4. If the Law of Conservation of Energy states that energy is neither be created nor
destroyed, but can only be transferred or changed from one form to another, why do
scientists worry about running out of energy in the future?
A 15.00 g sample of a solid substance is placed in 100.0 g of water at 25°C, and all of the solid dissolves. Then another 2.00 g of the substance is added, and all of it dissolves. A final 2.00 g is added, and none of it dissolves.
•Is the first solution saturated, unsaturated, or supersaturated?
•Is the second solution saturated, unsaturated, or supersaturated?
•What can you tell about the final solution that is in contact with the solid?
Use the information below to answer questions 1- 3.
PCI,(g) 2 PCI;(g) + Cl2(8)
PCI,(g) decomposes into PCI,(g) and Cl,(8)
according to the equation above. A pure sample of
PCI,(g) is placed in a rigid, evacuated 1.00 L
container. The initial pressure of the PCI5(g) is
1.00 atm. The temperature is held constant until
the PCI,(g) reaches equilibrium with its
decomposition products. The figures below
show the initial and equilibrium conditions of the
system.
PCI5
Potal = 1.00 atm
PCI5, PCI3, and CI,
Prstal = 1.40 atm
Figure 1: Initial
Figure 2: Equilibrium
As the reaction progresses toward equilibrium, the
rate of the forward reaction
(A) increases until it becomes the same as the
reverse reaction rate at equilibrium
(B) stays constant before and after equilibrium is
reached
(C) decreases to become a constant nonzero rate
at equilibrium
(D) decreases to become zero at equilibrium
If the decomposition reaction were to go to
completion, the total pressure in the container
would be
(A) 1.4…

This friend tells you that this can’t be true because exothermic implies “hot,” and ice is cold. Is the process of water freezing exothermic? If so, explain this process so your friend can understand it. If not, explain why not.arrow_forwardEnthalpy a A 100.-g sample of water is placed in an insulated container and allowed to come to room temperature at 21C. To heat the water sample to 41C, how much heat must you add to it? b Consider the hypothetical reaction,2X(aq)+Y(l)X2Y(aq)being run in an insulated container that contains 100. g of solution. If the temperature of the solution changes from 21C to 31C, how much heat does the chemical reaction produce? How does this answer compare with that in part a? (You can assume that this solution is so dilute that it has the same heat capacity as pure water.) c If you wanted the temperature of 100. g of this solution to increase from 21C to 51C, how much heat would you have to add to it? (Try to answer this question without using a formula.) d If you had added 0.02 mol of X and 0.01 mol of Y to form the solution in part b, how many moles of X and Y would you need to bring about the temperature change described in part c. e Judging on the basis of your answers so far, what is the enthalpy of the reaction 2X(aq) + Y(l) X2Y(aq)?arrow_forward
