In the reaction sn plus 2hf -- snf2 plus h2 What is the maximum amount of snf2 that can be produced when 0.480 moles of sn are mixed with 0.720 moles of hf?
0.36 moles of SnF2
How many moles of hydrogen produced when 6.75 moles of Sn react?
Sn + 2H+ --> Sn2+ + H2So 6.75 mol Sn reacts and is producing an EQUAL amount of hydrogen gas: 6.75 mol H2
How many moles of water are formed with 230 moles of H2 and 110 moles of O2?
2H2 + O2 --> 2H2OAs you can see by the balanced reaction, for every 1 mole of oxygen used, 2 moles of water are formed. Also notice that for every 1 mole of oxygen used, you need 2 moles of hydrogen to produce the 2 moles of water. So in your case 110 moles of oxygen would produce 220 moles of water & would also require 220 moles of hydrogen (which you have in excess since you have 230 moles of hydrogen). So 220 moles of water are the most that can be formed.
How many moles of tin can be produced from the electrolysis of SnCl2 if 1 Faraday of electricity is passed?
.5 moles of tin because the half reaction for tin is Sn+4 + 2e- -> Sn+2 since there are 2 electrons needed, for one mole of Sn, 1 faraday would only produce a half of a mole of Sn.
How much tin metal will react with 32.0mL of a 1.75M solution of hydrochloric acid to produce hydrogen gas?
I assume by " much " you mean grams tin. Balanced equation first.Sn + 4HCl -> SnCl4 + 2H2Now, find moles HCl by......Molarity = moles of solute/Liters of solution ( 32.0 ml = 0.032 Liters )1.75 M HCl = X moles/0.032 liters= 0.056 moles HCl=============== Now,0.056 moles HCl (1 mole Sn/4 moles HCl)(118.7 grams /1 mole Sn)= 1.7 grams of tin-----------------------
What is 2.20 moles of Sn converted into mass grams?
The number 2.20 moles of Sn equals 261.14 grams. This is a taught in biology.
In the reaction sn plus 2hf -- snf2 plus h2 What is the maximum amount of snf2 that can be produced when 0.480 moles of sn are mixed with 0.720 moles of hf?
0.36 moles of SnF2
How many atoms are in 2.09 moles of Sn?
2.09 moles Sn (6.022 X 10^23 atoms / 1 mole Sn) = 1.26 X 10^24 atoms of tin
How many moles of hydrogen produced when 6.75 moles of Sn react?
Sn + 2H+ --> Sn2+ + H2So 6.75 mol Sn reacts and is producing an EQUAL amount of hydrogen gas: 6.75 mol H2

What is age and value of British Bulldog serial 221-220 44 calibre revolver?
No sn data I can find. You will have to check on line auctions for prices.
Who can tell me the year of manufacture of a 220 swift serial 782-64034 Ruger M77 MackII?
Go to Ruger's website. They have a sn dating function you can use.
