What else can I help you with?
If you put a banana in a cupboard for a week and it turns black does that mean it is a chemical reaction?
No, the banana turning black is not a chemical reaction in the traditional sense. It is a natural process called enzymatic browning, where enzymes in the banana react with oxygen in the air, causing the fruit to darken. The change in color is due to the breakdown of pigments in the banana, not a chemical reaction.
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!!

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 dissecting a banana a chemical reaction or a reversible change?
Dissecting a banana is a physical change, not a chemical reaction. It involves physically separating the banana into smaller pieces, but the chemical composition of the banana doesn't change. A reversible change would be when you freeze the banana slices and then thaw them, as this can be reversed.
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.
