93.2 mL of a 2.03 M potassium fluoride (KF) solution

Marrrta [24]

Answer:

1.98 M

Explanation:

Given data

Initial volume (V₁): 93.2 mL

Initial concentration (C₁): 2.03 M

Volume of water added: 3.92 L

Step 1: Convert V₁ to liters

We will use the relationship 1 L = 1000 mL.

$93.2mL \times \frac{1L}{1000mL} = 0.0932 L$

Step 2: Calculate the final volume (V₂)

The final volume is the sum of the initial volume and the volume of water.

$V_2 = 0.0932L + 3.92 L = 4.01L$

Step 3: Calculate the final concentration (C₂)

We will use the dilution rule.

$C_1 \times V_1 = C_2 \times V_2\\C_2 = \frac{C_1 \times V_1}{V_2} = \frac{2.03 M \times 3.92L}{4.01L} = 1.98 M$

Use the bond dissociation energies of H2 (435 kJ/mol) and of a typical carbon–carbon bond (347 kJ/mol) to decide which bond is s

bogdanovich [222]

Answer:

H2 bond is stronger

Explanation:

In this question, we are trying to make a connection between bond dissociation energy and the strength of a bond.

First of all, we must know that any bond that is quite stable must have a large bond dissociation energy. This means that more energy is supplied in order to cleave the bond.

A high bond dissociation energy actually implies that a bond is of low energy and consequently stable.
