In the gaseous reaction I2 + Cl2 > 2ICl [ I2 ] changed from 0.400 M at the beginning of the reaction to 0.300 M after 4 min. Find the average of reaction rate by the unit mol /L. min

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

explanation:

2b2t

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
