Names four types of chemical reaction?

Single replacement ex: 2K + 2HCl --> 2KCl + H2 Double replacement ex: Na2SO4 + 2CaCO3 --> Na2CO3 + CaSO4 Combustion ex: H2CO3 --> H2O + CO2 Synthesis ex: 2Fe + O2 --> 2FeO


An alternative method for preparing pure iron from fe2o3 is by reaction with carbon monoxide fe2o3 plus co fe plus CO2 unbalanced a balance the equation use the lowest possible coefficients?

The balanced equation for the reaction is: 3Fe2O3 + 3CO → 2Fe + 3CO2. This equation ensures that the number of atoms for each element is the same on both sides of the equation.


Which of the following reactions is a synthesis reaction?

synthesis reaction occurs when elements or compounds combine to form a new, more complex compound. a few examples of this in its form is: 2F+O2= 2FEO 6H+O2= Ag5o


Chemistry What type of chemical reaction is involved in the corrosion of iron?

the corrosion elements are CO2 and H2O. but rust is ferric oxide. so simple equation is, 2Fe + 3O2 = Fe2O3 but oxygen directly does not react with iron actual mechanism is, CO2 + H2O = H2CO3 2Fe + H2CO3 = Fe(HCO3)2 + H2 2H2 + O2 = 2H2O 2Fe(HCO3)2 = Fe2(CO3)3 + CO2 + 2H2O Fe2(CO3)3 = Fe2O3 + 3CO2


If 1.00 kg of Fe2O3 completely reacts with CO the volume of CO2 released at STP will be?

There are several different possible reactions of Fe2O3 with CO, depending on temperature and ratio of reactants. The simplest is probably Fe2O3 + CO ==>2FeO + CO21.00 Kg x 1000 g/Kg x 1 mole Fe2O3/160 g = 6.25 moles Fe2O3 moles CO2 produced = 6.25 moles CO2 Volume CO2 at STP = 6.25 moles x 22.4 L/mole = 140 Liters


What kind of chemical reaction is this CaCO3 - CaO CO2?

This is a decomposition reaction where calcium carbonate (CaCO3) breaks down into calcium oxide (CaO) and carbon dioxide (CO2) upon heating.


What kind of reaction is represented by CH4 plus 2O2 --CO2 plus 2 H2O?

The reaction you've provided is a combustion reaction. In this reaction, methane (CH4) reacts with oxygen (O2) to form carbon dioxide (CO2) and water (H2O) as products.


What kind of reaction is represented here caco3 plus h2so4 caso4 h2 co2?

The reaction you provided is a double displacement reaction. In this reaction, calcium carbonate (CaCO3) reacts with sulfuric acid (H2SO4) to produce calcium sulfate (CaSO4), water (H2), and carbon dioxide (CO2).


What is the balanced equation for Fe2 plus O3 plus C equals CO2 plus Fe?

Your unbalanced equation is _Al + _Cr2O3 ----> _Cr + _Al2O3. Multiply aluminum (Al) and chromium (Cr) ratio by 2, so each side has the same amount of each element. As a result, the equation 2Al + Cr2O3 -----> 2Cr + Al2O3 is balanced. This is a single replacement reaction.


What is the balanced chemical reaction of CO2---CO O2?

This reaction is:2 CO2 = 2 CO + O2


What kind of chemical reaction is represented by the equation CaC03 Ca0 C02?

The equation CaCO3 -> CaO + CO2 is an example of a decomposition reaction.


Why does the carbon dioxide vary with time during an acid and carbonate reaction?

The reaction of an acid with a carbonate produces CO2 gas. Initially, there is no CO2, but as the reaction proceeds, CO2 is produced and the level of CO2 increases. When one or both of the reactants runs out (is limiting), the production of CO2 ceases. The general reaction looks like this: 2H^+ + CO3^2- ---> H2CO3 ---> CO2(g) + H2O
