Solubility tests are often used to help distinguish and identify ionic compounds (see forexample, Experiment 9). Solubility is sometimes also useful for the identification of organiccompounds. After referring to Appendix 1, suggest a method for distinguishing between ethanol and cyclohexane.

Water Solubility Test

Explanation:

Ethanol possess a polar -OH group which is capable of forming hydrogen bond in water. Thus making ethanol miscible with water and ultimately soluble.

Cyclohexane on the other hand is a non polar compound with no dipole-dipole interaction ability with water. This makes it insoluble in water

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 :

a polar bond is formed when electrons are shared unevenly between atoms
