Problem 68

Chlorine gas can be made in the laboratory by the reaction of hydrochloric acid and manganese(IV) oxide:
$$
4 \mathrm{HCl}(a q)+\mathrm{MnO}_{2}(s) \longrightarrow \mathrm{MnCl}_{2}(a q)+2 \mathrm{H}_{2} \mathrm{O}(g)+\mathrm{Cl}_{2}(g)
$$
When 1.82 mol of $\mathrm{HCl}$ reacts with excess $\mathrm{MnO}_{2},$ how many (a) moles of $\mathrm{Cl}_{2}$ and (b) grams of $\mathrm{Cl}_{2}$ form?

we have the reaction between the electric or acid and and then Oh, for Michael. So we have one point you to move off its CEO being going toe, We ever accept our manganese oxide? Damn reporters are Megan's core I water and Corey. So ah, for party. We're going to find out how What will be the limbo, More Caribbean, 40 years. And also what with the mass off Cohen being for deals. Okay, so for these questions, first of all, we have to make sure we have violence. And, um actually, we have to cancel with immigration bothers. So from there, from the coefficient of the chemical reaction ah, we can find out their corresponding motorway show. Well, the way show. Okay. So Ah, little at corps. Um hi, Joe. Cory Acid. We're four, and then we want to find out. Ah, Korean gas. The number more chlorine gas. So we look at that. It's one. So therefore, from here, the mullahs wish off hydrochloride acid to Korean gas will be close to force her 4 to 1. All right, so if the lumber most off a hydrochloric acid eyes one point a to mo. So what would be the lumber. Almost all Korean beanpole. Adios. So we know that the more you ratio is 4 to 1. So we just divide that by four, and then we should be able to find a sitter for 455 moles for Cohen and gas being poor deals. Okay, so this will be for A and M bonfire. Be the mass of Corinne gas. It will be. Ah, we're looking at Cohen Gas, and we just take the Lambo most with applied by the well, the mass off calling Cohen is a gas eyes. See out you. So come on. By that. Ah! 35.4 500 of the mass. Times two. And they were We have the masses. Your soup on 455 Time the off. Ah, 35.45 times two. So we would have furry two point, um, two crab for the myself. Korean being buddies
