The overall reaction in a commercial heat pack can be represented as shown below. 4 Fe(s) + 3 O2(g) 2 Fe2O3(s) ΔH = -1652 kJ How much heat is released when 4.00 mol iron is reacted with excess O2? How much heat is released when
Chemistry

Iron metal reacts with oxygen gas to produce iron(III) oxide. If you have 12.0 moles of iron, for complete reaction you need: (HINT you need the balanced chemical reaction!) A) 9.0 moles of O2 and produce 3.0 moles of Fe2O3 B) 9.0

Am I correct? Deterioration of buildings, bridges, and other structures through the rusting of iron costs millions of dollars everyday. Although the actual process also requires water, a simplified equation (with rust shown as

Chemistry

When iron (Fe) rusts (reacts with O2), the product is iron(III) oxide (Fe2O3). If 25 g Fe is reacted with 25 g O2 in a sealed container, what are the masses of Fe, O2 and Fe2O3 in the container after the reaction is complete? How

An iron ore sample contains Fe2O3 together with other substances. Reaction of the ore with CO produces iron metal: αFe2O3(s)+βCO(g)→γFe(s)+δCO2(g) A)Balance this equation. B)Calculate the number of grams of CO that can react
Chemistry

When 84.8 g of iron(III) oxide reacts with an excess of carbon monoxide, iron is produced. Fe2O3(s) + 3CO(g) ==> 2Fe(s) + 3CO2(g) what is the theoretical yield of iron?
Chemistry ( stoichiometry )

How many grams of iron can be made from 16.5g of Fe2O3 by the following equation: Fe2O3 + 3 H2 -----> 2 Fe + 3 H2O.
