Answer:
3.0 mol H₂O
Explanation:
Step 1: Write the balanced combustion equation
C₂H₆ + 3.5 O₂ ⇒ 2 CO₂ + 3 H₂O
Step 2: Establish the appropriate molar ratio
The molar ratio of C₂H₆ to H₂O is 1:3.
Step 3: Calculate the moles of H₂O formed from 1.0 mole of C₂H₆
1.0 mol C₂H₆ × 3 mol H₂O/1 mol C₂H₆ = 3.0 mol H₂O
Answer is: distillation.
Solution of sugar and water has a uniform composition and is able to be separated by physical means.
Solution is homogeneous mixture has the same proporties of its components throughout any given sample.
Solution of water and salt, can be separated with distillation (process of heating and cooling). Water evaporates and sugar remain in the beaker.
