The answer is A. Hydrogen bond

Molecules that have nonpolar covalent bonds donot form hydrogen bonds. Strenght. Hydrogen bonds are classified as weak bonds because they are easily and rapidly formed and broken under normal biological conditions.

Hope I helped :)

How does the kinetic energy of solids liquids and gases compare?
maksim [4K]
<h2> <em>QUESTION</em><em>:</em><em> </em><em>how does the kinetic energy of solids liquids and gases compare?</em></h2>

<h2> ANSWER:</h2><h3><em>Gases have the high kinetic energy because its particles are far apart from each other and have negligible fprce of attraction whereas liquids have high force of attraction as compared to gases so they have less kinetic energy then gases,and Solids have high force of attraction between its particles because of that its molecules are closely packed ,so solids do not have kinetic </em><em>energy.</em></h3><h2><em>HOPE</em><em> </em><em>IT </em><em>HELPS </em><em>YOU</em></h2>

Use kinetic molecular theory to explain why a gas takes the shape and volume of its container
Tamiku [17]

Answer:

Imo : Gas particles are in constant, random motion. The volume of gas particles is negligible in comparison to the volume of the container. There are no attractive forces between gas particles.

1. (8pt) Using dimensional analysis convert 600.0 calories into kilojoules
Ivanshal [37]

Answer:

1. 2.510kJ  

2. Q = 1.5 kJ

Explanation:

Hello there!

In this case, according to the given information for this calorimetry problem, we can proceed as follows:

1. Here, we consider the following equivalence statement for converting from calories to joules and from joules to kilojoules:

1cal=4.184J\\\\1kJ=1000J

Then, we perform the conversion as follows:

600.0cal*\frac{4.184J}{1cal}*\frac{1kJ}{1000J}=2.510kJ

2. Here, we use the general heat equation:

Q=mC(T_2-T_1)

And we plug in the given mass, specific heat and initial and final temperature to obtain:

Q=236g*0.24\frac{J}{g\°C} (34.9\°C-8.5\°C)\\\\Q=1495.3J*\frac{1kJ}{1000J} \\\\Q=1.5kJ

Regards!
