Question

Balance and write conversions for each of the following based on the balanced equation: CH3OH +O2 => CO2 + H2O a. Using dimensional analysis, convert from 3.56 moles of CH3OH to the number of moles of O2 required. b. Calculate the number of moles of water formed when 15.0 moles of O2 completely react

Answer 1

a. To convert from moles of CH3OH to moles of O2, use dimensional analysis: 3.56 moles CH3OH = 3.56 moles O2. b. To calculate the moles of H2O formed, use the stoichiometric ratio: 15.0 moles O2 = 30.0 moles H2O.

Step-by-step explanation:

a. To convert from moles of CH3OH to moles of O2, we can use dimensional analysis. According to the balanced equation, 1 mole of CH3OH reacts with 1 mole of O2. Therefore, we can set up the following conversion: 3.56 moles CH3OH x 1 mole O2/1 mole CH3OH = 3.56 moles O2.

b. To calculate the number of moles of water formed when 15.0 moles of O2 completely react, we need to use the stoichiometric ratio from the balanced equation. From the equation, we can see that 1 mole of O2 produces 2 moles of H2O. Therefore, we can set up the following conversion: 15.0 moles O2 x 2 moles H2O/1 mole O2 = 30.0 moles H2O.
