What is the mass in grams of 4.5 moles of h2o?
0.25 mole of H2O
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 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 does 81 n on a s g mean?
"81 n on a s g" likely refers to "81 notches on a stock gauge." This phrase can indicate a measurement or marking system used in various contexts, such as woodworking, fishing, or manufacturing, where the notches represent specific values or increments.
