H2S
⇒ 3
HNO3
⇒ 2
Works for EDG
changes in density
Explanation:
The global thermohaline (conveyor belt) circulation is caused by changes in global ocean density.
The ocean water density is determined by the temperature and salt content of the ocean (thermo - heat and haline - salt).
- Surface current drives warm and less water away for the equator towards the poles.
- At the poles they become cold and very dense sinking to the bottom and moving towards the equator back.
- It is also called the ocean conveyor belt

Answer:
B is False
Explanation:
In physical chemistry we always look from system's perspective, so if we heat something ΔH is positive and if the system gives heat out then ΔH is negative.
A. We have to give energy to benzene to evaporate it. Statement true.
B. If heat is absorbed then the enthalpy must be positive.
C. The heat is absorbed then ΔH is positive.
D. Usually for burning heat is exposed from system. So enthalpy is negative.
E. Obvious
Answer:
No, it is not appropriate to mix water and DMSO
Explanation:
We have to realize that DMSO is a highly polar solvent and water is a highly polar solvent. The question explicitly says that our target is to produce a solvent of<u><em> intermediate polarity</em></u>.
We can only do this by mixing a polar and a nonpolar solvent. We have been given the example of the mixture of acetone/hexane which is quite a perfect mixture.
Thus, it is inappropriate to mix DMSO and water.
