Answer:
The amount of heat is 84.4894kJ
Explanation:
Given data:
mass of octane=148g
The moles of octane is:
The melting point is=-56.82°C
ΔHfus=20.73kJ/mol
The heat of fusion is:
The heat to bring the octane to a temperature of 117.8°C is:
The total heat in the process is:
Qtotal=Qfus+Q₂=26.8578+57.6316=84.4894kJ
Answer:
1. Heating hydrogen gas from 60°C to 80°C: Entropy increases
2. Subliming dry ice: Entropy increases
3. Forming sucrose crystals from a supersaturated solution: Entropy decreases
4. Condensing water: Entropy decreases
Explanation:
Entropy is a measure of systems disorder. The higher the entropy the higher the disorder. So for the firs example if we heat a gas, molecules move faster, disorder is higher. For second example we are making disordered gas from very ordered crystals also increase in disorder. For 3rd example we are obtaining crystals which brings order. And for the fourth example we make liquid from gas which is also more order.
Answer:
Explanation:
The formula for photosynthesis is
6CO2 (Carbon Dioxide) + 6H20 (Water) + Sunlight -------> C6H12O6 (Glucose) + 6O2 (Oxygen)
in the reactants, we have the Carbon dioxide and Water and when the sunlight hit the chlorophyll, CO2 is reduced and form glucose which is C6H12O6 and water or H2O is oxidized to form Oxygen.
13.5 Moles Kcl x 6.022 x 10^23 /1
= 8.12 x 10^24
whenever you need to find molecules just multiply moles by avogadro number
