Explanation:
From the question we are told that
The reaction of cyclobutane and oxygen is
ΔH°f (kJ mol-1) : C4H8(g) = 27.7 ; CO2(g) = -393.5 ; H2O(g) = -241.8 ΔH° = kJ
Generally ΔH° for this reaction is mathematically represented as
=>
=>
Generally the total heat capacity of 4 mol of CO2(g) and 4 mol of H2O(g), using CCO2(g) = 37.1 J K-1 mol-1 and CH2O(g) = 33.6 J K-1 mol-1. C = J K-1 is mathematically represented as
=>
=>
From the question the initial temperature of reactant is
Generally the enthalpy change() of the reaction is mathematically represented as
=>
=>
<u>Explanation:</u>
Phosphorus and oxygen atoms are considered as non-metals and two non-metals usually form covalent bonds.
A covalent bond is formed when sharing of electrons takes place between the atoms forming a bond.
The nomenclature of a covalent compound is given by:
- The less electronegative element is written first.
- The more electronegative element is written then, and a suffix is added with it. The suffix added is '-ide'.
- If atoms of an element is greater than 1, then prefixes are added which are 'mono' for 1 atom, 'di' for 2 atoms, 'tri' for 3 atoms and so on..
From the two atoms, less electronegative atom is phosphorus and thus, is written first.
Naming of the given compound are as follows:
1. = The name given to this compound is tetraphosphorus heptoxide
2. = The name given to this compound is diphosphorus pentoxide
3. = The name given to this compound is diphosphorus tetroxide
4. = The name given to this compound is phosphorus monoxide
