The energy that is released in the hydrogen fusion reaction comes from the difference in mass between the 4 hydrogen H nuclei and single helium He nucleus
The answer is: The difference in mass between the four hydrogen nuclei and single helium nucleus
Change in Gibb's free energy of system (ΔG) = ΔH - TΔS.........(Eq. 1)
Now, if magnitude of ΔG <0, then reaction is spontaneous.
if magnitude of ΔG > 0, then reaction is non-spontaneous.
At equilibrium, ΔG = 0
When at boiling point, liquid state is in equilibrium with vapour state. Hence, it present case ΔG = 0
∴ Eq 1 becomes, ΔH = TΔS
here, ΔH = 58.2 kj/mol (Given),
∴ At T = 83.4 oC = 356.4 K, ΔS = 0.1633 kj/mol.K
Answer:
Most compounds of Rubidium are formed by ionic bonds.
Explanation:
<h3>Mol of methanol =12.35</h3><h3>Further explanation</h3>
Mole itself is the number of particles contained in a substance
1 mole = 6.02.10²³ particles
Mole : the ratio of the amount of substance mass and its molar mass
Molarity is a way to express the concentration of the solution
Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution
Molar concentration of methanol=24.7 M
Volume of solution = 500 ml = 0.5 L
