Answer:

A thunderstorm is classified as “severe” when it contains one or more of the following: hail one inch or greater, winds gusting in excess of 50 knots (57.5 mph), or a tornado. ... There are about 100,000 thunderstorms each year in the U.S. alone. About 10% of these reach severe levels

Calculate the volume in liters required to prepare a 5.00 m solution of nacl using 15.4 g of nacl

Vedmedyk [2.9K]

<span>52.7 ml First, determine how many moles of NaCl you have Atomic weight sodium = 22.989769 Atomic weight chlorine = 35.453 Molar mass NaCl = 22.989769 + 35.453 = 58.442769 g/mol Moles NaCl = 15.4 g / 58.442769 g/mol = 0.263505653 mol Now molarity is defined as moles/liter, so let's set up an equation for the number of liters we can make. molarity = moles/liter Substitute the known values 5.00 = 0.263505653/liter And solve for liters 5.00 = 0.263505653/liter 5.00* liter = 0.263505653 liter = 0.263505653/5.00 liter = 0.052701131 So you can make 0.0527 liters of the solution. Or 52.7 ml</span>

The nonvolatile, nonelectrolyte DDT, C14H9Cl5 (354.50 g/mol), is soluble in diethyl ether CH3CH2OCH2CH3. Calculate the osmotic p

aleksandrvk [35]

Answer:

2.50 atm

Explanation:

We have 10.4 g of DDT (solute), whose molar mass is 354.50 g/mol. The corresponding moles are:

10.4 g × (1 mol/354.50 g) = 0.0293 mol

The molarity of the solution is:

M = moles of solute / liters of solution

M = 0.0293 mol / 0.286 L

M = 0.102 M

We can find the osmotic pressure (π) using the following pressure.

π = M × R × T

where,

R: ideal gas constant

T: absolute temperature

π = M × R × T

π = 0.102 M × 0.0821 atm.L/mol.K × 298 K

π = 2.50 atm

Which substance in each of the following pairs would you expect to have the higher boiling point? Explain why.

satela [25.4K]

Explanation:

Boiling point is defined as the temperature when the vapor pressure of liquid becomes equal to the atmospheric pressure surrounding the liquid. And, during this temperature liquid state of substance changes into vapor state.

More stronger is the presence of intermolecular forces within the molecules of a compound more heat is required by it to break the bond. Hence, boiling point will also increase.

(a) As both Ne and Xe are noble gases and has intermolecular dispersion forces. But as the atomic size of Xe is more than the atomic size of Ne and we know that dispersion forces increases with increase in size.

Hence, boiling point of Xe will be more than the boiling point of Ne.

(b) Both $CO_{2}$ and $CS_{2}$ are non-polar in nature with intermolecular dispersion forces. So, more is the molecular weight of a compound more heat will be required by it in order to break the bonds.

As molecular weight of $CS_{2}$ is more than the molecular weight of $CO_{2}$ . Hence, $CS_{2}$ will have high boiling point.

(c) Molecular weight of $CH_{4}$ is 16 g/mol and molecular weight of $Cl_{2}$ is 35 g/mol.

Hence, $Cl_{2}$ will have high boiling point due to the presence of high molecular weight as compared to $CH_{4}$ and more strong dispersion forces.

(d) $F_{2}$ is a covalent compound so, it will also be non-polar in nature. Hence, it has weak intermolecular dispersion forces. On the other hand, LiF is an ionic compound and it has strong intermolecular forces of attraction due to the presence of opposite charges on the combining atoms.

Hence, LiF will have high boiling point as compared to $F_{2}$ .

(e) Both $NH_{3}$ and $PH_{3}$ are polar molecules in which dipole-dipole forces does exist. Since, nitrogen atom is more electronegative than phosphorous atom so, it will have stronger hydrogen bonding and strong intermolecular forces.

Hence, $NH_{3}$ will have high boiling point as compared to $PH_{3}$ .
