What are the intermolecular forces between molecules in a liquid sample of sulfur trioxide, SO3?

1 answer:

7 0

The intermolecular forces between molecules in a liquid sample of sulfur trioxide, SO3 is London dispersion force.

<h3>What is intermolecular force? </h3>

The electrostatic forces of attraction present between molecules which hold them together are termed as intermolecular force.

<h3>Types of intermolecular force</h3>

Dipole dipole interaction
Dipole induced dipole interaction
van-der waal interaction
london dispersion force

<h3>What is london dispersion force? </h3>

This type of forces arises between symmetrical non- polar molecules. At a particular instant of time, the symmetry of molecules break and become unsymmetric. One side contain more electron than other. Having more electron become negative and other side get negative.

This unsymmetry make neighbouring molecule unsymmetric. The weak dispersion bond is formed between molecules called london dispersion force.

Thus, intermolecular forces between molecules in a liquid sample of sulfur trioxide, SO3 is london dispersion force.

What is the MOLAR heat of combustion of methane(CH₄) if 64.00g of methane are burned to heat 75.0 ml of water from 25.00°C to 95

melamori03 [73]

Answer:

-5.51 kJ/mol

Explanation:

Step 1: Calculate the heat required to heat the water.

We use the following expression.

$Q = c \times m \times \Delta T$

where,

c: specific heat capacity
m: mass
ΔT: change in the temperature

The average density of water is 1 g/mL, so 75.0 mL ≅ 75.0 g.

$Q = 4.184J/g.\°C \times 75.0g \times (95.00\°C - 25.00\°C) = 2.20 \times 10^{3} J = 2.20 kJ$

Step 2: Calculate the heat released by the methane

According to the law of conservation of energy, the sum of the heat released by the combustion of methane (Qc) and the heat absorbed by the water (Qw) is zero

Qc + Qw = 0

Qc = -Qw = -22.0 kJ

Step 3: Calculate the molar heat of combustion of methane.

The molar mass of methane is 16.04 g/mol. We use this data to find the molar heat of combustion of methane, considering that 22.0 kJ are released by the combustion of 64.00 g of methane.

$\frac{-22.0kJ}{64.00g} \times \frac{16.04g}{mol} = -5.51 kJ/mol$

ad-work [718]

Answer:

1.67mol/L

Explanation:

Data obtained from the question include:

Mole of solute (K2CO3) = 5.51 moles

Volume of solution = 3.30 L

Molarity =?

Molarity is simply the mole of solute per unit litre of the solution. It can be expressed mathematically as:

Molarity = mole of solute /Volume of solution

Molarity = 5.51 mol/3.30 L

Molarity = 1.67mol/L

Therefore, the molarity of K2CO3 is 1.67mol/L
