Neco 2024 Chemistry Question 2
Practice objective / multiple choice question 2 from the 2024 Neco Chemistry examination.
Ten point zero grams of nitrogen gas reacts with excess oxygen to give nitrogen dioxide according to \(\mathrm{N_2 + 2\,O_2 \rightarrow 2\,NO_2}\). The nitrogen dioxide then reacts with water: \(\mathrm{3\,NO_2 + H_2O \rightarrow 2\,HNO_3 + NO}\). Assuming an overall 80 % yield for \(\mathrm{HNO_3}\) based on the amount of nitrogen originally present, calculate the mass of \(\mathrm{HNO_3}\) obtained (in grams, three significant figures).
