperature of 180°C.AlCl3 in a molten state is a poor conductor of electricity.The colour of aluminium chloride is white, but often it is contaminated with iron trichloride, which makes it yellow.More items...
Which is more stable Cu or Cu II?The important thing is that Cu(II) is d9, Cu(I) is d10. Since there is no Jahn Teller effect in Cu(I), no stabilisation occurs, so Cu(II) is more stable.

Did you mean to find the molecular weight of one of these similar formulas? When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula.
A common request on this site is to. To complete this calculation, you have to know what substance you are trying to convert.
The oxidation of copper(I) oxide, Cu2O(s) , to copper(II) oxide, CuO(s) , is an exothermic
The reason is that the molar mass of the substance affects the conversion. This site explains how to find molar mass.
We use the most common isotopes. This is how to calculate molar mass average molecular weightwhich is based on isotropically weighted averages. This is not the same as molecular mass, which is the mass of a single molecule of well-defined isotopes.
For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass. If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight Is CuO and Cu2O the same? the atom or group of atoms in the formula by the formula weight and multiplying by 100.
What is the diff between copper oxide and cupric oxide and cuprous oxide
Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction.
These relative weights computed from the chemical equation are sometimes called equation weights. Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance.
