A student extracts 6.3 g of water when performing the following combustion: C2H8 + 4O2 --> 2 CO2 + 4H2O If the theoretical yield is 8.6, what is the percent yield?

Question 2 Marks: 2 How many grams of oxygen gas must react to give 174.3 grams of ZnO according to the balanced equation. 2 Zn(s) + O2(aq) --> 2 ZnO(s)

How many grams of silver nitrate must react to give 67.5 grams of Ag according to the balanced equation. Cu(s) + 2 AgNO3(aq) --> Cu(NO3)2(aq) + 2 Ag(s)

How many grams of zinc must react to give 13.0 grams of ZnO according to the balanced equation. 2 Zn(s) + O2(aq) --> 2 ZnO(s)

Question 9 Marks: 2 In the reaction: Zn + 2 HCl ZnCl2 + H2 An excess of Zn is reacted with 300.0 g of HCl. How many grams of H2 will be produced?

How many chlorine atoms are contained in a 1.00 g sample of iron(III) chloride, FeCl3? Use the masses to two decimal places from the chart in the front of your text. Use the format 6.02E23 for 6.02 x 1023, or 6.02E-23 for 6.02 x 10-23,use two decimal plac...

why is it important that the equations be balanced when performing mass-mass stoichiometry problems?

What is the mass of iron (g) produced from 227.4 of iron(III) oxide ?

__Fe2O3(l) + __CO(g)----1500 degrees Celsius--->__Fe(l) + CO2(g)

So I need to multiply 6.02E23 by 3?
