Interpretation: It is given that, common nitrogen compounds having oxidation states ranging from
Concept introduction: Atoms lose or gain electrons to acquire stable state. Oxidation state is a number that is assigned to each element in a compound. This number describes the ability to loss or gain electrons.
To determine: The rationalization of range of oxidation state of common nitrogen compounds; some special properties for each substance given in Table

- In an experiment, 74.3 g of metallic copper was heated to 100.0°C and then quickly dropped into 200.0 mL of water in a calorimeter. The heat capacity of the calorimeter with the water was 875 J/°C. The initial temperature of the calorimeter was 27.5°C, and the final temperature after addition of the metal was 29.8°C. What is the value of the molar heat capacity of copper?arrow_forwardThe Haber-Bosch process permits the direct conversion of molecular nitrogen to ammonia, which can be used in large-scale fertilizer production. Given the balanced Haber-Bosch reaction and using the bond energies in the table below, estimate the enthalpy change associated with the reaction.
