What is the identity of a substance

Typically, the identity of a substance can be described by a: chemical name, for example, benzene; number, for example, EC number 200-753-7, and. chemical composition, for example, >99 % benzene and <1 % toluene.

Explanation:

Typically, the identity of a substance can be described as a: chemical name, for example, benzene chemical composition, for example, >99% benzene and <1% toluene. The composition is determined by chemical analysis.

explanation:

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
