Wave A represents the child rapidly kicking his legs, Wave B represents the child who made the large splash. Wave A represents the child rapidly kicking his legs because the wave on the graph is fluctuating rapidly, while Wave B represents the child who made the large splash because it does not fluctuate as rapidly as Wave A.

What volume will be occupied by 33.0 grams of CO2 at 500 torr and 27 °C?

wlad13 [49]

Answer:

V = 27.98 L

Explanation:

Given data:

Mass of CO₂ = 33.0 g

Pressure = 500 torr

Temperature = 27°C

Volume occupied = ?

Solution:

Number of moles of CO₂:

Number of moles = mass/molar mass

Number of moles = 33.0 g/ 44 g/mol

Number of moles = 0.75 mol

Volume of CO₂:

PV = nRT

R = general gas constant = 0.0821 atm.L/ mol.K

Now we will convert the temperature.

27+273 = 300 K

Pressure = 500 /760 = 0.66 atm

By putting values,

0.66 atm×V = 0.75 mol × 0.0821 atm.L/ mol.K × 300 K

V = 18.47 atm.L/0.66 atm

V = 27.98 L

Place the following types of attraction weakest to strongest:

avanturin [10]

Answer: The order from weakest to strongest is:

$\text{dispersion forces}$

Explanation:

Dispersion force is the weakest intermolecular force. It is a temporary attractive force that come into action when the electrons in two neighboring atoms are at the positions which results in formation of temporary dipoles.

Dipole interaction is an attractive interaction between the positive end and negative end of the polar molecule.

Hydrogen bond is a weak bond between two adjacent molecules due to an electrostatic attraction between a hydrogen atom in a molecule with an electronegative atom of an adjacent molecule.

Single covalent bond is more stronger bond than the the interaction stated above because there is sharing of an electron between two atoms.

Ionic bond is the strongest bonds in which complete transfer of electrons is present. Due to high electronegativity difference between the bonded atoms there is a high electrostatic interaction between the oppositely charged ions which makes ionic bond strongest from all the other types of the bonds.

So, the order is:

$\text{dispersion forces}$
