Which of the following describes a pattern?
A. A record snowfall in January of one year
B. A solar eclipse that happens every 18 months
C. A tornado that is worse than any before it
D. The average height of a Sequoia tree

A. A record snowfall in January of one year.

I think it would be B. A solar eclipse that happens every 18 months

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 :

b.

the accuracy of the data.
