Bayer process. The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef Bayer. Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al 2 O 3 ), the rest being a mixture of silica, various iron oxides, and titanium dioxide. [1]
In this explainer, we will learn how to describe the extraction of iron from its ore in the blast furnace. Extraction of iron is arguably one of the most important industrial processes on
4 × 1 = 4. 2 × 2 = 4. 4 = 4, yes. O. 2 × 2 = 4. (1 × 2) + (2 × 1) = 4. 4 = 4, yes. A balanced chemical equation often may be derived from a qualitative description of some chemical reaction by a fairly simple approach
Chemical equations have reactants on the left, an arrow that is read as "yields", and the products on the right. 7.3: Chemical Equations is shared under a license and was authored, remixed, and/or curated by LibreTexts. A chemical reaction is the process in which one or more substances are changed into one or more new substances.
The key features of a chemical equation are pointed out here: Reactants are the substances we start with. They are written on the left side of the arrow. Products are the substances that are created. They are written on the right side of the arrow. The arrow indicates that a chemical change has occurred.
The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the

There are twice as many chloride ions in the reactants as there are in the products. Place a 2 in front of the NaCl in order to balance the chloride ions. Pb(NO 3) 2(aq) + 2 _ NaCl(aq) → NaNO 3(aq) + PbCl 2(s) 1 Pb atom on both reactant and product sides. 2 Na atoms on reactant side, 1 Na atom on product side.
General chemical structure of food fats (triglyceride). R 1 , R 2 and R 3 are alkyl groups (approx. 20%) or alkenyl groups (approx. 80%). Olive oil is composed mainly of the mixed triglyceride esters of oleic acid , linoleic acid , palmitic acid and of other fatty acids , [97] [98] along with traces of squalene (up to 0.7%) and sterols (about 0.2% phytosterol and
The representation of a chemical reaction in the form of symbols (substances) is known as chemical equation. A chemical equation consists of reactants, products and an arrow showing the direction of reaction. The equation in which number of atoms of all the molecules is equal on both sides of the equation is known as balanced chemical equation.
The individual reactions are indicated in Figure 23.3.2 23.3. 2. The iron oxides are reduced in the upper region of the furnace. In the middle region, limestone (calcium carbonate) decomposes, and the resulting calcium
The final chemical step in producing ethanol from the starch is fermentation. The chemical reaction of fermentation is where 1 mole of glucose yields 2 moles of ethanol and 2 moles of carbon dioxide. The reaction is shown in
The iron concentrate grade β was obtained by the chemical element analysis, and the recovery ϕ was calculated by equation . (1) ϕ = β ⋅ γ α × 100 % Where β is the Fe grade of the iron concentrate, α is the Fe grade of the raw material, γ is the yield of the iron concentrate, and ϕ is the iron recovery of the iron concentrate.
1. Using the chemical equation from page 1 as an example, write (or type) the balanced equation for the formation of iron(II) oxide, FeO, from the elements of iron, Fe, and oxygen, O 2 .Include states of matter. 2. If the amount of product made ( FeO) was determined to contain 4.82 moles of iron, how many moles of oxygen are expected to be in the product?
Perhaps the most useful feature of thermochemical equations is that they can be combined to determine ΔH m values for other chemical reactions. For example, iron forms several oxides, including iron(II) oxide or wüstite (FeO), iron(III) oxide or hematite (Fe 2 O 3 ), and finally, iron(II,III) oxide or magnetite (FeO·Fe 2 O 3 or Fe 3 O 4 ).
THE CHEMISTRY OF MILK. The principal constituents of milk are water, fat, proteins, lactose (milk sugar) and minerals (salts). Milk also contains trace amounts of other substances such as pigments, enzymes,
Chemical equations are an efficient way to describe chemical reactions. This module explains the shorthand notation used to express how atoms are rearranged to make new compounds during a chemical reaction. It shows how balanced chemical equations convey proportions of each reactant and product involved. The module traces the
Step 2: Count the number of each atom or polyatomic ion on both sides of the equation. Reactants 1Catom 4H ions 2Clatom Products 1Catom 1H ions 5Clatoms Reactants Products 1 C atom 1 C atom 4 H ions 1 H ions 2 Cl atom 5 Cl atoms. Step 3: W e find that both sides are already balanced with one carbon atom.
The reaction of the rusting of iron involves an increase in the oxidation state of iron, accompanied by a loss of electrons. Rust is mostly made up of two different oxides of iron that vary in the oxidation state of the iron atom. These oxides are: Iron (II) oxide or ferrous oxide. The oxidation state of iron in this compound is +2 and its
The chemical formula for rust is Fe2O3 and is commonly known as ferric oxide or iron oxide. The final product is a series of chemical reactions simplified below as- The rusting of the iron formula is simply 4Fe + 3O2 + 6H2O → 4Fe (OH)3.
DRI production. Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, i.e. without melting, as in the blast furnace. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal. Iron ore is used mostly in pellet and/or lumpy form.
The production of iron from its ore involves an oxidation-reduction reaction carried out in a blast furnace. Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue. The iron found in iron ores are found in the form of iron oxides. As a result of these impurities, iron must be first
AgNO 3 (aq) + 2KCl (aq) → AgCl (s) + KNO 3 (aq) Solution. By counting, we find two sodium atoms and two oxygen atoms in the reactants and four sodium atoms and two oxygen atoms in the products. This equation is not balanced. The reactants have one carbon atom, four hydrogen atoms, and four oxygen atoms.
