How does wind develop

Chemistry
1 answer:
avanturin [10]3 years ago
8 0
It is caused by differences in the atmospheric pressure. When a difference in atmospheric pressure exists, air moves from the higher to the lower pressure area, resulting in winds that vary in speed. On Earth, air is also deflected by the Coriolis effect, except exactly on the equator.

Calculate the volume in liters of a 2.3*10^-6 mercury(I) chloride solution that contains of mercury(I) chloride . Round your ans
GalinKa [24]

Answer:

2.00x10⁵L

Explanation:

<em>...That contains 125g of mercury(I) chloride...</em>

<em />

The molarity, M, of a solution represents the moles of solute (Mercury(I) chloride), per liter of solution.

To solve this question, we need to determine the moles of mercury(I) chloride present in 125g. Then, with molarity, we can find the volume of the solution:

<em>Moles Mercury(I) chloride -Molar mass: 271.52g/mol-:</em>

125g * (1mol / 271.52g) = 0.460 moles

<em>Volume:</em>

0.460 moles * (1L / 2.3x10⁻⁶mol) =
