Greater than 23mcg/dl is considered a high level of morning cortisol.
Normally, cortisol levels rise during the early morning hours and are highest about 7AM. They drop very low in the evening and during the early phase of sleep. If you do not have this daily change (diurnal rhythm) in cortisol levels, you may have overactive adrenal glands. This condition is called Cushing's syndrome.
Explanation:
magnetic separation is used for the iron fillings and sodium chloride
The iron fillings will stick to the magnet
then evaporation can help to remove water
Answer:
80.7 L
Explanation:
PV = nRT
P = 1520 mmHg = 2 atm
n = 5 mol
R = 0.08206 (L * atm)/(mol * K)
T = 393.15 K
2 (V) = 5 (0.08206) (393.15)
V ≈ 80.7 L
Answer:

Explanation:
Initial pressure, P = 125 kPa
Initial temperature, T = 25.0°C
If new pressure is increased to P' = 150.0 kPa
We need to find new temperature. According to Gay-Lussac's law,
P ∝ T
or

So, the new temperature will be
.
KOH + H2SO4 —> K(+) + HSO4(-) + H2O
Or a total reaction
2 KOH + H2SO4 —> 2 K(+) + SO4(2-) + 2 H2O
