Inhalants can be breathed in through the nose or the mouth in a variety of ways, such as—
"sniffing" or "snorting" fumes from containers;
spraying aerosols directly into the nose or mouth;
"bagging" — sniffing or inhaling fumes from substances sprayed or deposited inside a plastic or paper bag;
"huffing" from an inhalant-soaked rag stuffed in the mouth; and
inhaling from balloons filled with nitrous oxide.
Answer:
False
Explanation:
STI medication needs to be taken until the infection is 100 % gone. Symptoms can be gone, but the infection is still in the body.
Answer:
The change of existing human infections and creature infections. Infections recently restricted to little, secluded populaces that would now be able to spread because of mechanical or social changes, for example, the improvement of moderate worldwide travel.
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
