a) Describe the nature of ionic bonding. b) State the electron configuration of the Ca (II) ion. c) Outlie why solid calcium is a good conductor of electricity.

a) Ionic bonding is the electrostatic attraction between oppositely charged ions (+ and -). [1]b) 1s22s22p63s23p6 [1]c) Metallic bonding occurs through delocalized electrons in solid calcium. Those electrons are the ones that can conduct electricity while they are mobile/free to move. [1]

Which are four factors affecting the rate of a chemical reaction and how do these affect the rate constant of the reaction?


Use the following information: [[[[2H2(g) + O2(g) → 2H2O(l) ∆H = −572 kJ mol−1]]]] [[[[2H2(g) + O2(g) → 2H2O(g) ∆H = −484 kJ mol−1]]]] to calculate the enthalpy change for the process: H2O(g) → H2O(l)


How can we determine the molecular and electron geometry of H2O?


0.120g of an ideal gas was introduced into a gas syringe. The volume occupied by the gas at a pressure of 1.02x10^5 Pa and temperature 20 degrees was 49.3 cm^3. Calculate the molar mass of the gas.
