A compound of mercury and oxygen is heated in order to decompose the compound. A 4.08 grams sample of mercury oxide upon heating
gives off oxygen gas. After heating the mass of mercury metal left behind was 3.78 grams. Calculate the empirical formula of the compound My and: 1 O2 to 2 Hg ratio but I don't know if it's correct and if so if I should write it as
2HgO ----> 2Hg + O2 or just 2Hg + O2
Please someone who understands help.
Explanation: Aluminium metal has a lower density than copper. So, for the same volume of metal used to build a model airplane, the aluminium plane would be very lightweight while that of copper would be heavy. The lightweight airplane will fly easily.
Make sure to convert all temperatures in Celsius to Kelvin by adding 273. Once you do that, multiply and divide accordingly to get the final answer of 825.5mL
