What do these two changes have in common? adding dish soap to water in a sink shaking up salad dressing

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

C

Step 1: Think about each change. Adding dish soap to water in a sink is a physical change. Bubbles may appear if air gets trapped in the soapy water, but a different type of matter does not form. Shaking up salad dressing is a physical change. The different parts mix together, but they are still made of the same type of matter. 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.

Select the chemical formula for this molecule.

[ "CH4", "CH", "ClH4", "H" ]

A

C is the symbol for carbon. H is the symbol for hydrogen. This ball-and-stick model shows a molecule with one carbon atom and four hydrogen atoms. The chemical formula will contain the symbols C and H. There is one carbon atom, so C will not have a subscript. There are four hydrogen atoms, so H will have a subscript of 4. The correct formula is CH4. The diagram below shows how each part of the chemical formula matches with each part of the model above.
