Jet001 [13]
The request is characterized as knowing where things are and having the capacity to discover and utilize the things. 
In a compound procedure, there is more issue, more entropy when the particles 
1. warm up, increment in temperature. The atoms are more disorganized 
2. get stirred up and must be isolated with exertion. Bedlam. 
3. state changes, dissolves, vaporizes. The atoms are more turbulent 
4. respond to frame a pack of various particles. More disorder

Thich of the following is a chemical property2
Dimas [21]

Answer:

"Freezing point  and ability to react with oxygen" are chemical properties

Explanation:

The change of liquid into solid is the freezing point. The melting point is more than the freezing point in certain cases of mixtures for certain organic compounds like fats. As soon as the mixture freezes it becomes solid and which results in change in the composition from the liquid and solid in this way the it drastically reduces the freezing point. The melting point gets higher due to the pressure. This happens due to the release of heat of which results in the rise of temperature to the freezing point .Also the reaction of elements with oxygen which leads to formation of new substance is also an chemical property
