*61. Sketch a reaction progress curve for the overall
reaction with the following mechanism:
2NO(g) → N2O2(g) (fast)
N2O2(g) + O2(g) → 2NO2(g) (slow)
What is the intermediate in this reaction?

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles
