Question

Challenge Titanium is a transition metal used in many alloys because it is extremely strong and lightweight. Titanium tetrachloride $\left(\mathrm{TiCl}_{4}\right)$ is extracted from titanium oxide $\left(\mathrm{TiO}_{2}\right)$ using chlorine and coke (carbon). $$\mathrm{TiO}_{2}(\mathrm{s})+\mathrm{C}(\mathrm{s})+2 \mathrm{Cl}_{2}(\mathrm{g}) \rightarrow \mathrm{TiCl}_{4}(\mathrm{s})+\mathrm{CO}_{2}(\mathrm{g})$$ a. What mass of $\mathrm{Cl}_{2}$ gas is needed to react with 1.25 $\mathrm{mol}$ of $\mathrm{TiO}_{2} ?$ b. What mass of $C$ is needed to react with 1.25 mol of TiO $_{2} ?$ c. What is the mass of all of the products formed by reaction with 1.25 $\mathrm{mol}$ of $\mathrm{TiO}_{2} ?$

00:01 Okay, so we're given the chemical equation i'm written right here.

00:06 And what else have i got? we said, what mass of chlorine gas is needed to react with 1 .25 moles of titanium dioxide? okay, so there's three questions that we're going to do.

00:44 But that's our first question.

00:46 So, 1 .25 moles.

00:49 Is this a balanced chemical equation? yes, it is.

00:54 Of titanium dioxide will require one mole and two moles.

01:12 And i believe that's 70.

01:13 Is it 90 or 91? let me get to my molar mass tab.

01:24 Clor, oops, chlorine.

01:28 And i believe it's 70 .90.

01:31 Oops.

01:39 Let's see.

01:40 70 .90, i think it is 70 .91.

01:43 70 .91.

01:53 70 .91 grams per mole of chlorine.

02:02 We can report our answer to two significant figures based on our given.

02:11 And i get 177, did i say 3, 177 grams of chlorine.

02:22 Okay, second question out of 3.

02:25 What mass of c in grams for 1 .25.

02:38 Moles of titanium dioxide.

02:45 It's going to be the exact same calculation with a different mole ratio.

02:53 I should say exact same format, obviously...
