WebAnswer: Thus, vapor pressure of solution = 0.9 X 0.459 = 0.4131 atm. Answer: The vapor pressure of pure ethanol at 60 °c is 0.459 atm. Raoult's law predicts that a solution prepared by dissolving 10.0 mmol naphthalene (nonvolatile) in 90.0 mmol ethanol will have a vapor pressure of 0.4131 atm. WebFeb 11, 2024 · I got 0,666 mol 1. write the equation of the reaction and balnce it 4 Fe(s) + 3 O_2(g) -> 2 Fe_2O_3(s) If you have problems with balancing this chemical equation, here is the whole process explained: …
How would you balance the following equation: Fe+O2 --> Fe2O3?
WebRust, Fe2O3, form from the reaction of iron and oxygen in the following equation: Fe (s) + O2 (g) → Fe2O3 (s) (Molar mass: Fe:55.9, O:16) . How many grams of O2 are needed to produce 29.8 g of Fe2O3? Molar mass Fe2O3 = 2*55.85 + 3*16 = 159.7 g/mol 159.7 g Fe2O3 contains 3*16 = 48 g oxygen WebP4 + O2 → P2O5 2. Mg(OH)2 + HCl → MgCl2 + H2O 3. Ba(NO3)2 + (NH4)2SO4 → BaSO4 + NH4NO3 4. Fe + NaBr → FeBr3 + Na5. Al + O2 → Al2O3 Explanation: To balance a chemical equation, you must keep in mind that the total number of each atom in the reactant side is equal to the total number of each atom in the product side. first women at west point
