Alfheim
In Norse mythology it means home of Elves and it is known as home to the light elves
Answer:
Difference of the enthalpy (of a system) minus the product of the entropy and absolute temperature
Explanation:
The basis of spontaneity in a chemical reaction is that ∆G must be negative. ¡∆G is known as the change in free energy of a system. If ∆G is negative, then the reaction will occur without any external help (the reaction is spontaneous at room temperature).
∆G is given by;
∆G= ∆H -T∆S
Where;
∆H= change in enthalpy of the system
T= absolute temperature of the system
∆S= change in entropy
Hence; when ∆H -T∆S gives a negative result, the reaction proceeds without any external help.

Answer:
- 75.5 g O₂ (g) can be produced from 42.6 g of H₂O (g)
Explanation:
<u>1) Balanced chemical equation (given):</u>
<u>2) Mole ratios:</u>
- 2 moles H₂O(g) : 2 moles H₂(g) : 2 moles O₂(g)
<u>3) Calculate the number of moles of reactant (H₂0):</u>
- number of moles = mass in grams / molar mass
- molar mass of water: 18.015 g/mol
- mass in grams of water: 42.6 g
- number of moles = 42.6 g / 18.05 g/mol = 2.36 moles H₂O
<u>4) Set a proportion using the mole ratio O₂ to H₂O and the actual number of moles of H₂O:</u>
- 2 moles O₂ / 2 moles H₂O = x / 2.36 moles H₂O
<u>5) Convert 2.36 moles O₂ to grams:</u>
- mass in grams = number of moles × molar mass
- mass = 2.36 moles × 32.00 g/mol = 75.5 g O₂
