Problem 72

Calculate the mass (g) of each product formed when 43.82 $\mathrm{g}$ of diborane $\left(\mathrm{B}_{2} \mathrm{H}_{6}\right)$ reacts with excess water:
\mathrm{B}_{2} \mathrm{H}_{6}(g)+\mathrm{H}_{2} \mathrm{O}(l) \longrightarrow \mathrm{H}_{3} \mathrm{BO}_{3}(s)+\mathrm{H}_{2}(g)[\text { unbalanced }]

So we're keeping that we should be even for Hydra and water. So what would be the mass off Off called it when we have 33 48th 6 gram off up or hydra again. This reaction is no bounds. So that's a response. That first. So first of all, I would put out Sue you fend off, up or pour acid because we never have to pull over on the left. The next one I were chose. Dubai's are hostages. So for oxygen, I would put 16 from the water. Who I have Ah, six on the right from the boarding houses. So I have six. And on the laugh of our ah ha jin Ah, we were half 18. And on the right, we only have sex past. You have eight. So therefore we had to make sure we have 18. Oh, uh, Hodgins. So we have 60 already, so we just need to put a 16 fund over 100 we were half. Oh, the highs of being Bonner's. Okay, So, uh, Lex stab, we're going to Ah, proceed for with the calculations. First of all, I would feel fun of the lumber almost off. Ah, for high try. So I would just take 43 point a six gram divide by Arthur Borrow. Hi. Tried, uh uh more the mass. So we're plus six or 20 safe in 200.62 for them with the mess. And then we're 43.60 whereby and lovely. We will have 1.5. It upmost went for if I ate both. Okay, so, uh, for lumber, Most all for ob or acid and also for hydrogen. We can, um, use them well away. Show to find out. So we have the number one will be to excess. And h sake, Upper hard drive. You can see that. Um, the moolah visual between 400 also for SS 1 to 2. Prosecco efficient. This one and then the provisions too. So therefore, toe Mullah Ah, number most up our assets will be free 0.176 No. And therefore, um, hydrogen will be available by six. You will be named 0.35 to 8 mo. All right, so for the mask, you just need to multiply by the minimus. So for border asset, the mood of mass rupee. Ah, we have 300 in 14 and also ah free also Jin. So we will have a 61.81 61 point Anyone for the more than Mass and a modified by the by the number most. Then we have 1 96 appointed fleet Quinn for, uh for acid and therefore hydrogen everywhere will flying 0.5 to 8 most and then 100. It's ah 100 molecule will amass a revenue run too. So we're 19 point, uh, sell for 19.6 gram for hedging guests.
