How much oxygen reacted with the piece of copper?
The amount of oxygen reacting with copper can be determined by the reaction stoichiometry. For example, in the reaction of copper with oxygen to form copper oxide, two moles of oxygen react with one mole of copper. From the given amount of copper and assuming all the copper reacted to form copper oxide, you can calculate the corresponding amount of oxygen that reacted with the copper.
What is the chemical name of the product formed when copper reacts with a gas in air?
When the product is with oxygen it will be copper oxide CuO. If it is with nitrogen it is copper nitrate.
When 127 g of copper reacts with 32 g of oxygen gas to form copper (II)oxide no copper or oxygen is left over. how much copper (II) oxide is produced?
Using the given masses, calculate the moles of each reactant. The limiting reactant will be the one that produces the least amount of product, which is copper. Convert the moles of copper to moles of copper (II) oxide using the balanced chemical equation. Then, convert the moles of copper (II) oxide to grams to find the mass produced.
Which is harder-------------- copper or diamond?
Diamond is much harder than copper. On the Mohs hardness scale (higher numbers are harder), diamond is a 10 and copper is somewhere between 3 and 4.
How much temperature is needed to form copper ii oxide?
Copper(II) oxide is formed when copper metal is heated in the presence of oxygen at a temperature around 700-800°C. This high temperature is required to provide the energy for the copper to react with the oxygen and form the oxide compound.

Is clay denser than sponge?
Yes, clay is denser than sponge. Clay is a natural mineral material that is compact and heavy, while sponge is a lightweight, porous material that is less dense.
Which material is denser feather or iron plate?
Iron plate is denser than feather. Densities of materials are typically measured in terms of mass per unit volume, so iron plate, being a metal, is much denser than a feather, which is made of lightweight keratin.
Why coppers is commonly used in conductors?
Silver and gold are better conductors, but as copper is more abundant and is also a much cheaper material, copper is more commonly used.
How much copperII oxide would be produced from 25g of copper when reacted with oxygen gas?
31.3 g CuO
What are the Weaknesses of copper?
So far only a couple have been found.high temperaturewhen mixed with with a lot of oxygen ( Co2 ) it can be very explosivetoxicity- when there too much copper in a small space
What is the chemical name of the product formed when copper reacts with a gas in air?
When the product is with oxygen it will be copper oxide CuO. If it is with nitrogen it is copper nitrate.
Does copper sink in water?
Copper does not sink in water.. An object with higher density than water sinks while an object with lower density than water floats..

Why is copper oxide called copper oxide?
Is world-widely used in the wires for energy transportation by the electrical companies of every country, for the telecommunications wires too. Many alloys are consisting of copper, such as bronze. A major factor for copper's importance is its availability as a natural resource and therefore its seniority as a metal in use. Other factors are its malleability and its low melting point.
Can a planet be denser than its star?
Yes, the Earth is much denser than our sun.
