The balanced equation below shows the products that are formed when pentane (C5H12) is combusted.C5H12 + 802 → 10CO2 + 6H20
What is the mole ratio of oxygen to pentane?

The density of the element in grams per cubic centimeter can be rewritten in kilograms per cubic meter as 11,300 kg/m³

What is the density of the element in kilograms per cubic meter?

Given the parameter:

The density of an element is 11.3 g/cm³

To convert the density from grams per cubic centimeter to kilograms per cubic meter, we can use the following conversion factors:

1 gram = 0.001 kilograms

1 cm³ = 1000000m³

Density in kg/m³ = Density in g/cm³ × (0.001 kg/g) × ( 1000000 m³/cm³)

Density in kg/m³ = 1000

Now, given the density of the element as 11.3 g/cm³:

Density in kg/m³ = 11.3 × 1000

Density in kg/m³ = 11,300 kg/m³

Therefore, the density of the element is approximately 11,300 kg/m³.

Explanation:

Aromatic compounds undergo electrophilic substitution reaction which passes through a positively charged intermediate to yield the product.

Substituted benzenes may be more or less reactive towards electrophilic aromatic substitution than benzene molecule depending on the nature of the substituent.

Certain substituents increase the ease of reaction of benzene towards aromatic substitution.

If we look at the compounds closely, we will notice that toluene reacts readily with CH3Cl / AlCl3. This is because, the methyl group is electron donating hence it stabilizes the positively charged intermediate produced in the reaction.

Carbonyl compounds are electron withdrawing substituents hence they decrease the magnitude of the positive charge and hence decrease the rate of electrophilic aromatic substitution.
