Question 1. considering the reaction of the decomposition of n2o5 to form the products no2 and o2, calculate the average reaction rate if at 0.00s the concentration of n2o5 was 1.00 m and at 4.00s it decreases to 0.987 m?
2 n2o5 4 no2 + o2
4.97 × 10-1 mol/(l × s)
7.27 × 10-2 mol/(l × s)
6.50 × 10-3 mol/(l × s)
3.25 × 10-3 mol/(l × s)

In this chemical reaction, 325 grams of barium (ba) react completely. how many moles of lithium (li) are produced?

Ascientist measures the speed of sound in a monatomic gas to be 449 m/s at 20∘c. what is the molar mass of this gas?

How do cfcs cause ozone depletion? how do cfcs cause ozone depletion? ultraviolet radiation breaks down cfcs, molecules containing chlorine. chlorine then breaks one oxygen atom away from ozone, leaving behind a paired oxygen molecule. ultraviolet radiation breaks down cfcs, molecules containing chlorine. chlorine then breaks two oxygen atoms away from ozone, leaving behind a paired oxygen molecule. ultraviolet radiation creates cfcs, molecules containing chlorine. chlorine then breaks two oxygen atoms away from ozone, leaving behind a paired oxygen molecule. ultraviolet radiation creates cfcs, molecules containing chlorine. chlorine then breaks one oxygen atom away from ozone, leaving behind a paired oxygen molecule.
