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.

Why is copper a much denser material than oxygen?
Copper has a higher atomic weight and a greater number of protons and neutrons in its nucleus compared to oxygen, making it denser. Additionally, the atomic arrangement in copper is more tightly packed than in oxygen, contributing to its higher density.
Is most of the volume occupied by a piece of copper is taken up by the volume of the copper nuclei?
No, most of the volume occupied by a piece of copper is taken up by the electrons surrounding the copper nuclei. The electrons occupy a much larger volume compared to the nuclei due to their lower mass and ability to move more freely within the atomic structure.
How much carbon dioxide is formed when 24.0g of carbon is reacted with 100.0g of oxygen?
24.0 g of carbon reacts with 64.0 g of oxygen to form 88 g of carbon dioxide.
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.
How much copperII oxide would be produced from 25g of copper when reacted with oxygen gas?
31.3 g CuO
A certain alloy contains 5.25 percent copper How much copper is there in a piece weighing 200 pounds?
In a piece weighing 200 pounds and containing 5.25% copper, there would be 10.5 pounds of copper (200 pounds x 0.0525).
Why is copper a much denser material than oxygen?
Copper has a higher atomic weight and a greater number of protons and neutrons in its nucleus compared to oxygen, making it denser. Additionally, the atomic arrangement in copper is more tightly packed than in oxygen, contributing to its higher density.
Why magnesiam oxide is not attacked by atmospheric oxygen?
The magnesium has reacted already with as much oxygen that it can (1 atom of oxygen to 1 atom of magnesium). There are no spare magnesium atoms left so the reaction has stopped, There is no energetically favourable way that further oxygen atoms can react.
What is 22k rate of gold?
The Karet weight of a piece of gold states how much of the piece is actual gold and not silver or copper. A piece that is 22k means that it is 91. 6% pure gold.
Is most of the volume occupied by a piece of copper is taken up by the volume of the copper nuclei?
No, most of the volume occupied by a piece of copper is taken up by the electrons surrounding the copper nuclei. The electrons occupy a much larger volume compared to the nuclei due to their lower mass and ability to move more freely within the atomic structure.
How much oxygen does one piece of paper give us?
None. It's an inert object.
How much carbon dioxide is formed when 24.0g of carbon is reacted with 100.0g of oxygen?
24.0 g of carbon reacts with 64.0 g of oxygen to form 88 g of carbon dioxide.
How much is a 1974 silver 50 cent piece worth?
50 cents. It's made of copper-nickel, not silver.
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
