Which of the following determine the chemical properties?
The chemical properties of an element are determined by the number of electrons in its atom, which in turn is determined by the number of protons.
Is copper oxide acidic or basic?
basic
Since copper (II) oxide is a metallic oxide so it is basic in nature.
What is the chemical formula for copper I oxide?
Cu₂OCopper(I) oxide / Formula
What are 4 chemical properties of copper?
Properties: Copper has a melting point of 1083.4 +/- 0.2°C, boiling point of 2567°C, specific gravity of 8.96 (20°C), with a valence of 1 or 2. Copper is reddish colored and takes a bright metallic luster. It is malleable, ductile, and a good conductor of electricity and heat.
What are 5 physical properties of copper?
The other key properties exhibited by copper and its alloys include:
- Excellent heat conductivity.
- Excellent electrical conductivity.
- Good corrosion resistance.
- Good biofouling resistance.
- Good machinability.
- Retention of mechanical and electrical properties at cryogenic temperatures.
- Non-magnetic.
What is the difference between CuO and Cu2O?
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. Many of the wood preservatives are made of copper. It is also used as a pigment to create different glazes.
What is the color of Cu2O?
red-coloured
Copper(I) oxide is one of the principal oxides of copper. It is an inorganic compound with the formula Cu2O. As for the colour, Copper(I) oxide is a red-coloured solid.
Which of the following is a physical property?
A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points.
