It's important to recognise which elements are written with a subscript 2 and which are not. Take care to use the correct form in chemical equations involving these elements.

Using logarithms, we can express \(y = k{x^n}\) in the form of the equation of a straight line \(y = mx + c\). Shown below is a straight line graph when \({\log _{10}}y\) is plotted against ...
