Select the chemical formula for this molecule.
[ "C2I4", "CI4", "C4I", "CI" ]
B
C is the symbol for carbon. According to the legend, carbon atoms are shown in dark gray. I is the symbol for iodine. According to the legend, iodine atoms are shown in dark purple. This ball-and-stick model shows a molecule with one carbon atom and four iodine atoms. The chemical formula will contain the symbols C and I. There is one carbon atom, so C will not have a subscript. There are four iodine atoms, so I will have a subscript of 4. The correct formula is CI4. The diagram below shows how each part of the chemical formula matches with each part of the model above.

A
Step 1: Think about each change. A slice of banana turning brown is a chemical change. The part of the banana in contact with the air reacts with oxygen and turns into a different type of matter. Grilling a hamburger is a chemical change. Heat from the grill causes the matter in the meat to change. Cooked meat and raw meat are different types of matter. Step 2: Look at each answer choice. Both are only physical changes. Both changes are chemical changes. They are not physical changes. Both are chemical changes. Both changes are chemical changes. The type of matter before and after each change is different. Both are caused by heating. Cooking a hamburger is caused by heating. But a slice of banana turning brown is not. Both are caused by cooling. Neither change is caused by cooling.
