5 0
Depression can affect a person psychologically, it also has the potential to affect physical structures in the brain. These physical changes range from inflammation and oxygen restriction, to actual shrinking. Depression can impact the central control center of nervous system. Depression can cause amygdala to enlarge. This is a part of the brain associated with emotional responses. When amygdala becomes larger and more active, it causes sleep disturbances, changes in activity levels, and changes in other hormones.

A graduated cylinder has a mass of 50 g when empty. When 30 mL of water is added, the graduated cylinder has a mass of 120 g. If
Verdich [7]

Answer:

2.9g/cm^3

Explanation:

We're given that the mass of the system before the rock was added was  

120g . The mass after the rock was added was  250g, so the rock's mass is 130g.

The initial volume of water in the graduated cylinder was  

30 mL , and the volume after the rock was added read  75mL , so the rock's volume is 45mL

Density = Mass over Volume.

AKA. 130g/45mL

2.9g/cm^3 (rounded)

MULTIPLE CHOICE<br> What is the molality (m) of 3.5 mol of sugar in 2.5 kg of water?
otez555 [7]

The molality of the solution is 1.4 moles per kilogram (molal).

The molality of the solution is equal to the number of moles of sugar (solute) divided by the number of kilograms of water (solvent). Hence, the molality is determined below:

m = \frac{3.5\,mol}{2.5\,kg}

m = 1.4\,\frac{mol}{kg}

The molality of the solution is 1.4 moles per kilogram (molal).

We kindly invite to check this question on molality: brainly.com/question/4580605

Calculate the number of mg of Mn2+ left
soldi70 [24.7K]

Answer:

1.930 * 10⁻⁹ mg of Mn⁺² are left unprecipitated.

Explanation:

The reaction that takes place is:

Mn⁺² + S⁻² ⇄ MnS(s)  

ksp = [Mn⁺²] [S⁻²]

If the pksp of MnS is 13.500, then the ksp is:

ksp=10^{-13.500}=3.1623*10^{-14}

From the problem we know that [S⁻²] = 0.0900 M

We use the ksp to calculate [Mn⁺²]:

3.1623*10⁻¹⁴= [Mn⁺²] * 0.0900 M

[Mn⁺²] = 3.514 * 10⁻¹³ M.

Now we can calculate the mass of Mn⁺², using the volume, concentration and atomic weight. Thus the mass of Mn⁺² left unprecipitated is:

3.514 * 10⁻¹³ M * 0.1 L * 54.94 g/mol = 1.930 * 10⁻¹² g = 1.930 * 10⁻⁹ mg.
