When two different substances combine by making chemical bonds, the result is another chemical compound.
It's certainly easier than making a jelly using non-chemical substances. You're going to need to be a lot more specific if you want sensible answers.
making lemonade is a physical change i believe
They are similar because you are producing a chemical change in both, making new substances.
Making lemonade is a physical change because the powder and water do not combine chemically. It becomes an aqueous mixture.
Boiling water does not change the chemical make up of water, it just changes the state of the matter from liquid to gas. Rust is caused by a chemical reaction to the metal making an oxide which is a different compound.
After making sure they are not dangerous, by smelling them.
It's Chemical, Because if you combine cheese from milk it will Change it appearance.
That's not really a answerable question because when atoms combine with other molecules you are just making bigger molecules or a smaller ones. You're not making any specific substances.

Chemical reactions are based on electrons transfer or sharing.

If you mean Autotroph, it is an organism capable of making its own food from inorganic substances using light or chemical energy

lol i re-learned this 2day its a chemical change because it turns into something diffrent, (the texture, and temp it must be) and you cannot get the cream back. Hope i helped :)
As long as you are not adding or subtracting substances, the shape you put the metal in is purely a physical change.
