In addition to the structure below, how many other resonance forms are needed to correctly describe the symmetry of the carbonate anion, (CO32- ) ? (Consider only resonance contributors that have an octet at C and formal charges that do not exceed +1.)

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 :

the awnser is group 12

gas

explanation:

smoke is the matter of a gas
