How does the chemical reaction between copper oxide and iron occur in water?

Fe+Cuo====Cu+Feo According to the strength of oxidation, 3-valent iron》bivalent iron》bivalent copper! Iron and copper oxide.

The displacement reaction takes place at high temperatures.

2Fe + 3Cuo == High Temperature == 3Cu + Fe2O3 This is the answer that my high school chemistry teacher told me.

Everything reacts at the same time.

The so-called sequential reaction is artificially determined for the convenience of understanding and calculation, while in the collision of microscopic particles, as long as the effective collision occurs, the reaction can occur, and it is not restricted by other ions, so it is a simultaneous reaction.

And we say that this first reaction, that later reaction, because the reaction products of the later reaction will react with the reactants that reacted first, and regenerate the reactants of the later reaction, so that it looks like there is a sequential reaction.

For example, Zn and Fe are put into CuSO4 solution at the same time, and the two react at the same time, Zn and Fe dissolve, forming ZnSO4 and FeSo4 respectively, but Zn will react with FeSo4 to form Fe, which means that Fe and CuSO4 have no reaction, so it is considered that Zn reacts first.

Iron and copper oxide, after the two react with sulfuric acid, they form Feso4 and Cuso4 respectively, iron cannot react with Cuso4 to form Cuo, and Cuo cannot react with Cuso4 to form back iron, so these two reactions cannot be regarded as which reacts first and which reacts later, that is, they react at the same time.

In this problem, because there is no phenomenon when adding iron sheets, it proves that Fe has replaced all the Cu in CuSO4 in the previous reaction, so the insoluble matter must contain Cu element. If the sulfuric acid is insufficient in the previous step, Fe and Cuo will not be sufficiently dissolved, and may contain precipitates of both.

Great landlord, if mine is helpful to you, please be sure to order"."Oh! Thank you for your cooperation!

It shouldn't react in the water.

Iron and copper oxide cannot react at room temperature because copper is more metallic active than iron. But at high temperatures, the two react, which is similarThermite reactionreactions. Reaction Equation:

3CuO+2Fe=High temperature=3Cu+Fe2O3.

Copper oxide is an inorganic substance with the chemical formula cuo. It is a black oxide of copper, slightly amphoteric and slightly hygroscopic. Insoluble in water, soluble in acid, stable to heat, decompose oxygen at high temperature. Copper oxide is mainly used in rayon, ceramics, glazes and enamels.

Batteries, petroleum desulfurizers, pesticides, and also for hydrogen production, catalysts, green glass, etc.

Iron. Iron is a metallic element with atomic number 26, iron elemental chemical formula: Fe, average relative atomic mass.

For. There are four stable isotopes of iron in nature, fe-54, fe-56, fe-57, and fe-58, which can be considered half-life without considering proton decay.

Infinitely long; There are also two other radioisotopes, fe-55 and fe-59, with half-lives of years and days, respectively.

Chloride-sensitive iron sentrich.

solution with copper hydroxide.

Chemical Equation ......

It is a reaction between salt and alkali, requiring the reactants to be soluble or at least slightly soluble in water, but copper hydroxide is a blue flocculent precipitate.

Iron and copper oxide reaction chemical formula: 2Fe + 3Cuo = = High temperature = 3Cu + Fe2O3. Copper oxide (cupricoxide), chemical formula Cuo.

It is a black oxide of copper, slightly amphoteric and slightly hygroscopic. Insoluble in water, soluble in acid, stable to heat, decompose oxygen at high temperature. Copper oxide is mainly used in the production of rayon, ceramics, glaze and enamel, batteries, petroleum desulfurizers, pesticides, and also for hydrogen production, catalysts, green glass, etc.

Iron is a metallic element with atomic number 26 and an elemental chemical formula for iron: Fe. Pure iron is white or silvery-white with a metallic luster.

Melting point 1538, boiling point 2750, soluble in strong acid and medium strong acid, insoluble in water. Iron has 0, +2, +3, +4, +5 and +6 valences, of which +2 and +3 are more common, and +4, +5 and +6 are rare.

There is no reaction between the two.

Copper oxide reaction with hydrochloric acid: Cuo + 2HCl = = CuCl2 + H2O Copper oxide reaction with sulfuric acid: Cuo + H2SO4 = = CuSO4 + H2O Iron oxide reaction with hydrochloric acid:

Fe2O3+6HCl==2FeCl3+2H2OReaction of iron oxide with sulfuric acid: Fe2O3+3H2SO4==Fe2(SO4)3+3H2O

Copper oxide cannot react with water. Copper oxide (cuo) is a black oxide of copper that is slightly hygroscopic, but insoluble in water, so it cannot react with water.

Copper oxide is insoluble in water, and metal oxides cannot react with water if they are insoluble in water. Metal oxides are 100% insoluble in water if they do not react with water. Because oxygen is very strong relative to all metals (including neutral ones), if the metal oxide ao is soluble in water, it is completely ionized into metal ions and oxygen ions, and the oxygen ions will react immediately with water to form hydroxide ions.

Therefore, it must be soluble and react, and it must be insoluble if it does not react.

Copper oxide ore is used to refine copper oxide, which is mostly produced in the Philippines, Pakistan and other regions, with a monthly volume of about 1,000 tons to 2,000 tons. Copper oxide (cuo) is a black oxide of copper. The most common ones on the market today are 98% copper oxide and copper oxide.

Uses of copper oxide:1used as analytical reagent (for nitrogen determination), oxidant, catalyst; It is used as a colorant in glass, enamel and ceramic industries, an anti-wrinkle agent for paints, and a polishing agent for optical glass.

2.It is used in the manufacture of dyes, organocatalyst supports, and copper compounds. It is also used in the rayon manufacturing industry and as a desulfurizer for grease.

It is used as a raw material for the manufacture of other copper salts, and is also a raw material for making artificial gemstones.
