Are the clues that indicate a chemical change always reliable?
Some indicators of a chemical reaction are:- change of color- change of odor- release of a gas- change of the temperature- change of the viscosity- formation of a precipitate- change of general appearance- possible explosion - possible chemiluminescence - formation of new compounds

No if you use your senses it is a physical change
What chemical change use conditions necessary for chemical changes in sugar?
Orange.
What methods do scientist use to determine if it is a physical or chemical change?
For a chemical change they analyze the new substances to prove there has been a change in the chemical composition. I am not sure about physical though.

it is chemical property. they use the word decomposition immaterially shows changein chemical composition.hence chemical change.

Why must you use chemical tests to reveal the presence of molecules?
Molecules are chemicals. A particular chemical posses a characteristic feature of forming an unique product when it undergoes chemical reaction along with another chemical. So to identify the chemical "A", one may use chemical "B" or "X" to react with chemial "A" to identify the formation of a product "AB" or "AX". This may many times evident by changes in color.

Difference between physical and chemical changes?
A chemical change results in the formation of a new substance. Example: igniting hydrogen in oxygen produces water. You can use these clues to determine a chemical change has occured: a colour change, a change in temperature, light and sound,bubbles beginning to form, solid/ semi solid precipitation form, and difficult to reverse it. A physical change is just a change of state or form eg melting ice or grinding salt. physical change can be the bending, cutting ,breaking, dissolving a substance in water (H2o)
