Your aftershave has turned cloudy because the ingredients have separated. This means that it was exposed to light or a change in temperature that caused a chemical reaction.
physical change, because the frozen rain can be turned back into rain (or water if you want to be exact) But a good example of a chemical reaction would be, you have the ingredients for a cake, you take those ingredients, mix and bake them, that would be a chemical reaction because it cannot be turned back into a cake
A chemical change is a resultant change of a combination of a couple different substances that become a new substance. A sentence with this is: "Its particles changed due to it undergoing a chemical change."
Sun spots of course
Chemical change.

This is a chemical change, like any other burning reaction: magnesium is turned into magnesium oxide by burning reaction with oxygen (from air). 2Mg + O2 --> 2MgO

Of course you can. Any number can be turned into a percent.
of course not! she is a girl vampire that's all

The Titanic did not really change course after its impact with the iceberg. The ship turned slightly to avoid hitting the iceberg more than it had, but it was still headed towards America.
A chemical reaction is a reaction in which a substance is turned into another completely different substance
Ty should conclude that a chemical reaction has taken place. Change of color is a typical sign that a chemical reaction has occurred.
Yes it is, as the browning of the bread when you toast it, is a reaction between the reducing sugar and amino acids. The reaction is called Maillard reaction. In simpler words, the bread is being "burned" which is a chemical change as it cannot be reversed. You can't get back the same soft,fluffy, white bread after you toast it.

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!!
