inorganic

Question 1

thermal decomposition

Answer 1

Thermal decomposition is the breaking down of a compound using heat.

Question 2

charge density

Answer 2

Charge density is a measure of charge over size of ion (so a small, highly charged ion would have a high charge density)

Question 3

polarising power

Answer 3

Polarising power is the ability of a cation to polarise an anion. More charge dense cations have greater polarising power.

Question 4

polarisability

Answer 4

Polarisability is how much an anion is able to be polarised by a cation. Larger, more negatively charged ions are more polarisable (eg. As3- would be more polarisable than F-).

Question 5

electronegativity

Answer 5

Electronegativity is the ability of an element to attract a pair of electrons in a covalent bond.

Question 6

displacement reaction

Answer 6

A displacement reaction is one in which a more reactive element displaces a less reactive element from a compound (swapping places with it).

Question 7

precipitate

Answer 7

A precipitate is a solid formed from the reaction between two solutions.
