  • [FREE] Iron(III) oxide reacts with carbon to give iron and carbon . . .
    In the chemical equation Fe2O3(s) + 3C(s) → 2Fe(s) + 3CO(g), it shows that Fe2O3 reacts with C in a 1:3 ratio Therefore, to calculate the amount of carbon needed to react with 30 8g of Fe2O3, we first need to find out the molar mass of Fe2O3 which is approximately 159 7g mol Dividing 30 8g by this, we will get the number of moles of Fe2O3
  • How many moles of Fe are needed to react with 1. 00 moles of O 2
    4 Fe + 3 O2 → 2 Fe2O3 For 4 moles Fe we need 3 moles O2 to produce 2 moles Fe2O3 Step 3: Calculate moles Fe For 4 moles Fe we need 3 moles O2 to produce 2 moles Fe2O3 For 1 00 moles O2 we need 4 3 * 1 00 = 1 33 moles Fe There will be produced 0 67 moles Fe2O3 We need 1 33 moles of Fe

    The molecular weight of Fe2O3 is 55 8452+15 99943 = 159 69 g mol Molecular weight of C = 12 01 g mol16 5g Fe2O3 = 16 5 159 69 = 0 10347 mol of Fe2O3 According to the equation: Fe2O3 + 3C → 2Fe + 3CO1 mol of Fe2O3 requires 3 mol of C0 10347 mol of Fe2O3 requires 0 10347 x 3 mol of C= 0 31042 mol of C
  • Use the chemical equation to complete the activity. - Brainly. com
    12 grams of iron oxide (Fe2O3) will be produced from the reaction between 15 4 grams of iron and 3 6 grams of oxygen, with oxygen acting as the limiting reactant The calculations are based on converting grams to moles, determining the limiting reagent, and then translating the produced moles back into grams
  • [FREE] How many grams of Iron (III) oxide (Fe_2O_3) can be produced . . .
    Final answer: To find out how many grams of Iron (III) oxide (Fe2O3) can be produced from 25 0 g of iron, we calculate the number of moles of iron, use the stoichiometric ratio from the balanced equation, and then convert the moles of Fe2O3 to grams to get the final yield of 35 68 g of Fe2O3
  • [FREE] \text {Fe}_2\text {O}_3 + \text {CO} \rightarrow \text {Fe . . .
    That is the Fe2O3 mole ratio: Because Fe is a** 1:2** element, the mole of Fe is 2x2=4 moles Because the mole ratio of Fe2CO3 to CO2 is 1:3, the moles of Co2 are 2 x 3 = **6 moles ** Thus, If 2 moles of Fe2O3 react with 9 moles of CO, moles of each product is formed will be** 6 moles ** For more details regarding moles, visit: brainly com
  • [FREE] \text {Fe}_2\text {O}_3 + 3\text {CO} \rightarrow 2\text {Fe . . .
    In the chemical reaction Fe2O3 + 3CO → 2Fe + 3CO2, the substance that is oxidized is CO (carbon monoxide), as the oxidation number of carbon increases from +2 to +4 The substance that is reduced is Fe2O3 (iron(III) oxide), because the oxidation number of iron decreases from +3 in Fe2O3 to 0 in Fe (iron metal)
