Using the periodic table, what can you conclude about the classification of iodine?

Iodine is a nonmetal and is dull, brittle, poor conductor of heat and electricity, forms anions in aqueous solution, and is a solid at room temperature.

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 :

it means there are 3 atoms of oxygen
