scienceQA-11419	multiple_choice	What do these two changes have in common? baking an apple pie rust forming on a metal gate	[ "Both are only physical changes.", "Both are chemical changes.", "Both are caused by heating.", "Both are caused by cooling." ]	B	Step 1: Think about each change. Baking an apple pie is a chemical change. The type of matter in the pie changes. The apples become soft, and the crust turns brown. 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. Baking is caused by heating. But rust forming on a metal gate is not. Both are caused by cooling. Neither change is caused by cooling.

What do these two changes have in common? baking an apple pie rust forming on a metal gate

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

B

Step 1: Think about each change. Baking an apple pie is a chemical change. The type of matter in the pie changes. The apples become soft, and the crust turns brown. 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. Baking is caused by heating. But rust forming on a metal gate is not. Both are caused by cooling. Neither change is caused by cooling.

Select the chemical formula for this molecule.

[ "HF", "HeF", "HF2O", "HF2" ]

A

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