This question tests your knowledge on; the properties of non-metal oxides in solution, the concept of equilibrium, pH.

Non-metal oxides such as (CO2, P4O10, SO2, etc) are acidic in solution. When l...

Using the substitutions a=2, b=7 and c=11 with the quadratic formula we get two values of x at 3.39 and 0.89.

Being able to find partial fractions is very useful for complex algebraic fractions that cannot be intergrated in their current form. Breaking it down into a sum of it's partial fractions gives two (or mo...
