Hydrogen gas and oxygen gas react to make water in 62% yield. If
100. g of hydrogen gas reacted with excess oxygen gas calculate the
actual yield of water in grams.
Must show work
H2(g)+ O2(g)→
2H2 O(g)
How many grams of water will be produced if there 5.0 gram of
oxygen?
How many moles of water will be produced if there are 2.0 moles
of hydrogen?
You conducted the above experiment in the lab and found that the
10.0 moles of water are produced, how many grams you actually
produced of water?
If you correctly done number 3, then it is your yield?
If you started out the experiment with...
When 1 [g] of Hydrogen is combined with 8 [g] of oxygen, water (H2O) is formed and 3 · 105 [J] of energy are released.
(a) Determine the amount of water formed.
(b) If a household consumes an average of 2.5 [GJ] per month (Giga = 109), determine how much mass
it would be necessary to transform into energy to cover that consumption.
For the following reaction, 3.80 grams of hydrogen gas are
allowed to react with 10.6 grams of ethylene (C2H4). hydrogen (g) +
ethylene (C2H4) (g) ethane (C2H6) (g)
What is the maximum amount of ethane
(C2H6) that can be formed?
What is the FORMULA for the limiting
reagent?
What amount of the excess reagent remains after the reaction is
complete
Methane, CH4, burns completely in oxygen to yield carbon dioxide
and water. 1. how many grams of carbon dioxide can be formed from
16.0g of methane and 48.0g of oxygen?
2. how much excess reagent will be left unreacted?
3. if only 30.0g of carbon dioxide are formed, what is the
percent yield of the reaction?
