What else can I help you with?
If you put a banana in a warm cupboard for a week will it turn black and will it be chemical or physical change?
If you put a banana in a warm cupboard for a week, the likelyhood of it turning black is very high. This is a chemical change, as it is caused by the internal decomposition (breaking down) of the sugars contained by the fruit. Please note for future that a physical change is in nearly always a change in state, including disolvsion in a solvent.
Is bananas turning black a chemical or physical reaction?
The answer is actually microorganisms.In school we did a topic about it so it will be chemicals. Aleema hope it helpedxx
Is it a chemical reaction if you but copper in a fire and it turns black?
yes it is a chemical reaction because the change involved heat and all chemical reactions involve heat and a difference in the appearence of the substance which has recieved heat is noticed
How do new substances form?
New substances can form through chemical reactions, where atoms from different elements rearrange to create new compounds with unique properties. These reactions can involve the breaking and forming of chemical bonds. Additionally, changes in temperature, pressure, or the presence of catalysts can also influence the formation of new substances.
What change in color is observed when silver chloride is left exposed to sunlight. What type of chemical reaction is this?
This is a photochemical reaction of decomposition: silver (black) is released.
Is bananas turning black if you leave them in a warm cupboard for a week a chemical reaction and why?
Yes, it is a chemical reaction, because the colour of the banana has changed, which shows that a chemical reaction has taken place. Also, if the banana has gone black and turned bad, you can't change it back to it's original form, which proves that it is a chemical reaction and not a physical reaction. Remember - A chemical reaction has definitely taken place if : It's colour has changed A gas is given off There are energy changes Or, it can't be changed back to what it used to be! :) Hope this helps!!
Is banana's turning black a chemical reaction?
No, some people say that but it is not true!
When you leave a banana in a cuboard it turns black is this a physical or chemical reaction and why?
It's a chemical reaction, as a banana is a fruit it leaves some micro particles into the air for growing faster. When it is on a tree this particles get mixed with air & couldn't help it so much for growing, but when it is in a packed cupboard there is not much space for the particles to roam, as the particles are nearer to banana, it starts to act upon banana & the starts growing faster & the banana gets ready, but after being ready also it stills continue to absorb micro particles & thus starts becoming black.

When a peeled banana turns black is a?
normal process called enzymatic browning, where enzymes within the fruit cause oxidation when exposed to air. This oxidation leads to the blackening of the banana's peel. It is not harmful to eat the banana but may affect its taste and appearance.

Is it ok to eat a black banana?
Black banana's are safe to eat. When they darken their sugars become concentrated and they become very sweet. This banana is very good in making banana pound cakes, loafs, and muffins. When I buy banana's I wait until they become totally blackened so that I can use them for baking a great banana treat!
