Consider this reaction mechanism:
Step 1: Mo(CO)6% Mo(CO)3 + CO2
Step 2: Mo(CO)+ P(CH3)3 → Mo(CO) P(CH3)3
In terms of molecularity, Step 1 is
and Step 2 is
DONE

catya your not at all which answer i've seen you do this on another question!

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.

the objects have the same charge is correct.
