Why does apply slice get brown color if kept in air for long time?
Yes, an apple slice that has been exposed to air can turn brown after a short period of time. If you need to keep the slices from turning, you can coat them with lemon juice or even lemon lime soda.
What element is a brown solid?
Iodine is a grey solid element that forms a purple gas on heating. :)
When sugar is exposed to dry heat what substance is form?
When sugar is exposed to dry heat, it caramelizes and forms a brown, sweet, and nutty substance called caramel.
How can sulfites stain clothing?
Sulfites can stain clothing by reacting with moisture in the air to form sulfur dioxide, which then oxidizes to create sulfurous acid. This acid can cause yellow or brown stains on fabrics when it comes into contact with them. The stains may be more noticeable when the clothing is exposed to heat or sunlight.
Is a brown apple a chemical change?
An apple turning brown is both a chemical and a physical change. Physically it changes appearance by turning brown. Chemically it oxidizes when the air comes in contact with the enzymes and chemicals in the fruit.
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 is an hypothesis for cutting an apple?
Hypothesis 1: When you disturb the skin of an apple by cutting the apple into half, the exposed area will turn brown due to exposure to air.Hypothesis 2: If you snugly wrap or cover the exposed area of an apple after cutting it (disturbing the skin), you can slow down how fast the inside turns brown. Hypothesis 3: If you remove all of the skin of an apple and let it sit in the air, the outside will turn brown but the inside will not turn brown at the same rate. Hypothesis 4: If you remove all the skin of an apple AND slice the whole apple into pieces, all sides exposed to air will turn brown; if some slices are thicker, the inside will turn brown more slowly than the exposed outside areas.
How do you speed the browning of an apple?
leave it out exposed to the air, some apples dont brown, pick one that does brown easily
Why should apple not be peeled?
An apple should not be peeled because it will turn brown when the flesh is exposed to the air this can be prevented with citric acid (lemon juice)
Are Sliced apples turning brown an example of chemical or physical property?
Sliced apples turning brown is an example of a chemical property, specifically oxidation. When the apple cells are exposed to oxygen, enzymes in the apple catalyze a reaction that changes the chemical composition of the apple's surface, causing it to turn brown.
Why does lime juice keep an apple from turning brown?
There is a high amount of acid in lime juice and the part of the apple that makes it turn brown(enzyme) when exposed to oxygen, has an edible effect on the enzyme to protect it from browning
What colour are apple seeds?

Why does apply slice get brown color if kept in air for long time?
Yes, an apple slice that has been exposed to air can turn brown after a short period of time. If you need to keep the slices from turning, you can coat them with lemon juice or even lemon lime soda.
What won't turn the apple brown?
I assume you are asking how to prevent a cut apple from oxidizing, or turning brown from contact with the air. Firstly, don't cut it before you need it...the longer it is exposed, the more chance for oxidization. Secondly, you can coat the exposed apple surfaces with lemon juice. Place the cut pieces in a Ziplock bag, add lemon juice, and shake gently to coat. The juice will inhibit oxidization. Thirdly, keep any cut apple pieces in an air-tight container to limit their exposure.
Does an apple skin protect the apple from chemical changes?
Not in general. It does protect the flesh of the apple from certain specific chemical changes (such as oxidation) to some extent, by keeping the oxygen away from the flesh. This is why an apple rapidly turns brown when you cut it: the previously protected flesh is now exposed to oxygen in the air.
What element is a brown solid?
Iodine is a grey solid element that forms a purple gas on heating. :)
An apple turning brown after being cut is an example of what chemisttry change?
The browning of an apple after being cut is an example of a chemical change called oxidation. When the apple's flesh is exposed to air, enzymes in the apple react with oxygen causing a chemical reaction that changes the color of the apple.
