Things I Didn't Remember

Question 1

How many carbons is each carbon atom in fullerene bonded to?

Answer 1

3

Question 2

What types of bonding exist in fullerene?

Answer 2

Covalent and London dispersion

Question 3

With regards to topic 5, formation reactions show the enthalpy change when one mole of a substance is produced from its elements in their standard states. Should you alter the coefficient or subscript of diatomic reactants in this case?

Answer 3

Coefficients; for example 0.5 O2

Question 4

Outline the conditions of a chemical reaction in equilibrium

Answer 4

The forward and reverse reactions occur at the same rate and the concentration of the products and reactants are constant

Question 5

To which side does the equilibrium constant shift when pressure increases and why?

Answer 5

To the side with fewer GAS molecules or moles of GAS because it wants to minimize the collisions of particles

Question 6

What effect does a catalyst have on the position of equilibrium and why?

Answer 6

It doesn’t affect it because it increases the rate of both forward and reverse reactions

Question 7

Define electronegativity

Answer 7

the ability of an atom to attract a bonded pair of electrons

Question 8

Define average bond enthalpy

Answer 8

the energy required to break one mole of a covalent bond in a gaseous melocule
