Chemistry??! BIG HELP!?
6) How much C2H2 would be formed? Answer
in units of mol.
7) How much Ca(OH)2 would be formed? Answer in units of mol.
Acetylene gas (C2H2) used in welding, pro-
duces an extremely hot °ame when it burns
in pure oxygen according to the reaction
2C2H2(g)+5O2(g) ¡! 4CO2(g)+2H2O(g) :
How much CO2 is produced when 10000 g
of C2H2 burns completely? Answer in units
of g.
9) How much H2O is produced when 10000 g of
C2H2 burns completely? Answer in units of
g.
10) Laughing gas (nitrous oxide, N2O) is some-
times used as an anesthetic in dentistry. It is
produced when ammonium nitrate is decom-
posed according to the reaction
NH4NO3(s) ¡! N2O(g) + 2H2O(`) :
How much water is produced if 25 g of N2O
is produced in this reaction? Answer in units
of g.
11) 3:6 mol Fe(OH)3 and 6:6 mol H2SO4 react
according to the equation
2 Fe(OH)3 + 3H2SO4 ¡!
Fe2(SO4)3 + 6H2O:
If the limiting reactant is Fe(OH)3, deter-
mine the amount of excess reactant that re-
mains.
You are so smart - in fact, so smart that no one in THREE DAYS has even tried to answer your question. Perhaps you can take this question and apply it to another realm:
