Write the molecular equation and the balanced equation for the following: Silver nitrate + copper strip. (a) When copper is heated in air, it reacts with the oxygen of air to form a black compound copper oxide. Having done this for both elements, they should find the ratio between the two by dividing them both by the smallest number. The students will need access to matches or lighters to light their Bunsen burners. Screen capture done with Camtasia Studio 4.0. Copper reacting with silver nitrate will produce copper (II) nitrate and silver. The outside of the envelope will react with oxygen in the air and will turn black. However, we can still assign oxidation states to the elements involved by treating them as if they were ionic (that is, as if all the bonding electrons were transferred to the more attractive element). Write a balanced equation for the reaction of cesium oxide with oxygen. This is a resource from thePractical Chemistry project, developed by the Nuffield Foundation and the Royal Society of Chemistry. 2Cu + O2 2CuO (b) When copper oxide formed in above reaction is heated in hydrogen, then copper oxide is reduced and brown copper metal is obtained.
