Responder:
<h2>1.892mol / L
</h2>
Explicación:
La molaridad se define como la relación del mol de una solución por litro de su solución.
Molaridad = Mole de soluto / solución (en litros)
La solución aquí es agua = 250 ml = 0.25L
El soluto es cloruro de potasio (KCl)
Para obtener el mol del soluto, usaremos la fórmula;
Mole del soluto = Masa de KCl / Masa molar de KCl
Masa dada de KCl = 35 g
Para la masa molar de KCl donde K = 39 g / mol y Cl = 35 g / mol
Masa molar de KCl = 39 + 35 = 74 g / mol
Mole del soluto = 35/74 = 0.473 mol
Molaridad = 0.473mol /
0.25L
Molaridad en la solución = 1.892mol / L
Answer:
An increased body temperature made changes to the T-cell membrane to fight certain temperature sensitive viruses or bacteria.
Explanation:
According to medical science, having fever or an increased body temperature helps the human body to fight certain temperature sensitive bacteria or viruses.
An experiment performed by the Chinese scientist, Jian Feng Chen of Shanghai Institute of Biochemistry on mice showed that the injected high temperature in the body of the mice stimulated the T-cell membrane which started secreting heat-shock protein or Hsps, which fights stress.
This study showed that the raised temperature triggers the body immune system to fight a virus or bacteria caused infection.
