Which describes the law of superposition used to find the relative age of fossils in rocks? A. Fossils were formed during a time when chemical processes operated differently.
B. Fossils of the same organism found at different locations formed in similar climates.
C. Fossils inside a layer of a rock are older than the surrounding rocks.
D. Fossils in bottom layers are older than fossils in top layers.

the answer is definitely c.

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 :
