The balanced equation for the syntheis of Iron (I) oxide is below: If 5.4 moles of Fe react with 4.7 moles of O2, what is the maximum amount of Fe2O3 (in moles) that can be produced? What is the limiting reactant?

a
3.1 moles of Fe2O3 is the maximum amount that can be produced. Oxygen is the limiting reactant.

b
2.7 moles of Fe2O3 is the maximum amount that can be produced. Iron is the limiting reactant.

c
7.1 moles of Fe2O3 is the maximum amount that can be produced. Oxygen is the limiting reactant.

d
10.8 moles of Fe2O3 is the maximum amount that can be produced. Iron is the limiting reactant.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.  

that's what i got you can count the number of atoms

since electrons are negative the answer is neagtaive

c. is the answer
