(HINT you need the balanced chemical reaction!)
A) 9.0 moles of O2 and produce 3.0 moles of Fe2O3
B) 9.0 moles of O2 and produce 6.0 moles of Fe2O3
4Fe + 3O2>> 2Fe2O3
Looks like a 3:2 ratio to me.
I just completed a titration lab and the balanced equation is (8H^+)+MnO4^- + 5Fe (^2+) ---> Mn + 4 H20 + 5 Fe(^3+) I'm supposed to calculate the moles of permanganate, Fe^2+ and the mass of iron from the sample. The volume of permanganate is 33.5, and the
How do catalysts affect a chemical reaction? lose activation energy provide activation energy increase activation energy lower activation energy*** What does the forward arrow in a chemical equation mean? The reaction is reversible. The reaction proceeds
Ammonia chemically reacts with oxygen gas to produce nitric oxide and water . What mass of ammonia is consumed by the reaction of 4.5g of oxygen gas? Round your answer to significant digits.
5. How many grams of iron oxide can be produced from 2.50 g of oxygen reacting with iron, according to the following equation? 2 Fe (s) + 3 O2 (g) -->2 Fe2O3(s)
iron (III) oxide is formed when iron combines with oxygen in the air. how many grams of Fe2O3 are formed when 16.7g of Fe reacts completely with oxygen? 4Fe(s) + 3O2(grams) => 2Fe2O3(s)
Write the balanced equation for vandadium (II) oxide with iron (III) oxide results in vanadium (V) oxide and iron (II) oxide. 2VO + Fe2O3 - V2O5 + 6FeO2 Not sure if the is correct. We're having to learn this on our own with just what notes we have,
The rusting of iron is represented by the equation 4Fe +3O2 --> 2Fe2O3. If you have a 1.50-mol sample of iron, how many moles of Fe2O3 will there be after the iron has rusted completely? a. 0.50 mol b. 0.75 mol c. 1.0 mol d. 1.50 mol e. 2.0 mol --> I got
the balanced equation for the reduction of iron ore to the metal using CO is Fe2O3+3CO(g) -> 2Fe+3CO so what is the maximum of iron in grams that can bbe obtained from 454g (1.00 lb) of iron (III) oxide? AND what mass of CO is required to react with the
the ratio of the distances a 7-iron and a 5- iron will dirve a golf ball is 5 to 6. if a golfer averages 153 yards with a 7- iron, how far should he averages with a 5-iron?
