Given the following data fe2o3 s 3co g --- 2fe s 3co2 g delta h -23 kj 3fe2o3 s co g --- 2fe3o4 s CO2 g delta h -39 kj fe3o4 s co g --- 3feo s CO2 g delta h 18 kj calculate delta h for the reaction?
Unfortunately, you did not specify what final chemical equation you wanted given these formulas. From the data though I assumed the following: Fe2O3(s) + 3CO(g) à 2Fe(s) + 3CO2 H1 3Fe2O3(s) + CO(g) à 2Fe3O4(s) + CO2(g) H2 Fe3O4(s) + CO(g) à 3FeO(s) + CO2(g) H3 3(Fe2O3(s) + 3CO(g) à 2Fe(s) + 3CO2) 3(H1) 2Fe3O4(s) + CO2(g) à3Fe2O3(s) + CO(g) -H2 2(3FeO(s) + CO2(g) à Fe3O4(s) + CO(g)) 2(-H3) 3Fe2O3(s) + 9 (6)CO(g) à 6Fe(s) + 9(6)CO2 3(H1) 2Fe3O4(s) + CO2(g) à3Fe2O3(s) + CO(g) -H2 6FeO(s) + 2CO2(g) à 2Fe3O4(s) + 2CO(g) 2(-H3) 6FeO(s) + 6CO(g) à 6Fe(s) + 6CO2 3H1 + -H2 + -2H3 FeO(s) + CO(g) à Fe(s) + CO2 [(3H1 + -H2 + -2H3) / 6] FeO(s) + CO(g) à Fe(s) + CO2 -11KJ/mol
What is the coefficient of carbon dioxide after balancing the following equation khco3 s k2co3 s h2o g co2 g?
The balanced equation is 2KHCO3(s) → K2CO3(s) + H2O(g) + CO2(g). The coefficient of carbon dioxide (CO2) in the balanced equation is 1.
If you have 25g of Zinc and 300g of Sulfur what is the mass of the excess reactant?
Zn + S ==> ZnSmoles Zn = 25 g x 1 mol/65.4 g = 0.38 moles Znmoles S = 300 g x 1 mol/32 g = 9.38 moles Smoles S in excess = 9.38 - 0.38 = 9.00 molesmass S in excess = 9 moles x 32g/mol = 288 g = 280 g (to 2 significant figures)
What is the electron affinity equation for S?
The electron affinity of sulfur (S) can be represented by the equation: [ \text{S(g)} + e^- \rightarrow \text{S}^-(g) + \Delta E ] Here, sulfur in its gaseous state (S(g)) gains an electron (e^-) to form a sulfide ion (S^-(g)), and ΔE represents the energy change associated with this process, which is typically negative, indicating that energy is released when the electron is added.
What the formula mass for H2S2?
To calculate the formula mass of H₂S₂ (hydrogen disulfide), you add the atomic masses of its constituent elements. Hydrogen (H) has an atomic mass of approximately 1.01 g/mol, and sulfur (S) has an atomic mass of about 32.07 g/mol. Therefore, the formula mass of H₂S₂ is calculated as follows: (2 × 1.01 g/mol) + (2 × 32.07 g/mol) = 2.02 g/mol + 64.14 g/mol = 66.16 g/mol. Thus, the formula mass of H₂S₂ is approximately 66.16 g/mol.
What scientist developed the fluid mosaic model?
The Fluid-Mosaic-Model describes the structure of the plasma membrane as a mosaic of components that gives the membrane a fluid character. The founders are S.J. Singer and Garth L. Nicolson.

Who proposed the fluid mosaic model of plasma membrane?
Gorter and Grendel in1925 published the results of experiments showing that lipids could form a double layer. Danielli and Davson in 1935 produced the first true model of the cell membrane, in which a lipid bilayer was sandwiched between two layers of protein. Bangham in 1965 showed that phospholipids could form spherical structures (liposomes).
The membrane is a mosaic of protein molecules bobbing in a fluid bilayer of phospholipids?
