Answer:
The added energy in the hot water causes water molecules to move faster and sucrose molecules to vibrate faster.
Explanation:
This added movement tends to make the bonds between sucrose molecules easier to overcome.
Hope it helps :-)
Answer:2.27 g H2O
Explanation:
Step 1. Get the limiting reagent
1.24 atm of H2 would react completely with 1.24 x (1/2) = 0.62 atm of O2, but there is more O2 present than that (0.98). O2 is in excess and H2 is the limiting reactant.
If the reaction goes to completion:
(1.24 atm H2) x (2 mol H2O / 2 mol H2) = 1.24 atm H2O vapor
n = PV / RT = (1.24 atm) x (2.5 L) / ((0.08205746 L atm/K mol) x (28 + 273)K) = 0.126 mol H2O
(0.126 mol H2O) x (18.01532 g H2O/mol) = 2.27 g H2O
Answer:
The IUPAC name of CH3 – CH2 – CH2 – CH=CH2 is Pent-1-ene.
