Experiment for Diffusion? - correct answer 1) HCl placed at one end of the test tube, ammonia solution at the other. 2) Where they meet, a ring of Ammonium Chloride appears. 3) The diagram shows that the ammonia is closer to the ring, showing that ammonia must have travelled faster, showing it's a lighter gas. Experiment for Dilution? - correct answer 1) Put a coloured substance in a solvent e.g food colouring in water. 2) Over ...

ALGEBRA/MATRICES 2024 Motivation One important application for matrices is solving systems of linear equations. Some of the following definitions may be viewed as 'designed for solving system of linear equations'. Some terminologies Definition. (Matrix) A matrix (plural: matrices) is a rectangular array of numbers. A horizontal unit is a row, and a vertical unit is a column. The element in the th row and the th column is the th entry of the matrix. An (read 'm...
