A member of a homologue series must poses a similar structure but differ in the ___ repeating unit.

how many molecules of h2o will form with 96.1 g of propane

When 11.8 of C8H18 underwent a combustion reaction with 8.84g of O2 it produced 1.15g of H2O. Balance the reaction and answer the following questions. What is the limiting reactant?

Calculate the standard molar entropy change for each of the following reactions at 25 ^oC.

1. Ca (s) + 2H₂O (l) → Ca(OH)₂ (aq) + 2H₂ (g)
2. Na₂CO₃ (aq) + 2HCl (aq) → 2NaCl (aq) + H₂O (l) + CO₂ (g)

Direction:Predict the shift in the equilibrium (direction: forward or reverse) of the reaction based on the application of stress.
