The line AB has equation 5x + 3y + 3 = 0 and it intersects the line with equation 3x - 2y + 17 = 0 at the point B. Find the coordinates of B.

Two straight lines can intersect at only one point. To identify the point at which the lines cross, we make a simultaneous equation, and solve x and y from here, by firstly writing one equation on top of the...

Describe briefly how you would show that manganese(II) ions catalyse the reaction between manganate(VII) ions and ethanedioate ions, in dilute sulphuric acid.

Mix the reagents and record the time taken for a specific observation, e.g. disappearance of colour which is characteristic for this chemical reaction. We repeat this step and add more manganese(II) ions; a ...
