The two steps are: the preparation of UF4 followed by the preparation of UF6.
In the enrichment process, uranium dioxide (UO2) is first converted into a gaseous form (UF6) by reacting it with hydrogen fluoride (HF). This displacement reaction allows for the separation of uranium isotopes based on their mass difference, which is crucial for increasing the concentration of the fissionable isotope U-235 for use in nuclear reactors.
The reaction between aqueous nitric acid (HNO3) and aqueous calcium hydroxide (Ca(OH)2) forms water (H2O) and aqueous calcium nitrate [Ca(NO3)2]. This is a double displacement reaction where the positive ions switch partners to form the products.
When aqueous sodium chloride and aqueous silver nitrate are mixed, a white precipitate of silver chloride is formed due to a double displacement reaction. The balanced chemical equation for the reaction is NaCl(aq) + AgNO3(aq) -> AgCl(s) + NaNO3(aq).
The reaction is a redox reaction where chlorine gas oxidizes iodide ions to form iodine molecules, while the chlorine is reduced to chloride ions. This is a single displacement reaction where chlorine displaces iodine in sodium iodide to form sodium chloride.
When solid zinc reacts with aqueous gold(III) nitrate, zinc displaces gold in the compound through a single displacement reaction. The products of the reaction are gold metal and aqueous zinc nitrate.

Example: double displacement reaction.
This type of reaction is called a double displacement reaction or a metathesis reaction. It involves the exchange of ions between two compounds to form two new compounds.
When aqueous calcium nitrate is added to aqueous lithium sulfate, a double displacement reaction occurs. The calcium and lithium ions switch places to form calcium sulfate and lithium nitrate. This reaction results in the formation of two new compounds: CaSO4 and LiNO3.
The chemical equation for the reaction between aqueous strontium sulfide (SrS) and aqueous copper sulfate (CuSO4) is: SrS + CuSO4 → SrSO4 + CuS Strontium sulfate (SrSO4) and copper sulfide (CuS) are the products of this double displacement reaction.
The reaction between bromine and aqueous strontium iodide is a double displacement reaction. Bromine replaces iodide in strontium iodide, forming strontium bromide and iodine. The balanced chemical equation is: Br2 + SrI2 --> SrBr2 + I2.
The reaction between aqueous nitric acid (HNO3) and aqueous calcium hydroxide (Ca(OH)2) forms water (H2O) and aqueous calcium nitrate [Ca(NO3)2]. This is a double displacement reaction where the positive ions switch partners to form the products.
The reaction between aqueous chlorine and sodium bromide solution results in the displacement of bromine by chlorine, forming sodium chloride and bromine gas as products. This is a redox reaction where chlorine is reduced and bromine is oxidized.
When aqueous sodium chloride and aqueous silver nitrate are mixed, a white precipitate of silver chloride is formed due to a double displacement reaction. The balanced chemical equation for the reaction is NaCl(aq) + AgNO3(aq) -> AgCl(s) + NaNO3(aq).
The reaction is a redox reaction where chlorine gas oxidizes iodide ions to form iodine molecules, while the chlorine is reduced to chloride ions. This is a single displacement reaction where chlorine displaces iodine in sodium iodide to form sodium chloride.
