What happens when copper vessel is exposed to moist air for a long time give the chemical reaction that takes place?
When a copper vessel is exposed to moist air for a long time, it undergoes a chemical reaction with oxygen and moisture to form copper oxide (CuO) and eventually copper carbonate (CuCO3). Both of these are easily recognizable as a greenish layer of patina that forms on the surface of the copper.
Is a form of green carbonate when exposed to moist air a physical property or chemical property?
This is a chemical property. The reaction of green carbonate with moist air to form a different substance involves a change in the chemical composition of the substance, indicating a chemical reaction.
What colour does moist red litmus paper turn in magnesium oxide?
Moist red litmus paper will turn blue when exposed to magnesium oxide because magnesium oxide is a basic compound. The red litmus paper will change color to blue to indicate the presence of a base.
What is the difference between efflorescent and hygroscopic?
Efflorescent substances (e.g. sodium carbonate decahydrate, copper(II) sulfate pentahydrate) lose some or all of their water of crystallisation when exposed to the air. Hygroscopic substances (e.g. concentrated sulphuric acid, calcium oxide) absorb water from the atmosphere but do not dissolve in it.
How Corrosion of iron in presence of moist air?
When iron is exposed to moist air, it can undergo a chemical reaction known as corrosion. The moisture in the air reacts with iron to form iron oxide, also known as rust. This process is accelerated in the presence of salt or pollutants in the air, which act as catalysts for the corrosion of iron. Regular maintenance and protective coatings can help prevent corrosion of iron in moist air environments.

What happens when copper utensils are exposed to prolonged atmospheric air?
When copper is exposed to moist air for a long time, it acquires a dull green coating. The green material is a mixture of copper hydroxide and copper carbonate. This film called 'verdigris' protects the underlying metal from further damage. 2Cu + H2O+CO2 + O2 Cu(OH)2 + CuCO3
Does copper turn green?
yes copper turns green when exposed to moist air for a long time as green metal is a mixture of copper hydroxide and copper carbonate 2CU+H2O+O2 --> CU(OH)2+CUCO3
What element turns white when exposed to air?
Phosphorus is an element that turns white when exposed to air. When pure, it is a colorless and transparent waxy solid.
When moist air is heated in a air tight vessel what happens?
When moist air is heated in an airtight vessel, the temperature of the air increases, causing the water vapor to evaporate more readily, which can lead to an increase in humidity. If there is no way for the water vapor to escape the vessel, it will remain inside as part of the air mixture.
What happens when oygen and copper react?
You get copper (I) oxide which is red and copper (II) oxide that is black. Copper (II) oxide is more stable. In moist air it also forms copper hydroxide and copper carbonate giving the known green color.
How do you dress the exposed intestines or organ?
You must cover it with moist saline dressings.
Which compound is formed when Fe is exposed to moist air?
Iron rust (iron oxide) is formed when iron is exposed to moist air due to the process of oxidation.
What do you think will happen to the moist cloth as the wet bulb thermometer is exposed to air?
The moist cloth will start to cool
What is the balanced equation of copper producing copper oxide due to the prescence of moist air?
2Cu + O2 yields 2CuO
What are the specifications of a good copper mine?
Well that a good question the most important part of a good copper mine is whether the surrounding area is wet and moist
Why copper articles becomes green on exposure to moist air?
they turn green due to oxidation. in iron it is red and called rust, in copper it is called patina
