Answer:

See explanation

Explanation:

The S^2- ion is formed when sulphur atom accepts two electrons. Sulphur normally has six electrons in its outermost shell, it can however accept two more electrons to complete its octet and form the sulphide  (S^2-) ion.

The Lewis structure of the sulphide ion is shown in the image attached to this answer.

We consider a spherical air bubble rising through a water tank. The pressurepinside the bubble isequal to its surrounding pressu
DENIUS [597]

The answer is a change in internal energy causes work to be done and heat to flow into the system.  

<u>Explanation:</u>

Boyle's law says, PV=RT

  • Here P represents the pressure, V represents the volume and T represents the temperature. R is a constant. The volume of an ideal gas is inversely proportional to its pressure if the temperature is constant.
  • When a bubble is present in deep water it has water pressure and atmospheric pressure. Then the Volume increases when water pressure raises which is proportional to the depth reduces.
  • But we should not finalize the volume of the bubble will be four-time as great as at the top than the bottom.  if the bottom of the lake is at four atmospheres, the temperature will not be equal to the top.
  • If the bubble travels from the bottom to the top or vice-versa, it's going to lose or gain heat in a way that must be quite hard to measure.

If you have 16 g of manganese (II) nitrate tetrahydrate, how much water is required to prepare 0.16 M solution from this amount
nirvana33 [79]

<u>Answer:</u> The volume of water required is 398 mL

<u>Explanation:</u>

To calculate the molarity of solution, we use the equation:

\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}

We are given:

Mass of solute (manganese (II) nitrate tetrahydrate) = 16 g

Molar mass of manganese (II) nitrate tetrahydrate = 251 g/mol

Molarity of solution = 0.16 M

Putting values in above equation, we get:

0.16M=\frac{16g\times 1000}{251g/mol\times \text{Volume of solution}}\\\\\text{Volume of solution}=398mL

Hence, the volume of water required is 398 mL
