2N2O5 (g) = 4NO2 (g) + O2(g) If the rate of decomposition of N2O5 at a particular instant in a reaction vessel is 4.2 x 10-7 M/s,

what is the rate of appearance of a) NO2 b) O2​

Which statement is true about this reaction? 14n+1h 15o it is a practical source of energy on earth. it occurs only outside the solar system. its product is heavier than each of its reactants. it shows the critical mass of an element.

Ineed ! i have no clue how to do this problem.

Covalent bonds generally form when the bonded elements have a difference in electronegativity less than 1.5. subtract the electronegativities for the following pairs of elements and predict whether they form a covalent bond. electronegativity difference of c and c: ionic covalent electronegativity difference of mg and cl: ionic covalent
