A. Use your balanced equation to calculate the moles NO2 which are produced from 25.0g Cu. 25.0g Cu/ (63.5g/mol Cu) = 0.394mol Cu Use stoichiometric coefficients to calculate moles NO2 from moles Cu. 0.394mol Cu ( 2mol NO2 /1mol Cu) = 0.788mol NO2 Remember to put stoichiometric coefficient of known quantity in the denominator and desired quantity in numerator. For your question, mol Cu, cancels and gives you mol NO2. Now remember that 1.00mol of ant gas at STP occupies 22.4L, then 0.788mol NO2 occupies 17.6L which is answer c.

A. the equation 2 Al & 3 CuSO4 --> 1 Al2(SO4)3 & 3 Cu they are supposed to react 2 Al's ( 54 grams) with 3 CuSO4 ( 3 X 159.6g/mol = 478.8 grams) looking at the two sets of grams needed, they need about 9 times as many grams of CuSO4 , (478.8 grams), compared to the amount of Al needed (54grams) --- but since they didn't give 9 times as much CuSO4 when they gave the 66.55g , compared to the 10.45 g of Al given... the limiting reagent is the CuSO4 --- using molar masses & the equation: ? g Al2(SO4)3= 66.55g. of CuSO4 X 342.15 gAl2(SO4)3 / 478.8 g CuSO4 *first answer = produces 47.56 g Al2(SO4)3 --- ? g Cu = 66.55g. of CuSO4 X (3 x 63.55 g Cu) / 478.8 g CuSO4 *second answer= 26.50 g copper produced --- ? g Al = 66.55g.… [cont.]

A. No reaction will occur, since Iron is a more active metal than copper. A reaction would occur if iron were placed in copper (II) nitrate, then the reaction would be: Cu(NO3)2 + Fe --> Cu + Fe(NO3)2

Q. mass-energy stoichiometry problem: What mass of Cu reacts w/1500 kJ of energy if you have H2O+Cu+86.6kJ=H2+CuO
Asked by Catie C - Wed Mar 12 16:41:06 2008 - - 1 Answers - 0 Comments

A. Based on what you have written, we can merely divide 1,500 kJ with 86.6 kJ to find out the mol of Cu that reacted with H2O 1500. 1500/86.6 = 17.321 mol of Cu Since atomic weight of Cu is 63.546 g/mol, we compute for the mass: 17.321 mol (63.456 g/mol) = 1099.121 g Cu P.S. It would be wrong that to say that Cu reacts with energy, since it only reacts with water. However, energy is needed for the reaction to occur.

Asked by Amanda H - Wed Apr 30 18:03:36 2008 - - 2 Answers - 0 Comments

A. Look at the coeffecients on the balanced equation. If there isn't a coeffecient, it's assumed to be 1. There is 1 mole of Cu and 2 moles of Ag(NO)3 reacting to make two moles of Ag and one mole of Cu(NO2)3. So, for every mole of Cu, you'll get 2 moles of Ag. You react 3 moles of Cu, you'll end up with 6 moles of Ag. Hope this helps~

A. The atomic mass of Cu (63.55) is about 4 times that of O (16.00). Since the Copper Oxide is 88.9% copper by weight (2.5/2.81) or approximately 8/9. The ratio of copper to oxygen must be 2 to 1. So the formula would be Cu2O

A. First you need a balanced equation A2gNO3 + Cu == 2Ag + Cu(NO3)2 Now do the stoiciometry. Convert 0.241 Ag to moles and use the corect molar ratio to calculate moles of AgNO3. Once you have the moles, divide by .0738 L to get the molarity.
