Chemical Properties and Chemical Changes
Chemical properties are those that can only be measured or experienced by altering the identity of matter.
Chemical properties include (but are not limited to)
- ability to burn
- ability to react with acids
- elemental composition (what it's made of on the smallest scale)
To understand this, let's look at the first property - abilty to burn. We know that paper burns. However, this can only be seen by lighting the paper on fire, resulting in the loss of the paper and the creation of water, carbon dioxide and ash.
Changes of this nature, those that demonstrate chemical properties, are called chemical changes.
