What is the charge of iron in the iron oxide compound,
May 19, 2017 — 3+ Iron(III) oxide is a neutral compound, which implies the net charge of the compound equals 0; i.e. the charges of all the atoms must add up to 0. Oxygen in nearly all cases has a charge of 2- (except for a few compounds such as potassium superoxide, KO_2), so the total ionic charge the O atoms exhibit is 3(-2) = -6. If two Fe atoms equalize this charge and …
The standard heat of formation of Fe2O3(s) is 824.2kJ/mol
Sep 10, 2017 — DeltaH_(Rxn)^o = -1648.4 Kj Note, the Delta H_"f"^o(Fe_2O_3(s)) = - 824.2 "Kj"/"mole" (exothermic) The Standard Heat of Formation (DeltaH_(f)^o) is given in terms of Kj per 1 mole. By definition DeltaH_f^o is the heat liberated or gained on formation of one mole of substance from basic elements in their standard states. The Standard Enthalpy of Formation …
What is the oxidation number of iron in Fe_2O_3? - Socratic
Apr 16, 2018 — +3 So to find out the oxidation number of iron the iron oxide we start of by finding the oxidation number of oxygen and combine them. So we know that oxygen has a oxidation number of -2. Since we have 3 oxygens this would give a total of -6. We know that the charge should be stable (=0), so therefore iron must have a oxidation number of +3 since 2*3=6.
How would you balance the following equation: Fe+O2 - Socratic
Nov 2, 2015 — right side: Fe = 2; O = 3. Step 2: Start balancing the simple molecules first, in this case the O2. F e + 3O2 → F e2O3. left side: Fe = 1; O = 2 x 3 = 6. right side: Fe = 2; O = 3. Since there are now 6 O atoms on the left, there must also be 6 O atoms on the right. Notice that the right hand is one big molecule so whatever coefficient you ...
In the equation, Fe2O3 + 2Al → Al2O3 + 2 Fe, if 52.6 g of
Jan 9, 2018 — 155.85 g Let's consider the equation first. Fe_2O_3 + 2Al = Al_2O_3 + 2Fe It says that 2 moles of aluminium will react with 1 mole of Iron (III) Oxide to form 1 mole of Aluminium Oxide and 2 moles of Iron. So, Unitary method. 54 g Al will react with rarr 160 g of Fe_2O_3 1 g Al will react with rarr 160/54 g of Fe_2O_3 52.6 g Al will react with rarr (160 * 52.6)/54 g of …

Find the ΔH° for the reaction? a) Fe2O3(s)+3CO2(g)→2Fe(s
Aug 12, 2017 — For "Fe"_2"O"_3(s) + 3"CO"(g) -> 2"Fe"(s) + 3"CO"_2(g) you should get -"23.47 kJ/mol", if you use my numbers. Go look up numbers from your own book and try again... see what you get, and verify mine is correct. Well, when you manage to search your appendix for the substances in... "Fe"_2"O"_3(s) + 3"CO"(g) -> 2"Fe"(s) + 3"CO"_2(g) ...and you manage to fix …
What is the mass of 5 moles of Fe2O3 - Socratic
Feb 28, 2018 — O: 16.0gmol−1. Molar mass of F e2O3. = 55.8 ⋅ 2 + 16 ⋅ 3. = 159.6gmol−1. Which means that for each mole of F e2O3, it weighs 159.6g. Mass of 5 moles of F e2O3. = 159.6 ⋅ 5. = 798g. Answer link.
Balance the chemical equation FeSO4 - Fe2O3+SO2+SO3 - Socratic
May 29, 2018 — Explanation: Start by identifying the oxidation state for each of the element: +2 Fe+6 S−2 O4 → +3 Fe2−2 O3 + +4 S−2 O2 + +6 S −2 O3 − NOT BALANCED. Only three of the four chemicals- FeSO4, Fe2O3, and SO2 are directly involved in the redox reaction. The oxidation state of iron Fe has increased from. +2 in +2 Fe+6 S −2 O4 to.
