Sugar is caramelized by heating (together with some proteinous material) giving taste and color change. Since this can NOT be undone (or reverted back to original state) by cooling or other simple physical processes, it is to be chemical.
It changes the sugar's color
It changes the sugar's color
Chemical change. References: Intro to Matter book.
You know a chemical change happened if: -A change in color -Formation of a precipate (a solid) -Formation of a gas
No, it is chemical reaction because it is producing a new substance. In the presence of heat sugar breaks down into carbon and water: C(12)H(22)O(11) [Scientific Formula for Sugar] ----> 12C+11H(2)O [New substance formed]
It changes the sugar's color
It changes the sugar's color
It changes the sugar's color
because the state changes from a liquid to a solid
It is a chemical change because it can not be reversed
because the sugar stays in a chain for the longest time before it dissolves you can also evaporate the water and find that the sugar is at the bottom, which makes it physical
Chemical change. References: Intro to Matter book.
Can you reverse the change?
Actually breaking a dinner plate is not a chemical change. A chemical change is like putting sugar into a hot cup of water or tea.
Its a chemical change because its changing what it is (from dough to bread)
Does anyone know
well you know its not a chemical change when you see the salt dissolving because if your were to put something else like sugar then it would be a chemical change because the sugar would just float right to the bottom and stay there but salt would go around in the water and start dissolving.
