Select the chemical formula for this molecule.

[ "HI2", "HI", "HeI", "He2I2" ]

B

H is the symbol for hydrogen. I is the symbol for iodine. This ball-and-stick model shows a molecule with one hydrogen atom and one iodine atom. The chemical formula will contain the symbols H and I. There is one hydrogen atom, so H will not have a subscript. There is one iodine atom, so I will not have a subscript. The correct formula is HI. The diagram below shows how each part of the chemical formula matches with each part of the model above.

What do these two changes have in common? milk going sour rust forming on a metal gate

[ "Both are only physical changes.", "Both are caused by heating.", "Both are chemical changes.", "Both are caused by cooling." ]

C

Step 1: Think about each change. Milk going sour is a chemical change. The type of matter in the milk slowly changes. The new matter that is formed gives the milk its sour taste. Rust forming on a metal gate is a chemical change. As the gate rusts, the metal turns into a different type of matter called rust. Rust is reddish-brown and falls apart easily. 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. Neither change is caused by heating. Both are caused by cooling. Neither change is caused by cooling.

What do these two changes have in common? molding clay into the shape of a pot breaking a stick in half

[ "Both are caused by heating.", "Both are chemical changes.", "Both are caused by cooling.", "Both are only physical changes." ]

D

Step 1: Think about each change. Molding clay into the shape of a pot is a physical change. The clay gets a different shape. But it is made of the same type of matter. Breaking a stick in half is a physical change. The stick gets broken into two pieces. But the pieces are still made of the same type of matter as the original stick. Step 2: Look at each answer choice. Both are only physical changes. Both changes are physical changes. No new matter is created. Both are chemical changes. Both changes are physical changes. They are not chemical changes. Both are caused by heating. Neither change is caused by heating. Both are caused by cooling. Neither change is caused by cooling.
