Which of the following compounds exhibit hydrogen bonding?
hodyreva [135]

Answer:

a,b,e,f,g

Explanation:

Hydrogen bonding is an intermolecular force of attraction between two molecules. It is a special type of dipole-dipole attraction.

In hydrogen bonding, the hydrogen on one molecule binds with an electronegative atom on another molecule usually oxygen, nitrogen and fluorine.

The simple electrostatic attraction leads to strong intermolecular interaction between two molecules.

 For the formation of hydrogen bond, a hydrogen atom must be bonded to more electronegative specie usually N, O and F

  In H₂O and H₂O₂ ;   hydrogen bonds with Oxygen

       CH₃NH₂; hydrogen is attached to nitrogen

       HF; hydrogen is attached to fluorine

        CH₃OH; hydrogen is attached to oxygen

You have 17 liters of gas at STP. If the temperature rises to 94C and while the volume decreases to 12 liters, what will the ne
fenix001 [56]

Answer:

P_2=1.90atm

Explanation:

Hello!

In this case, according to the ideal gas equation ratio for two states:

\frac{P_1V_1}{P_2V_2} =\frac{n_1RT_1}{n_2RT_2}

Whereas both n and R are cancelled out as they don't change, we obtain:

\frac{P_1V_1}{P_2V_2} =\frac{T_1}{T_2}

Thus, by solving for the final pressure, we obtain:

\frac{P_2V_2}{P_1V_1} =\frac{T_2}{T_1}\\\\P_2=\frac{T_2P_1V_1}{V_2T_1}

Now, since initial conditions are 1.00 atm, 273.15 K and 17 L and final temperature and volume are 94 + 273 = 367 K and 12 L respectively, the resulting pressure turns out to be:

P_2=\frac{367K*1.00atm*17L}{12L*273.15K}\\\\P_2=1.90atm

Best regards!

2. Work is done only when an object.<br> in the<br> of the force<br> that is being applied.
sp2606 [1]

Answer:

Whenever a force is applied to an object, causing the object to move, work is done by the force. ... Work can be either positive or negative: if the force has a component in the same direction as the displacement of the object, the force is doing positive work

Balance the equation and write the reaction-quotient expression, qc. u(s) + f2(g) ----&gt; uf6(g)
Alona [7]
The equation presented above is that of uranium reacting with fluorine forming uranium fluoride. 

The chemical reaction can be balanced by carefully studying the equation and balancing the number of atoms of each of the element in both sides of the chemical reaction. That is,
 
                  <em>         U(s) + 3F₂(g) --> UF₆(g)</em>
