To supply oxygen to the body, the respiratory system works closely with the circulatory system. As oxygen is taken in into the lungs, it travels through blood vessels, which then circulate oxygen-rich blood to cells and tissues.
Answer:
0.446
Explanation:
ccu = 3035.655 / 104 g x (98.9 - 33.5) = 0.446 J / g 0 C
B) Ksp = 3.7 E-11
CaF2 ↔ Ca2+ + 2F-
S S 2S,,,,,,,,,,,,,,,in the equilibrium
⇒ Ksp = [ Ca2+ ] * [ F- ]²
⇒ Ksp = S * ( 2S )²
⇒ Ksp = 4S³
⇒ Ksp = 4 * ( 0.00021 )³
⇒ Ksp = 4 * 9.261 E-12
⇒ Ksp = 3.704 E-11

LiCl2 3 M =
in sol. 1 L there is LiCl2 3 mol
if sol. 0.5 L there is LiCl2 0.5×3 = 1.5 mol
LiCl2 = 6.9 + 35.5(2)
= 6.9 + 71
= 77.9 g
