Problem 58 Hard Difficulty

Write balanced equations for each of the following by inserting the correct coefficients in the blanks:
(a) $_{-}\mathrm{SO}_{2}(g)+_{-} \mathrm{O}_{2}(g) \longrightarrow_{-}\mathrm{SO}_{3}(g)$
(b) $_{-}\mathrm{Sc}_{2} \mathrm{O}_{3}(s)+_{-}\mathrm{H}_{2} \mathrm{O}(l) \longrightarrow_{-}\mathrm{Sc}(\mathrm{OH})_{3}(s)$
(c) $_{-}\mathrm{H}_{3} \mathrm{PO}_{4}(a q)+_{-}\mathrm{NaOH}(a q) \longrightarrow{_{-}\mathrm{Na}_{2} \mathrm{HPO}_{4}(a q)+}_{-}\mathrm{H}_{2} \mathrm{O}(l)$
(d) $_{-} \mathrm{C}_{6} \mathrm{H}_{10} \mathrm{O}_{5}(s)+_{-} \mathrm{O}_{2}(g) \longrightarrow_{-} \mathrm{CO}_{2}(g)+_{-} \mathrm{H}_{2} \mathrm{O}(g)$


a) $2 \mathrm{SO}_{2}(\mathrm{g})+\mathrm{O}_{2}(\mathrm{g}) \longrightarrow 2 \mathrm{SO}_{3}(\mathrm{g})$
b) $\mathrm{Sc}_{2} \mathrm{O}_{3}(\mathrm{s})+3 \mathrm{H}_{2} \mathrm{O}(\mathrm{l}) \longrightarrow 2 \mathrm{Sc}(\mathrm{OH})_{3}(\mathrm{s})$
$\mathrm{H}_{3} \mathrm{PO}_{4}(\mathrm{aq})+2 \mathrm{NaOH}(\mathrm{aq}) \longrightarrow 2 \mathrm{H}_{2} \mathrm{O}(\mathrm{l})+\mathrm{Na}_{2} \mathrm{HPO}_{4}(\mathrm{aq})$
$\mathrm{C}_{6} \mathrm{H}_{10} \mathrm{O}_{5}(\mathrm{s})+6 \mathrm{O}_{2}(\mathrm{g}) \longrightarrow 6 \mathrm{CO}_{2}(\mathrm{g})+5 \mathrm{H}_{2} \mathrm{O}(\mathrm{g})$

we have to bounce off the chemical reaction on this page for partner. Where s 02? We have Griffo, true to form S O FOI. So that's starving about Ah ah, element that it's not only press and in one of the reaction and also only a present is one of the reaction. So it would be a cell for so for sulfur Ah, we can see that s 02 And as Sophie really have one sulfur so we don't have to do anything to balance that. Okay, so and then we'd be all station also Ginger's, they'll be complicated over here. Okay, But when we leave this reaction, we can see that if we have one s o to mark you Ah, when you went so to convert us 03 we only need you. Ah, one Austrian. But we we have also jin gas over to oppress. And so we're going to put a 1/2 over here to show that we only need one hostage. They want also here. Ah Forman Zinc chemical reaction. You can you can actually just fraction You can answer your freshen, but ah, sometimes you may not make the collision of two be complicated, but we can still convert that to the whole number. So we know that if we just put when have you from the oxygen, then dove? Chemical reaction respondents. And we want to We move that, um freshen. So we're going to multiply the whole thing by the whole reaction by two. So we were happy to us. Hopefully 102 And also to s awfully I mean, to ask you to We've 102 and two s awfully. And this is the band's Camco Asher. Okay, so for the B ah, we are going to balance the temple reaction again. We started something that element that we only find in the western and the products. So we're at sea. On the left were two sc on the right will have one. So where the two to your fellow asi Second, we're going to bands. Um, I would chose hydrogen because also can be a fine, you know, bills. We acted. So it will be We have to really change oxygen. We have to consider too variable. So we suffered Hodgins sound of right. We have to time sweetie studio as the six hydrogen six hydrant. So I'm going to put three in front off water to you know, the Banesto's Hodgins. Okay, so, uh, we're going to check, um, Austin. So on the left, we have three oxygen and one oxygen from water. Where four on the right way up to ah times three oxygen. So it will be six or seven just Well, so also responds. So this chemical reaction is violence. Okay, So, process we were actually pure for any Oyj and also become any to HBO for an h 20 Okay, So for this case, I will again chose Ah, element that only present in the western with regret and wanted the part that I was sorry force for. Okay, False for one force for left, one for writers, all battles. We don't have to do anything about that. And then the Lexx one I'm gonna buy a thing I'm going to borrow. This would be their sodium. So on the right, we have to sodium sided with two. So the involved that okay, the and then we can check off the, um Austrian and Ha jin. So, uh, for, um ah, Sophie for oxygen on left. We have Ah, four past tooth six on the right. Wherefore in force for? So we're going to put you in front or h 20 You know that the bonds also gin and then we can also intractable hydrogen. We have actually plus. Ah, you have five left. And then we also have fired her. Right? So is it is already upon us a swell. Okay, so we pointed. Last one. We have C six external, five per solitude to becomes the situation too old. So we go again. We were going to buy us humping first. So we just with 16 Philo CEO too, because we're six carbon and then for hydrogen. We have 10 on the river water. So we just verify your fund off water to partners. All the Hodgins. Okay, so on the left, we still have five hydrogen left on the rear areas. 12 Austria, 12 oxygen, and that we have five oxygen. So in total were 17. We have 17 so we have five hostages already, So we're just such right that we need 6 12 more oxygen of loving another imbalance. That so we're going to persist in for the Austrian £2 a whole chemical reaction. You see that
