Chemical change
does not matter once the Powder has starch it turns black and the powder can be any color
clouds get black by the smoke and when its going to rain the water from the sea turns in gas and then goes on clouds.
I did this lab experiment in my biology class. When Lugol's indicator is added to glucose, it turns to a dark green colour for starch it turns black and for surcose it turns yellow.
Yea
starch
it stanks
it turns black because air is around it when u open a banana use airtight Ziploc i read this in a science from scientist
Because they rot quicker. There's a greater surface area , both the inside and the outside , that is exposed to the air .
potassium in the banana reacts to water and melts the banana
If neither has been peeled/bitten, the banana. If they've been peeled/bitten, the apple.
BlackAns2:It is very unlikely that a ripe banana will have enough starch to turn iodine black. When iodine turns black, it is a positive test for the presence of starch.
yes, if it turns into a different colour than it is a chemical reaction. hope that helps
Well just place your left hand shove it down the toilet and grab for the banana then if its not peeled eat it
To start, make a small cut near one of the tips, then peel off a strip of the skin, then peel off more strips until it is all peeled (generally a banana can be peeled with 4 or 5 strips).
Yes
It is rotten and mushy and should not be eaten like a ripe banana. However, it is good for making banana bread.
This Banana turns blue!
