Is the climate change that Greenland is experiencing and will continue to experience a good thing or bad thing for Greenland and

KATRIN_1 [288]

Answer:

bad thing.

Explanation:

most of Greenland is an icy island with the only main population on the west coast.

Although this would probably open up more land for use; the rising sea levels are a much bigger threat comparatively with the perks of warmer climate.

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

A reaction between liquid reactants takes place at - 11.0 degree C in a sealed, evacuated vessel with a measured volume of 45.0

Sati [7]

Explanation:

The given data is as follows.

T = $11^{o}C$ = (11 + 273) K = 284 K, V = 45.0 L

m = 35 g

As molar mass of chlorine pentafluoride is 130.445 g/mol. Hence, number of moles of chlorine pentafluoride are as follows.

No. of moles = $\frac{mass}{\text{molar mass}}$

= $\frac{35 g}{130.445 g/mol}$

= 0.268 mol

Now, using the ideal gas equation we will find the pressure as follows.

PV = nRT

$P \times 45.0 L = 0.268 mol \times 0.082 L atm/mol K \times 284 K$

P = 0.139 atm

Thus, we can conclude that pressure of chlorine pentafluoride gas in the given reaction vessel after the reaction is 0.139 atm.
