Iron is extracted from iron ore. Part of the process involves reduction of the ore with carbon monoxide. Iron ore contains iron oxide ($Fe_2O_3$). How would you write a balanced equation for the reaction of iron oxide with carbon monoxide?
And this is the effectual chemical reaction of our civilization. If you ever have a chance to tour a blast furnace (and most are in China and India now) do...

How do i calculate the number of moles of magnesium, chlorine, and oxygen atoms in 7.70 moles of magnesium perchlorate, $"Mg"("ClO"_4)_2$. Express the number of moles of Mg, Cl, and O atoms numerically, separated by commas. moles of Mg, Cl, O =?
$1 "mol" " Mg"("ClO"_4)_2$ contains :- $color(red)(1 "mol Mg atoms")$ $color(blue)(2 "mol Cl atoms"$ $color(green)(8 "mol O atoms"$ To find no. of moles of each element,...

How many moles of iron (Fe) is $5.98 times 10^24$ atoms of iron?
Well, one mole specifies $6.022xx10^23$ individual particles....and so we take the quotient..... $(5.98xx10^24*"iron atoms")/(6.022xx10^23*"iron atoms"*mol^-1)=??*mol$.. What is the mass of the quantity of atoms?

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...

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 rusts when exposed to oxygen. Iron(II) is produced in the reaction. How many moles of oxygen oxide will react with 2.4 mol of iron in the rusting reaction?
$Fe(s) + 1/2O_2 rarr FeO(s)$ 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...

One mole of iron III sulfate, $Fe_2(SO_4)_3$, contains how many moles of $SO_4^-2$ ions? How many moles of O atoms?
Here, we use as we would use any other collective number: a dozen eggs; a Bakers' dozen; a Botany Bay dozen. Of course, the mole specifies a much larger quantity,...

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...

Solid iron a specific heat of 0.444 J/g°C. If 75 calories of energy were removed from a piece of iron, and the temperature of the iron went from 21.4°C to -25.2°C, what was the mass of the iron?
When you look at the big picture, what you have is heat flowing out of solid iron and cooling it down. So, you have to use the heat flow equation:...
