Igcse Model Questions Vol1 2025 Chemistry Question 27
Practice objective / multiple choice question 27 from the 2025 Igcse Model Questions Vol1 Chemistry examination.
A metal oxide with the formula \(M_2O_3\) is reduced by carbon at 1200 °C according to \(M_2O_3 + 3C \rightarrow 2M + 3CO\). The metal forms a +3 oxidation state, reacts with dilute \(HCl\) to give a soluble chloride that forms the complex \([M(H_2O)_6]^{3+}\). Its atomic mass is 55.85 u and its density is 7.87 g cm⁻³. If 10.0 g of the oxide is reduced completely, calculate the volume of metal obtained and identify the metal.
