Will you please check? Physical or chemical properties

1. bitter taste = physical taste 2. can neutralize a base= physical property 3. boiling point = physical property 4. reacts with a base to form water= physical
5. reacts with acid to form hydrogen = chemical property 6. solubility= physical 7. flammability =chemical 8. density = physical

physical:chemical::size: ________________________ flammability, taste, solubility, acid

To determine if a property is physical or chemical, we need to understand the difference between them. Physical properties are characteristics that can be observed or measured without changing the substance's chemical composition, while chemical properties describe how a substance undergoes chemical reactions and changes in its composition.

Now let's analyze each statement:

1. Bitter taste = physical taste
You determined this as a physical property. Taste is a sensory observation and, in this case, does not involve any chemical changes.

2. Can neutralize a base = physical property
You also classified this as a physical property. Neutralizing a base means it can counteract the basic properties without undergoing a chemical reaction.

3. Boiling point = physical property
You correctly identified this characteristic as a physical property. Boiling point refers to the temperature at which a substance changes from a liquid to a gas phase, without any chemical modifications.

4. Reacts with a base to form water = physical property
This statement is incorrect. Reacting with a base to form water is a chemical property. It describes the substance's ability to undergo a chemical reaction and produce a new substance (water) with different properties.

5. Reacts with an acid to form hydrogen = chemical property
You correctly classified this as a chemical property. The ability to react with an acid to produce hydrogen involves a chemical reaction and a change in composition.

6. Solubility = physical property
You correctly identified this characteristic as a physical property. Solubility refers to the ability of a substance to dissolve in a particular solvent, without any alteration in its chemical structure.

7. Flammability = chemical property
You correctly identified this as a chemical property. Flammability refers to a substance's ability to combust and react with oxygen, producing heat and light, therefore involving a chemical reaction.

8. Density = physical property
You correctly identified this characteristic as a physical property. Density is a measurement of the mass per unit volume of a substance, which does not involve any chemical changes.

Remember, it is important to consider the nature of the property in question to determine if it is physical or chemical.
