What kind of change such as a change of state the substance of the whole changes but its underlying structure remains the same?
In changes in which the molecular structure of a substance remains constant, such as changes of state, we often refer to these changes as Physical Changes. If the molecular structure is altered it would be a Chemical Change.
What is the shape of an amorphous substance?
an amorphous substance is something that has a random molecular formation in it's natural form (when solidified). the opposite would be semi-cristaline which has random molecular structure when heated but returns to an organised unifom state when solidified. example. certain polymers
What is the smallest particle of a substance that has all the properties of that substance?
For an element, it would be an atom. For a molecular substance, it would be a molecule. If it is an ionic compound, it would be a formula unit.

Can a soluble substance become in soluble?
If there is no reaction occuring to change the molecular structure of the substance, you have to look at the ionic product of the substance. When the ionic product is more than the Ksp of the substance, there would be precipitation of the substance
How many grams of the substance in the molecule C2O2H4 would be equal to 1 mol of the substance?
The mass in grams of a substance that equals one mole of that substance is the molecular weight of the substance, which can be found by adding the atomic weights of all the atoms in the molecule. For C2O2H4, the molecular weight would be (12 x 2) + (16 x 2) + (1 x 4) = 60 g/mol.
Is formula C60 a simple molecular substance or a giant covalent structure?
That's a very good question and there are arguments for both. I would class it more as a simple molecular substance because a sample will contain many separate molecules, with forces other than covalent bonds between them. A giant covalent structure like diamond is wholly held together by covalent bonds.
What is the molecular formula of a substance that has an empirical formula of C2H5 and a molecular mass of 58 grams per mole?
If C2H5 was the molecular formula its molecular mass would be 29 ( 12 x 2 + 5 x 1) However, 29 x 2 = 58 the actual molecular mass. So we double up the atoms in C2H5 to C4H10 . C4H10 is the molecular formula.
A substance has a melting point of 14c and a boiling point of 78c in what state is the substance at 78c?
The substance would be in a liquid and gas state, this would be due to vaporization that is happening during boiling.
