What happens to copper if it is left in water for a long period of time?

Copper left in water for a long period of time can undergo a process called oxidation, where it reacts with oxygen in the water to form copper oxide. This can cause the copper to turn green or develop a patina on its surface. Additionally, prolonged exposure to water can lead to corrosion of the copper over time.


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.


Is the solid left behind after a copper and sulfermixture is heatedf is it a compound or a element?

Copper powder reacts with molten sulphur to make copper(I) sulphide (a compound). 2Cu + S -> Cu2S Please see the link.


What appears to the left of copper?

To the left of copper appear nickel.


Is a bicycle left in the rain that becomes rusty a physical or chrmical weathering?

The rusting of a bicycle left in the rain is a form of chemical weathering. When the metal in the bicycle reacts with oxygen and water, it forms iron oxide, which is rust.


What does the oxygen sensor on a cars emission system do?

It most simply measures the Oxygen in the Exhaust gasses and produces a voltage the computer reads to determine how the engine is running. A certain amount of Oxygen left means it is burning the fuel as efficiently as possible. The chemical reasons and engineering is quite complex.


How many liters of nitrogen dioxide is produced when 34L of oxygen reacts with an excess of nitrogen monoxide?

When 34L of oxygen reacts with an excess of nitrogen monoxide, the stoichiometry of the reaction tells us that equal volumes of oxygen and nitrogen dioxide are produced. Therefore, 34L of oxygen will produce 34L of nitrogen dioxide.


What is the black residue left over after a magnesium combustion reaction?

The black residue left over after a magnesium combustion reaction is typically magnesium oxide (MgO), which forms when magnesium reacts with oxygen. The black color is due to the presence of the magnesium oxide compound.


Is Hydrogen produced when Magnesium reacts with copper sulfate solution?

The activity series of metals goes something like this: Lithium Potassium Barium Calcium Sodium Magnesium Aluminum Zinc Iron Nickel Tin Lead Hydrogen Copper Mercury .............and so on..... ps, I might have left some elements out....can't remember them all... Since magnesium is higher in the reactivity series of metals, it can replace copper in a reaction. Copper is lower in the activity series of metals therefore can not replace magnesium.


What element on the periodic table appears to the left of copper?

The element to the left of copper on the periodic table is nickel. Nickel has the atomic number 28, while copper has the atomic number 29.


What happens when copper burns?

When copper burns, it undergoes a chemical reaction with oxygen in the air to form copper oxide. This reaction releases heat and produces a colorful flame that is typically green or blue. Copper oxide residue is left behind after the burning process.
