| Question | Answer |
|---|---|
| A [...] property is a characteristic of a substance that you can see without changing the identity of the substance (by chemically reacting it with something). | A physical property is a characteristic of a substance that you can see without changing the identity of the substance (by chemically reacting it with something). |
| A [...] property is how something chemically reacts with other substances. | A chemical property is how something chemically reacts with other substances. |
| One important physical property is denity (D), the ratio of [...] (m) to volume (V ). | One important physical property is density (D), the ratio of mass (m) to volume (V ). |
| The formula for density is D = [...], where m is measured in grams (g) and V is measured in milliliters (mL) or cubic centimeters (cm^3). | The formula for density is D = m/V, where m is measured in grams (g) and V is measured in milliliters (mL) or cubic centimeters (cm3). |
| The density of water is [...] g/ml | The density of water is 1 g/ml |
| [...] changes do not change the composition of matter. | Physical changes do not change the composition of matter. |
| Chemical properties must be observed by detecting chemical [...]. | Chemical properties must be observed by detecting chemical changes (or reactions). |
| A [...] change is one where a substance changes its identity; becoming one or more different substances. | A chemical change is one where a substance changes its identity; becoming one or more different substances. |
| [...] changes occur when substances interact with each other. | Chemical changes occur when substances interact with each other. |
| Color change is usually a sign of a [...] change (a new substance with a different color has been produced) | Color change is usually a sign of a chemical change (a new substance with a different color has been produced) |
| If gas is given off without boiling, that’s usually a sign of a [...] change. | If gas is given off without boiling, that’s usually a sign of a chemical change. |
| If a substance changes temperature on its own (you didn’t stick it in the microwave or something), that’s usually a sign of a [...] change. | If a substance changes temperature on its own (you didn’t stick it in the microwave or something), that’s usually a sign of a chemical change. |
| If you mix two liquids together and a solid forms and sinks to the bottom, that’s usually a sign of a [...] change. | If you mix two liquids together and a solid forms and sinks to the bottom, that’s usually a sign of a chemical change. |
| Precipitation is when water comes out of the mixture we call the sky. In chemistry, a [...] is likewise, any substance that comes out of a mixture. | Precipitation is when water comes out of the mixture we call the sky. In chemistry, a precipitate is likewise, any substance that comes out of a mixture. |
| A precipitate is usually new substance that has been formed through a [...] change (a new substance that does not dissolve in the liquid). | A precipitate is usually new substance that has been formed through a chemical change (a new substance that does not dissolve in the liquid). |
