I believe it's (C) Endothermic reaction
Explanation:
When energy is absorbed in an endothermic reaction, the temperature decreases.
Salinity has units of grams NaCl or salt per kilogram solution. We can use the density given and the molar mass of the salt to convert from salinity to molarity. We do as follows:
( 5.6 g / kg ) ( 1.03 kg / L ) ( 1 mol / 58.44 g ) = 0.0987 mol NaCl / L
Answer:
(I hope this helps enough)
Explanation:
A wide spectrum of inorganic analytes are analyzed using redox titrimetry. By testing an unknown analyte against a standardized titrant, a redox titration (also known as an oxidation-reduction titration) can correctly calculate its concentration. It is used to determine the presence of organic analytes.
Answer: Solid ammonium chloride can be separated from a solid mixture of ammonium chloride and anhydrous chloride through the process of sublimation.
Explanation:
A process in which solid substance converts directly into gas without undergoing liquid state is called sublimation.
For example, when solid ammonium chloride is heat in the apparatus then it will convert directly into vapors without undergoing liquid state. During this process it leaves behind anhydrous chloride into the mixture itself.
When these vapors are cooled down at the surface of funnel then it gives ammonium chloride in the solid state.
Thus, we can conclude that solid ammonium chloride can be separated from a solid mixture of ammonium chloride and anhydrous chloride through the process of sublimation.
