Neco Model Questions Vol1 2023 Chemistry Question 15
Practice objective / multiple choice question 15 from the 2023 Neco Model Questions Vol1 Chemistry examination.
A piece of copper metal weighing 5.00 g is placed in 0.10 mol of aqueous silver nitrate (AgNO₃). The reaction is: Cu(s) + 2 AgNO₃(aq) → Cu(NO₃)₂(aq) + 2 Ag(s). After completion, the silver precipitate is filtered, dried and weighed. (a) Calculate the mass of silver obtained. (b) Using the same amount of copper that actually reacted, determine the volume of hydrogen gas that would be liberated at STP if the copper instead reacted with excess dilute hydrochloric acid according to Cu + 2 HCl → CuCl₂ + H₂. Assume 100 % yield. Give the volume in litres to three significant figures.
