Explanation: I took it on my test in k12 and I got it right. Why did you delete this..?

Answer :    It's B

Explanation:

The other girl in the comments got it right and her answer got deleted (sorry 2 u btw that was mean of him)

indium, and thallium have three electrons i think

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 :
