The chemical equation balancer can find coefficients to balance the chemical equation, determine the type of reaction that occurred, its word equation, the thermodynamics of the reaction, and provide the steps to balance it using both the inspection and algebraic methods covered earlier. You can also use it to double-check …
Write a balanced equation and indicate the type of reaction for iron(iii) oxide and carbon monoxide into iron and carbon dioxide. Metals react with oxygen gas to produce oxides with the general formula MxOy. Write a balanced chemical equation for the reaction of iron to yield iron(II) oxide.
The ore is found in vast quantities in the iron formation of the Michipicoten District, Ontario; the quantity around the Helen Mine is estimated at not less than 100 million tons; the ore is high in sulphur, owing to the presence of pyrite, and requires to be roasted to remove sulphur as well as to remove carbon dioxide.
