Question
- put a checkmark next to the description if its a chemical property or physical property.
| chemical property | physical property | |
|---|---|---|
| toxicity – a measure of the damage a substance can cause to an organism | ||
| hydrolysis – the measure of chemical breakdown due to a reaction with water | ||
| color – the color an object has | ||
| flammability – how easily a substance burns | ||
| mass – the measure of particles or stuff in an object |
Response
To solve this, we recall:
- Physical properties can be observed/measured without changing the substance’s chemical identity (e.g., volume, color, mass).
- Chemical properties describe a substance’s ability to undergo chemical changes (e.g., toxicity, hydrolysis, flammability).
1. Volume – the measure of space an object takes up
- Observed without chemical change.
- Check: $\boldsymbol{\text{Physical property}}$
2. Toxicity – a measure of the damage a substance can cause to an organism
- Relates to chemical reactions (e.g., poisoning).
- Check: $\boldsymbol{\text{Chemical property}}$
3. Hydrolysis – the measure of chemical breakdown due to a reaction with water
- Involves a chemical reaction (breakdown).
- Check: $\boldsymbol{\text{Chemical property}}$
4. Color – the color an object has
- Observed without chemical change.
- Check: $\boldsymbol{\text{Physical property}}$
5. Flammability – how easily a substance burns
- Involves combustion (a chemical reaction).
- Check: $\boldsymbol{\text{Chemical property}}$
6. Mass – the measure of particles or “stuff” in an object
- Measured without chemical change.
- Check: $\boldsymbol{\text{Physical property}}$
Final Table (with checks):
| Description | Chemical property | Physical property |
|---|---|---|
| toxicity – a measure of the damage a substance can cause to an organism | $\boldsymbol{\checkmark}$ | $\square$ |
| hydrolysis – the measure of chemical breakdown due to a reaction with water | $\boldsymbol{\checkmark}$ | $\square$ |
| color – the color an object has | $\square$ | $\boldsymbol{\checkmark}$ |
| flammability – how easily a substance burns | $\boldsymbol{\checkmark}$ | $\square$ |
| mass – the measure of particles or “stuff” in an object | $\square$ | $\boldsymbol{\checkmark}$ |
