Describe how would you prepare .005M solution of IO3^-1 starting with potassium iodate KIO3

Can someone pleas help I have this assignment and the only question I cannot figure out is to describe the hybridization of all the covalent bonds in oxalic acid? and label those bonds as sigma or pi bonds? I have determine that oxilic acid formula is HO_...

The thermal decomposition of potassium chlorate can be used to produce oxygen in the laboratory. What volume (L) of O2 gas at 25 °C and 1.00 atm pressure is produced by the decomposition of 7.5 g of KClO3 (s)? Here is my work: V=nRT/P .0611995 mol of O2 x...

Here is the question: sodium hydride reacts with excess water to produce aqueous sodium hydroxide and hydrogen gas: NaH(s)+H2O-->NaOH(aq)+H2(g) A sample of NaH weighing ________g will produce 982mL of gas at 28.0 C and 765 torr, when the hydrogen is colle...

Here is the question: Automobile air bags use the decomposition of sodium azide as their source of gas for rapid inflation: 2NaN3(s)-->2Na(s)+3N2(g) What mass (g) of NaN3 is required to provide 40.0 of N2 at 25.0 C and 763 torr? Here is my work: P=1.0039a...

Here is the question: A sample of an unknown volatile liquid was injected into a Dumas flask (mflask=27.0928g. Vflask=.104L) and heated until no visible traces of the liquid could be found. The flask and its contents were then rapidly cooled and reweighed...

The question: Formic acid when warmed with sulfuric acid, decomposes to water and carbon monoxide. HCHO2(l)-->H2O(l)+CO(g) If 3.85L of carbon monoxide was collected over water at 25C and 589mmHg, how many grams of formic acid were consumed? (This problem...

The problem: Nitrogen can react with steam to form ammonia and nitrogen monoxide gas. A 20.0L sample of nitrogen at 173C and 772mmHg is made to react with an excess of steam. The products are collected at room temperature (25C) into an evacuated flask wit...

I am thinking I need to work backwords on this problem so here is my math if anyone can confirm it for me that would be great. .005M IO3-1 * .5 Lsolutions = .0025 moles of IO3-1 Then I took .0025 mol IO3= .0025 mol KIO3 Then I took .0025 mol KIO3 * 214.00...

ingrimayne . com / econ / TOC . html HOPE THIS HELPS

i GOT THAT FROM TOP20ECONOMICS . COM i CANNOT PUT IN THE LINK i AM NEW TO THE SITE AND UNSURE WHAT THE RULES ARE SO I HOPE THIS DOES NOT GET US IN TROUBLE

I answered this in another post

Thank you

disregard, I found the answer

.0611995 mol of KClO3 needed to be converted to .09179925 mol of O2 b/c of the coeficients

Ok so I took the 1.01 atm H2 and subtracted the .03684atm H2O=.97316 Then put that in the equation I did earlier. n=PV/RT P=.97316 R=.0821 V=.982 L T=301.15 K (.97316atm H2)(.989L H2)/(.0821 Latm/mol L)(301.15k H2)==3505.383 mol H2 3505.383 mol H2 = 3505....

Thank you so much for sticking with me on this, for some reason I am putting the entire problem into my TI-83 and it is coming up with those large numbers. I do not get why it is doing that but now I got the right answer.

Once again thank you Bob, I think my brain is fried for the day. I would stop if I did not have 4 more questions to go. Hopefully I can get them on my own now that I figured out the calculator issues I was haveing.

Thank you that was exactly what I was looking for.

DISREGARD

Please disregard I finally figured it out.
