<u>Answer</u>:
Organisms living near hydro-thermal vents get their energy from Sulphur.
<u>Explanation</u>:
The hot springs found near the Underwater volcanoes at convergent plate boundaries and spreading ridges are called as Hydro-thermal vents . The organisms that live near these hydro-thermal vents are capable of living in very hot water that has a temperature of 65°C to 100°C that would kill most surface organisms.
Also, organisms present at depth of the hydro-thermal vent are adapted to very high and extreme pressure. The water in this vent are very rich in Hydrogen Sulphide .This hydrogen sulphide has very rich amount of energy. Although the is toxic, the bacteria and other living organism are adjusted themselves to make use of the energy in the Hydrogen sulphide.
From the calculation, the molar mass of the solution is 141 g/mol.
<h3>What is the molar mass?</h3>
We know that;
ΔT = K m i
K = the freezing constant
m = molality of the solution
i = the Van't Hoft factor
The molality of the solution is obtained from;
m = ΔT/K i
m = 3.89/5.12 * 1
m = 0.76 m
Now;
0.76 = 26.7 /MM/0.250
0.76 = 26.7 /0.250MM
0.76 * 0.250MM = 26.7
MM= 26.7/0.76 * 0.250
MM = 141 g/mol

In Haber process, N₂ reacts with H₂ and produces NH₃. The balanced reaction for the Haber process is
<span>N</span>₂(g) <span>+ 3H</span>₂(g)<span> → 2NH</span>₃(g)
The stoichiometric ratio between N₂ and H₂ is 1 : 3
This means, reacted moles of N₂ = reacted moles of H₂ / 3
Hence, 3 moles of H₂ react with 1 mole of N₂ to form 2 moles of NH₃.
<u>Answer:</u> The new volume of the balloon will be 583.5 L
<u>Explanation:</u>
To calculate the volume when temperature and pressure has changed, we use the equation given by combined gas law.
The equation follows:
where,
are the initial pressure, volume and temperature of the gas
are the final pressure, volume and temperature of the gas
We are given:
Putting values in above equation, we get:
Hence, the new volume of the balloon will be 583.5 L
