Use the reaction given below to solve the problem that follows: Calculate the mass in grams of aluminum oxide produced by the reaction of 15.0 g of aluminum metal. [ ]grams Al2O3

4 Al + 3 O2 --> 2 Al2O3

**Your answer should be written as XX. X

 28.4 g of aluminum oxide is produced by the reaction of 15.0 g of aluminum metal

Explanation:

To calculate the moles :

The balanced chemical equuation is:

According to stoichiometry :

4 moles of produce == 2 moles of

Thus 0.556 moles of will produce=  of

Mass of

Thus 28.4 g of aluminum oxide is produced by the reaction of 15.0 g of aluminum metal.

i just learnt this recently but i need to look through my notes again

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
