Consider the following chemical reaction: Sb2O3 +3C →2Sb+3CO

Determine the mass of antimony produced when 0.42 grams of antimony (Sb) oxide reacts with carbon ( C

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.

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
