Chemistry Lab/Physical Properties

The molar heat capacity is also intensive, but is based on heat capacity per unit amount instead of mass Specific heat is often used in calorimetry (See: Chem Lab/Thermodynamics) to calculate heat transfer [math]q = m\cdot \Delta T\cdot C_p[/math], where q represents heat flow A notable specific heat is that of water, 4184 J/g*K or 1 Cal/g ....

Sodium nitrate | NaNO3

In humans, ingested nitrate is rapidly absorbed from the proximal small bowel and distributed throughout the body Nitrate then enters the large bowel from the blood, where it is rapidly converted to highly reactive nitrite, in part by fecal microorganismsThe formed nitrite is reabsorbed into the blood, where it reacts with the ferrous (Fe2+) iron of deoxyhemoglobin, forming methemoglobin ....

Ammonium sulfate

Us The primary use of ammonium sulfate is as a fertilizer for alkaline soilsIn the soil the ammonium ion is released and forms a small amount of acid, lowering the pH balance of the soil, while contributing essential nitrogen for plant growth The main disadvantage to the use of ammonium sulfate is its low nitrogen content relative to ammonium nitrate, which elevates transportation costs...
