What chemical change occurs when a banana peel turns brown in the air?
When a banana peel turns brown in the air, a chemical change called oxidation occurs. This is due to the exposure of enzymes in the banana to oxygen in the air, which causes them to react and produce brown pigments.
Why does olive brine turn brown after opening?
Olive brine turns brown after opening due to oxidation and the natural breakdown of the olive pigments. Exposure to air and light can accelerate this process. It is a natural reaction and does not affect the taste or safety of the brine. Shake well before use to redistribute the flavors.
What kinda of chemical change do you think occurs when a banaana peel turns brown in the open air?
Oxidation
Why does paper turn brown when old?
Paper turns brown when old due to the oxidation of lignin, a natural polymer found in wood fibers used to make paper. Exposure to light, air, and high humidity speeds up this process, leading to a chemical reaction that darkens the paper over time.
A sliced apple turning brown is exhibiting the ability to react with oxygen a physical property?
The sliced apple turning brown is a chemical change, not a physical property. It is a result of a chemical reaction between the compounds in the apple and oxygen in the air, leading to the formation of new compounds that give the apple its brown color.
What chemical change occurs when a banana peel turns brown in the air?
When a banana peel turns brown in the air, a chemical change called oxidation occurs. This is due to the exposure of enzymes in the banana to oxygen in the air, which causes them to react and produce brown pigments.
Why does Guacamole turn dark?
It oxidizes and turns brown quickly after exposure to air. To prevent this, lime or lemon juice can be added to avocados after they are peeled.
What is phenolsulfonate?
Phenolsulfonate is a colorless to white crystalline solid which turns pink on exposure to air.
Does air effect if an apple turns brown if so how?
The oxygen in the air causes food to rot.
What is some background information on apples turning brown?

How does air dirt and oil effect photosynthesis?
air Moisturised the dirt in the ground then it turns ROM blue to brown
Why does olive brine turn brown after opening?

Why aromatic amines turns brown on exposure on air?
Aromatic amines can undergo oxidation reactions when exposed to air, leading to the formation of colored compounds. This brown coloration is due to the formation of various oxidation products resulting from the reaction of the aromatic amine with atmospheric oxygen. The presence of these colored compounds is often indicative of the degradation of the aromatic amine molecule.
What should you do if part of your sauerkraut you are making turns brown can you take the brown part out and proceed or should the whole jar be thrown out?
It usually means that the sauerkraut has oxidized,which is caused by contact with the air. This isn't exactly dangerous, so you can just discard the brown part. If the brown coloration is caused by exposure to copper, brass, or lead, then it is unsafe. If you are completely sure it is oxidation, then you can just throw the brown part out and continue.
What kinda of chemical change do you think occurs when a banaana peel turns brown in the open air?
Oxidation
What does a low-order explosive material resemble when exposed to air and sunlight?
These types of explosives resemble dark brown rocks after exposure to the elements, and they often begin to decompose after such exposure as well.
Why silver turns black on exposure to air?
Silver turns black on exposure to air due to a chemical reaction with sulfur compounds present in the air, forming silver sulfide. This process is known as tarnishing. Polishing the silver can remove the black tarnish and restore its shine.
