Because of the plates crashing into each other
It's being dissolved so it's the solute
Answer:
The value of Gibbs free energy of the reaction is negative which means that reaction is spontaneous.
Explanation:
ΔG° = ΔH° - TΔG°
Where:
ΔG° = Change in Gibbs free energy at T temperature
ΔH° = Enthalpy of reaction at T temperature
ΔS° = Entropy change of reaction at T temperature
- The reaction with negative value of Gibbs free energy are spontaneous.
- The reaction with positive value of Gibbs free energy are non spontaneous.
A → B ,ΔG° = -40
The value of Gibbs free energy of the reaction is negative which means that reaction is spontaneous.
Answer:
5.05 × 10²⁴ Zn Atoms
Explanation:
In order to find the number of atoms we will follow these two steps;
Step 1: <u>Finding out the moles of Zn as;</u>
Moles = Mass / A. Mass
Moles = 549 g / 65.38 g/mol
Moles = 8.397 moles
Step 2: <u>Calculating No. of Atoms as:</u>
According to Avogadro's Law, each mole contains 6.022 × 10²³ particles. These particles can be any entity i.e. atoms, molecules, formula units, ions e.t.c. So,
No. of Atoms = Moles × 6.022 × 10²³ atoms/mol
No. of Atoms = 8.397 mol × 6.022 × 10²³ atoms/mol
No. of Atoms = 5.05 × 10²⁴ Zn Atoms
Answer:
587.5 L (Option A)
Explanation:
The reaction is:
2 C₈H₁₈ + 25O₂ → 16CO₂ + 18H₂O
We know that in STP conditions 1 mol of any gas is contained in 22.4L
Then, we can make a rule of three, to determine the moles of produced carbon dioxide.
22.4L is the volume for 1 mol
376 L will be the volume for (376 . 1) 22.4 = 16.78 moles at STP conditions.
Stoichiometry is 16:25.
16 moles of CO₂ are produce by the reaction of 25 moles of O₂
Then, 16.78 moles of CO₂ were produced by (16.78 . 25) /16 = 26.2 moles.
Now, the rule of three again.
1 mol of oxygen gas is contained at 22.4L, at STP conditions
26.2 moles might be contained at (26.2 . 22.4)/1 = 587.5 L
