KBr will undergo dissociation in solution while benzene will undergo solvation. True or False

False.

KBr will undergo dissociation in aqueous solution.

But benzene will not dissolve in water, so it will not be solvated.

How do you do this problem?
Svetradugi [14.3K]

Answer:

B

Explanation:

If the temperature of the water goes up, the reaction is exothermic (heat is being given away by the equation -- more precisely the reactants of the equation). Only A and B can be true. In order for the reaction to occur, the water has to absorb the heat. It's temperature goes up. Remember that minus sign. It is almost the key fact for this question.

The question is not as hard as it looks, but that is easy for me to say.

m = 100 g

c = 4.2 J/(g * oC)

deltaT = 21 - 20 degrees = 1 degree.

Heat = 100 * 4.2 * 1

Heat = 420 J

Heat = 420 * [1 kJ/1000 J]

Heat = -0.42 kJ

B

For the reaction NH4NO3 (s) → N2O (g) + 2H2O (l), you decompose 1 mole NH4NO3 and only get 0.75 moles of N2O. The percent yield
attashe74 [19]

Answer:

The answer to your question is False.

Explanation:

Data

1 mole of NH₄NO₃

0.75 moles of N₂O

Percent yield = 25%

Chemical reaction

               NH₄NO₃   ⇒   N₂O  +  2H₂O

Process

1.- Determine the theoretical yield

              1 mol NH₄NO₃ ------------- 1 mol of N₂O

2.- Calculate the percent yield

             Percent yield = Actual yield / Theoretical yield  x 100

-Substitution

              Percent yield = 0.75 / 1 x 100

-Simplification

              Percent yield = 0.75 x 100

-Result

              Percent yield = 75%

Conclusion

False, the actual percent yield is 75%

How is the Delta Hf related to the delta H of <br> a reaction?
artcher [175]

Answer:

n a chemical reaction, delta H represents the sum of the heats of formation, commonly measured in kilojoules per mol (kJ/mol), of the products minus the sum of those of the reactants. The letter H in this form is equal to a thermodynamic quantity called enthalpy, representing the total heat content of a system.
