Is a molecule a substance that a chemical reaction can't break down?
Yes, a molecule is the smallest unit of a substance that retains all of the chemical properties of that substance. In a chemical reaction, molecules may rearrange or combine with other molecules, but they themselves are not broken down into smaller parts.
What is a chemical change in which a larger substance is broken down into smaller substances?
Decomposition reactions involve the breakdown of one larger molecule into several smaller molecules.
What is the smallest quantity that a chemical compound can be divided into and still maintain its chemical properties?
The general answer would be molecule however some molecules prefer to exists as paired molecules and subdividing them would alter some of its chemical properties: a good example of this would be the sugars.
What is a mixture in which a substance does not dissolve but does not break into smaller pieces?
a molecule
Enzymes split large molecules into two or more smaller molecules by adding water through which type of reaction?
Hydrolysis is the reaction that stems from the breakdown of large molecules by the enzymatic addition of water. Hydrolysis is step leading to the degradation of the substance. It is a chemical reaction in which a molecule of water is added to a substance. At times water and the substance will split and one part of the parent molecule will receive one hydrogen ion.
A number that is lower and smaller than the letter symbols in a chemical formula that shows how how atoms of a substance are in a molecule is called?
coefficent
A number that is lower and smaller than the letter symbols in a chemical formula that shows how many atoms of a substance are in a molecule is called?
coefficent

Whats the smallest unit of a substance that behaves like a substance?
A molecule of the substance. An atom of an element may exhibit different characteristics when it is bound to other atoms of the same element. Examples are common oxygen (O2) and ozone (O3) with altered chemical properties. Or carbon as graphite (hexagonal lattice) and diamond (tetrahedral lattice), which demonstrate very different physical properties.

What is the name given to smaller particles which have joined to form a chlorine molecule?
The smaller particles that join to form a chlorine molecule are called chlorine atoms. Two chlorine atoms bond together through a covalent bond to form a chlorine molecule, which has the chemical formula Cl2.
Is iodine larger than glucose?
iodine cells are smaller then glucose ------- I would take exception to the first answer. Iodine is clearly smaller because it exists as a diatomic molecule I2 while glucose is a molecule of 24 atoms, having the chemical formula C6H12O6.

Subscripts in a molecular formula represent the number of atoms of an element in a molecule?
That's right. When you have a chemical formula, such as SO4, the formula for Sulfate, the subscript means that there are four Oxygen atoms for every one Sulfur atom. Also, when you have really big molecules that are made up of several smaller molecules in them, such as Iron Sulfate, the subscript goes just outside of parenthesis surrounding the smaller molecule's own formula, like this: Fe2(SO4)3
What happens when a clear substnace undergoes a chemical change?
It is no longer that same substance. A chemical changes the identity of the substance. Individual atoms cannot be broken down into smaller parts by normal physical or chemical change.
