Answer:
C) Iron Combines readily with oxygen
Explanation:
When Iron combines readily with oxygen well... it rusts making it a new substance
Option A. Smaller atoms and stronger bonds.
Smaller the size of the atoms, less will be the distance between positive charge nucleus of one atom and electrons (negative charge) of other atom. This results in strong interaction between them.
Also, stronger bonds are difficult to break, making the minerals harder. Thus, small atoms and strong bonds in minerals makes then harder than the minerals with weak bonds or larger atoms.
The answer is Electrolysis I think based off of the definitions.
Amylase is the enzyme found in saliva an starts to digest food from in the mouth. Starch is a polysaccharide found in foods such as bread, yam, potatoes. This molecule is the carbohydrate component of foods and is the main source of energy as food. At the moloecular level, the enzyme amylase breaks the bond that forms maltose into two individual glucose molecules.

The atoms of a chemical element can exist in different types. These are called isotopes. They have the same number of protons (and electrons), but different numbers of neutrons. Different isotopes of the same element have different masses.</span>
