(a). Firstly, to work out the product, take 2Na⁺ + SO₂^- --> 2Na₂SO_4...

The easiest way to understand ionisation energy is to look at the equation for ionisation.For example, the ionisation of magnesium is shown by the following:Mg---> Mg⁺ + e^- The io...

The rate of achievement of equilibrium increases. This can be explained by collision theory. Because the temperature is increases the reactants have more energy and therefor the collisions between them be...

Electronegativity is the power of an atom to attract the electron density in a covalent bond towards itself. 
It depends on1.    The nuclear charge of the element2.    The distance between the nucleu...

First write out the equation given:Na + O₂ —> Na₂ONow count how many oxygen atoms are on the LHS of equation (2) and how many are on the RHS (1). This means you must put a 2 in f...
