Explanation / Answer

1. The reason to get a difference between experimental and predicted weight might be:

a) reaction didn´t complete correctly this might be because the reaction is very slow and takes some time to accomplish or need some temperature and you didn´t provide the conditions to get all the reaction completed

b) you might have lost some of the reactants when transferring them into other containers

c) some of the reactants might have formed some undesired products (according to the conditions)
