Problem 147 Hard Difficulty

Consider the decomposition of liquid hydrogen peroxide (H2O2) to form water and oxygen.
a. What is the heat of formation for hydrogen peroxide?
b. What is the heat of formation for liquid water?
c. What is the heat of formation for gaseous oxygen? Why?
d. Write the balanced chemical equations that correspond to the H values you looked up for parts a, b, and c.
e. Write the balanced chemical equation for the decomposition of hydrogen peroxide to form water and oxygen. (Write the equation such that the coefficient on oxygen is 1.)
f. What is the heat of reaction for the process in part e?
g. Draw a scale diagram of this reaction in which 1 cm = 100 kJ showing the relative energies of reactants (on the left), products (on the right), and the elements in their most stable states (in the middle). Label all the energies you know.

Answer

considering the decomposition off hydrogen peroxide as followed. Do you have? It's two or two. Give me to edge too. Less or two. The heat off Formacion off. The substance is defined us. And tell me change that takes place when one mole off compound is formed from its constituent elements in their standard state. The reaction off H 20 tow information is shown. US followed. It's too. Yes. 02 gives me h Oh, oh, Inch mathematically. The heat off formation off EJ toe is find using the full integration. So on, left inside will be born broken, right? And so it born formed. So we have. Don't wander off as 498 Hello, Jules or more. We have hydrogen bone breaking is equal. Do 436 Killer Jones. The born form will be to off, which gives me 928. Calo Jules on DDE. The born off oxygen to excision gives me 142 killer Jules, the heat off formation is calculated. Bye. Born broken. Subtracting the intel a p off born form giving us the heat off formation as negative. 136. Killer Jules for option B. The heat or formation off liquid Bordeaux is also calculated, which turns out to be negative. 243 Killer Jones For more yes, option C The heat or formation off oxygen gas excision Guests is Tzeitel because the standard elemental form off excision element Option D. The balance equation for the formation off hydrogen peroxide is also shown. It is, it's too plus or two gives me vegetal or two. The balanced equation for formation off water is given itch to bless. Half photo gives me its stool and ocean e the falling for the decomposition off hydrogen peroxide to form water along with oxygen gases. All social. So it is to edge too, too. Or do blessed Oh, sorry, resource in tow to its toe. Unless Books Ian the final hit off, the reaction for the creation can be presented on dhe. The change in mentality can be determined for the entire pee off the products minus the entirely be off the reactive, the changing and tell a P is negative 107 kilo jewels for more.
