Calculate the enthalpy of formation for
sulfur dioxide, $\mathrm{SO}_{2},$ from its elements, sulfur
and oxygen. Use the balanced chemical
equation and the following information.
\begin{equation}
\begin{array}{c}{\mathrm{S}(s)+\frac{3}{2} \mathrm{O}_{2}(g) \rightarrow \mathrm{SO}_{3}(g) \quad \Delta H=-395.8 \mathrm{kJ} / \mathrm{mol}} \\ {2 \mathrm{SO}_{2}(g)+\mathrm{O}_{2}(g) \rightarrow 2 \mathrm{SO}_{3}(g) \quad \Delta H=-198.2 \mathrm{kJ} / \mathrm{mol}}\end{array}
\end{equation}

Were given a value for the delta H of formation at standard conditions for sulphur dioxide from its elements sulfur and oxygen. We can write out the chemical reaction for this formation has shown here where one sulfur +102 forms sulfur dioxide. I we want to determine how much energy is given off and we know that energy is released. Since this value is negative, Meaning this is an exo thermic reaction. We want to determine how much is released. Fourth, producing 30 grams of sulfur dioxide were given that value of 30 grams of eso to And we first want to convert this value and two moles because this reaction corresponds to the production formation of one mole of eso to and when we when we produce a single mole of that, this is how much energy is released. So we need to determine how many moles of S 02 is corresponds to producing 30 grams of eso to, and then we need to multiply it by the well to each of formacion value in order to cancel out the moles and determine the total amount of energy released so we can look up the molar mass of eso to using a periodic table. It's either there are 64.7 grams per mole of eso to, and that comes out to about zero 0.468 moles of eso to. So now we multiply that with the Delta H affirmation for a single mole of eso to to get the total amount of energy released. So that's zero point 468 moles Times negative 296 0.8 Killer jewels pull me so we cancel off moles in our final answer for the amount of energy released from the production of 30 grams of sulfur dioxide is negative 100 39 killing joules of energy.

Mm. Okay, so we have the thermo chemical equation gives us the entropy for every two moles of hydrogen sulfide. It's negative 1,036 killer jewels. Very yeah, two moles. So we need to convert moles to grams to figure out the killer jewels for a certain number of grants. So we know that there are 98.08 g. Yeah. Oops. I always do this. one mole of H two s is 98.08 g. That way, the most cancels out. And this will give you kill a jobs program. So then if you multiply by the number of g, which is 27.4, you'll get the killer jewels associated with that mess. Mhm grams will cancel with crabs. Okay, So 1036 divided by two divided by 90 a point oh nine. And then times 27 0.4 Gives you negative 100 44 .7 Killer Jewels.

So are balanced equation tells us We get 1,036 killed Jules released For every two moles Of our H two s. So that just comes from our balanced equation. So we're gonna start with 28,5g or if our age to us. So let's go ahead and change grams to moles, and one mole is 34 .09 g. And then we can change moles of age to us. It's a killer jewels. And we just said for every two malls negative 10 36 killer jewels, so we should give off 433 kill the jewels. And this is per 28 .5 g of our age to us.

For this problem. We're going to be looking at combining to chemical equations in order to get Ananth api change for a related transformation. So we're given to chemical equations. I'm gonna write them both down. So for the first we have s second is also s. But these are two different forms. These air Allah, tropic forms, Rumbek and model clinic again. Two different Allah tropic forms of sulfur. Both of these are reacting with whips. Oh, my g in the wrong spot, reacting with oxygen to produce. So for dioxide. And these are both gas now, my delta h For each reaction, they're very close, but they're not exactly the same. This is negative to 96.6 and this is negative to 96.36 when they have toe. I can't quite get those fitting on there. I'm going to set these up just a smidge differently. I'm gonna give you my dealt that H Further action right here. Negative to 96 0.6 Kill a Jules per mole and negative to 96 0.36 killer jewels per mole. And we are asked to combine these equations and find the change in entropy, the Delta H four transforming the Rahm Bic Rahm Bic to the Monarch clinic. Okay, In order to do that, we're going to call this equation one. Any equation, too? We're going to look at these two equations and arrange them so that we can get this as a result. So for equation number one equation number one contains the raw mix. So we're gonna leave this equation exactly as written. I didn't leave room for my always there. That's OK. And I have my s 02 g and my dealt the age is negative to 96 0.6 Gila jewels per mall. Okay, he could Nice. Big negative. There. Now, my second reaction. Let me switch colors. Here it my second reaction. I'm going to have to, if you will flip this, which means my products will become reactant. And that means I have to change my sign. So s 02 is now my product. Excuse me? My reactant and my products will be s I'm just gonna right mano and 02 and my delta H for this will now be positive to 96.36. And that's killing joules per mole. And then I need to add this whole equation. So when I'm adding this equation into cross out my owes that air on each side of my arrow cross out my S o twos and I get the Rumbek, the model clinic, and when I have negative to 96 0.6 plus positive to 96.36. Just a little low on space. Here. I'm gonna write that down underneath here. And then we could make it a funny little color. So to get my heat, I'm gonna take a negative to 96.6 plus my positive to 96.36. And my answer is 0.3 zero Kila jewels. So I'm gonna rate my answer. Appear again. 0.30 killer JAL's who One page
