Hi!! please help :( lots of points !
andreev551 [17]

Answer:

<u><em>Structure:</em></u>

<em>Differences-  </em>A polymer is a collection of a large number of molecules whereas a monomer is a single molecule.

A monomer is a single molecule, which has the ability to chemically bond with other monomers in a long chain. A polymer is a chain that is made when monomers bind with other monomers.

<em>Similarities-</em>  They are both molecules

<u><em>Properties:</em></u>

<em> Differences- </em>Monomers have polyfunctionality, which is the capacity to form chemical bonds to at least two other monomer molecules. Polymers are chemically unreactive, solids at room temperature, malleable, tough, and are electrical insulators.

<em>Similarities- </em>They both makeup larger forms of matter.

<u><em>Intermolecular Forces</em></u>

<em>Differences: </em>Polymers are held together by covalent bonds, hydrogen bonds, and dispersion bonds. Monomers are <u><em>only</em></u> held together by hydrogen bonds.

<em>Similarities: </em>They can both be bonded together by hydrogen bonds.

In the combustion of propanol, what is the molar ratio of propanol (ch3ch2ch2oh) to co2? combustion of propanol: 2ch3ch2ch2oh +
maksim [4K]
Propanol molecular formula is C₃H₇OH
the balanced reaction for combustion of propanol is as follows;
2C₃H₇OH + 9O₂ --> 6CO₂  + 8H₂O
Molar ratio of reactants to products can be found out by the stoichiometry.
By looking at the coefficients of reactants and products in the balanced reaction equation, molar ratio can determined.
Therefore the molar ratio of propanol to CO₂ is 2:6, simplified --> 1:3

A female bear leaves her bear cubs in their den to go out in search of food. She travels one mile in 30 minutes, heading east. S
Vinil7 [7]

Answer:

Points of acceleration:

1. When female bear goes quickly

2. After becoming tired, when she becomes slow

3. When she changes direction from east to north

4.When she slows down when she reaches the river bed

5. When she turns around

6.When she increases speed to travel southwest to return home

7. When she comes to a stop at home

Explanation:

1. When she is going quickly she is increasing her velocity thus positively accelerating

2. When she becomes slow, she is having negative acceleration.

3. When there is a change in direction of velocity there is an acceleration.

4. Again negative acceleration when she comes to a stop at the river bed

5. Turning around to the southwest direction requires acceleration

6. To increase the velocity to reach home, positive acceleration

7. To decrease the velocity to stop upon reaching home, negative acceleration
