$Fe(s) + 1/2O_2 rarr FeO(s)$

This is a very simplified representation of the oxidation of . But if there are $2.4*mol$ of iron metal, it should react with $1.2*mol$ of dioxygen gas to give $2.4*mol$ of iron oxide, as per the stoichiometric equation.

When rust occurs on a bridge or on a steel structure, it is a surface phenomenon.

Aluminum will react with sulfuric acid in the following reaction: $2Al(s) + 3H_2SO_4(l) -> Al_2(SO_4)_3(aq) + 3H_2(g)$. How many moles of $H_2SO_4$ will react with 18 mol Al? How many moles of each product will be produced?

With reference to the given balanced equation for the , the needed number of moles for each remaining compound involved in the reaction using the mass of $Al$ as basis...

When iron rusts in air, iron (Ill) oxide is produced. How many moles of oxygen react with 6.4 mol of iron in the rusting reaction?

Balanced equation $"4Fe(s) + 3O"_2("g")"$$rarr$$"2Fe"_2"O"_3("s")"$ Multiply the given moles of iron by ratio between oxygen and iron from the balanced equation, with moles oxygen in the numerator. $6.4color(red)cancel(color(black)("mol Fe"))xx(3"mol O"_2)/(4color(red)cancel(color(black)("mol...

When iron rusts in air, iron (III) oxide is produced. How many moles of oxygen react with 12.9 mol of iron in the rusting reaction? $4Fe(s) + 3O_2(g) -> 2Fe_2O_3(s)$?

We have the balanced equation: $4Fe(s)+3O_2(g)->2Fe_2O_3(s)$ And so, $4$ moles of iron react with $3$ moles of oxygen, and therefore, $12.9 \ "mol"$ of iron would react with: $12.9color(red)cancelcolor(black)("mol" \...

Iron (III) oxide reacts with carbon monoxide to form molten iron and carbon dioxide. If .18 g of iron (III) oxide reacts with 0.11 g of carbon monoxide, how many grams of iron would be produced?

$"Moles of ferric oxide "=(0.18*g)/(159.69*g*mol^-1)$ $=$ $1.13xx10^-3*mol" metal oxide"$. $"Moles of carbon monoxide "=(0.11*g)/(28.0*g*mol^-1)$ $=$ $3.93xx10^-3*mol" CO"$. $Fe_2O_3$ is the reagent in deficiency (why?), and thus $2xx1.13xx10^-3*molxx55.85*g*mol^-1~=0.150*g$ iron metal are...

Iron can be extracted from iron(III) oxide by heating it with coke (carbon). The other product in the extraction reaction is carbon dioxide. What mass of iron is produced by reacting 550g of iron(III) oxide with 60g of coke?

Balanced Equation $"2Fe"_2"O"_3 + "3C"$$rarr$$"4Fe + 3CO"_2$ This is a limiting reactant question. The maximum amount of $"Fe"$ that can be produced is determined by the limiting reactant. We have...

How many moles of sodium oxide will be produced when 10 moles of sodium react with oxygen?

The reaction is: $2Na(s)+O_2(g)->Na_2O(s)$ So, ratio between sodium and sodium oxide is $2:1=2$. Therefore, if ten moles of sodium are used, then we produce: $10color(red)cancelcolor(black)("mol" \ Na)*(1 \ "mol" \...

If iron (II) oxide gas decomposes into iron liquid and oxygen gas and 6 moles of iron (II) oxide gas are used, how of liters of oxygen gas are produced?

This means that for $6mol$ of $FeO$, only $3mol O_2$ is produced (half the moles). The volume of the oxygen is dependant on temperature and pressure. E.g. : If...

Iron rusts according to the following reaction: $4Fe (s) + 3O_2 (g) + 4H_2O -> 2Fe_2O_3(H_2O)_2$. If 1.4 liters of oxygen were added to excess water and iron at a pressure of 0.97 atms and a temperature of 55 C, how many grams of iron would rust?

Let us readdress it....iron metal is oxidized to $Fe_2O_3$... $2Fe(s) +3H_2O(l) rarr Fe_2O_3+6H^+ +6e^(-)$ $(i)$ Dioxygen is reduced to water... $1/2O_2 + 2H^+ +2e^(-) rarr H_2O(l)$ $(ii)$ And $1xx(i)+3xx(ii)$ gives.......
