It's D. Stretching opens up arteries. This makes blood more able to get through and lowers blood pressure. Stretching makes your muscles ready for an exercise. Improved circulation is just like lowering blood pressure because it opens up arteries, veins, and capillaries. D is wrong because stretching doesn't make your heart stronger. I hope this helps! :)
He is far sided ik this cuz I am near sided which is the opposite of far sided so your answer is far sided
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
