Q1. Compare the bonding and structure of the three compounds, poly(propene), propanol and silicon dioxide. Q2. Explain why the melting points of the three compounds differ from each other. poly(propene): 160 degrees propanol: -126 degrees silicon dioxide: 1600 degrees

The chemical compounds that were named included with the following characteristics:

Propene or also called Propylene, is an Alkene (this means that in its structure it has a double bond between two carbons) formed by 3 carbon atoms and 6 hydrogen atoms, its global formula is C3H6. It is a homolog of ethylene, it presents the double bond as a functional group.

The chemical compound propan-1-ol is a colorless alcohol, very miscible with water. It is required called propanol, n-propanol, propyl alcohol or alcohol

Silicon oxide (IV) or silicon dioxide (SiO2) is a compound of silicon and oxygen, called silica, its structure is crystalline, this means that it is a simple view of the human eye and it is opaque. a three-dimensional red form quartz and all its varieties and is widely used in dentistry.

These compounds have different temperatures because they have different bonds, alkene has double bonds, another has an alchol group that is propanolol and lastly silicon dioxide, which is a highly resistant dioxide in its structure.

Explanation:

The melting points or temperatures are different between chemical compounds, since they vary if they have complex unions, or some stronger than others, or also because they have oxygen groups such as alcohol or ketone.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
