Answer:
Respiratory System:
Pathway of air: nasal cavities (or oral cavity) > pharynx > trachea > primary bronchi (right & left) > secondary bronchi > tertiary bronchi > bronchioles > alveoli (site of gas exchange)
Explanation:
47.0g is the mass of ammonia
Answer: vapor pressure of solution will be less than that of the pure solvent
Explanation:
Vapor pressure of a liquid is defined as the pressure exerted by the vapors in equilibrium with the liquid/solution at a particular temperature.
So, when a non-volatile solute is added to a solvent then its molecules align at the surface of liquid. As a result, less number of solvent molecules will escape from the solution. Thus, there will be decrease in vapors and thus the vapor pressure decrease.
As the relative lowering of vapor pressure is directly proportional to the amount of dissolved solute.
The formula for relative lowering of vapor pressure will be,
where,
= vapor pressure of pure solvent
= vapor pressure of solution
= mass of solute
= mass of solvent
= molar mass of solvent
= molar mass of solute
The United States Geological Survey estimates that there are around 50 earthquakes per day in the world that can be located. This amounts to around 20,000 earthquakes annually. Many earthquakes are undetected by the USGS; in fact, the organization estimates that around several million earthquakes occur around the globe annually.
