Neco 2024 Chemistry Question 2
Practice practical question 2 from the 2024 Neco Chemistry examination. This question covers Periodic Table .
A 1.20 g sample of an unknown metallic element (M) is placed in a sealed reaction tube and heated with excess chlorine gas at 25 °C. The reaction proceeds to completion forming a chloride of formula MCl\(_n\) (where \(n\) is an integer). After the reaction, the mass of the solid chloride obtained is 2.10 g. (a) Determine the value of \(n\) (the number of chlorine atoms combined with each metal atom). (b) Calculate the atomic mass of the metal M. (c) Using the periodic table, suggest a possible identity for the metal, giving its chemical symbol and atomic number.
