What else can I help you with?
What do you get from Fe plus CuO?
When iron (Fe) reacts with copper oxide (CuO), it forms iron oxide (Fe2O3) and copper (Cu). This reaction is a displacement reaction where the more reactive iron displaces copper from copper oxide.
What is the empirical formula of a substance that consists of 5.687 g copper and 1.305 g oxygen?
This the cuprous oxide, CuO.
Why should concentrated hcl help clean out a test tube soiled with cu2o?
The HCl will react with the CuO in a double replacement reaction given by the equation: 2HCl + CuO --> CuCl2 + H2O. Copper(II) chloride is water soluble, so it will clean right out.
Why CuO isnot dissolve in water?
Copper(II) oxide (CuO) does not dissolve in water because it is a basic oxide that reacts with water to form copper hydroxide (Cu(OH)2), which is insoluble in water. This reaction occurs slowly, preventing CuO from dissolving readily.
Is siderite soluble in water?
Siderite is not soluble in water.
What do you get from Fe plus CuO?
When iron (Fe) reacts with copper oxide (CuO), it forms iron oxide (Fe2O3) and copper (Cu). This reaction is a displacement reaction where the more reactive iron displaces copper from copper oxide.
What happens to ferric oxide solution when sodium sulfate is added?
Ferric oxide (Fe2O3) is not soluble in water.
Which metal oxides are insoluble in water and which are soluble?
Insoluble metal oxides generally include group II metal oxides like calcium oxide (CaO) and magnesium oxide (MgO). Soluble metal oxides often belong to group I metals like sodium oxide (Na2O) and potassium oxide (K2O), as well as transition metals like iron oxide (Fe2O3) and copper oxide (CuO).
Is Iron III oxide soluble?
Iron III oxide (Fe2O3) is insoluble in water and most common solvents, meaning it does not dissolve easily in these substances.
What metal oxides cannot be reduced to metal by hydrogen cuo ag2o fe2o3 mgo pbo?
CuO, Ag2O, and MgO cannot be reduced by hydrogen because they are already in their elemental form (copper, silver, and magnesium, respectively) and are stable. Fe2O3 (iron oxide) and PbO (lead oxide) can be reduced to their respective metals by hydrogen through a chemical reaction where hydrogen acts as a reducing agent.
What is the empirical formula of a substance that consists of 5.687 g copper and 1.305 g oxygen?
This the cuprous oxide, CuO.
What is an example of an oxide of a transition element?
Iron oxide (Fe2O3), also known as rust, is an example of an oxide of a transition element. It is a common compound that forms when iron reacts with oxygen in the presence of water or air.
Why should concentrated hcl help clean out a test tube soiled with cu2o?
The HCl will react with the CuO in a double replacement reaction given by the equation: 2HCl + CuO --> CuCl2 + H2O. Copper(II) chloride is water soluble, so it will clean right out.
Why CuO isnot dissolve in water?
Copper(II) oxide (CuO) does not dissolve in water because it is a basic oxide that reacts with water to form copper hydroxide (Cu(OH)2), which is insoluble in water. This reaction occurs slowly, preventing CuO from dissolving readily.
Is compounds containing metals always soluble in water?
No, compounds containing metals are not always soluble in water. The solubility of a metal compound in water depends on various factors such as the specific metal, the anion present in the compound, and the conditions such as temperature and pressure. Some metal compounds are soluble in water, while others are insoluble.
Is chlorine a water-soluble or fat-soluble?
Water soluble.
How are fat soluble and water soluble absorbed?
fat soluble vitamins are stored in our fat tissues and water soluble vitamins are soluble in water.
