For each Mass of the following below, predict B for big, S for small, N for not effect base on a) to e):

a) the crucible, lid and products were warm when weighted

b) The Beryllium end up Beo (mass metal sample was correctly determined)

c) Some unreacted Mg remained in final product

d) Some products come off on student's fingers while carrying the crucible, lid, and its contents to the balanced room.

e)Some MgN2 react with carbon monoxide to form MgO and N2 and C. Carbon gave product a gray color.

Predict each of the followings from a) to e) (for each):

- Mass of crucible, lid and metal

-mass of empty crucible and lid

- Mass of metal sample

- Mass of crucible, lid, contents after heating

- Apparent mass of MgO

- Percentage yield

Answer rating: 100% (QA)

a Here the metal is Mg and the product is MgO but MgO is a solid substance hence it has no effect N ... View the full answer
