Complete and balance the precipitation reaction. Include physical states in your answer. CuCI2(aq)+Na2CO3(aq)
I assume you meant CuCl2(aq)
CuCl2(aq) + Na2CO3(aq) ==> CuCO3(s) + 2NaCl(aq)
To complete and balance the precipitation reaction between CuCl2(aq) and Na2CO3(aq), we need to determine the products formed and ensure that the number of each type of atom is the same on both sides of the reaction equation.
The balanced chemical equation for the precipitation reaction is as follows:
CuCl2(aq) + Na2CO3(aq) → CuCO3(s) + 2NaCl(aq)
In this reaction, CuCl2(aq) reacts with Na2CO3(aq), resulting in the formation of a precipitate (solid) Copper(II) carbonate (CuCO3) and soluble Sodium chloride (NaCl).
The physical states indicated in the balanced equation are:
- CuCl2(aq) represents copper(II) chloride in aqueous solution (aq).
- Na2CO3(aq) represents sodium carbonate in aqueous solution (aq).
- CuCO3(s) represents copper(II) carbonate as a solid (s).
- 2NaCl(aq) represents sodium chloride in aqueous solution (aq).
Remember to double-check the chemical equation and physical states with your teacher or textbook to ensure accuracy in your specific case.
To complete and balance the precipitation reaction between CuCl2 (copper(II) chloride) and Na2CO3 (sodium carbonate), we follow the steps below:
1. Write the correct chemical equation for the reaction:
CuCl2 (aq) + Na2CO3 (aq) → CuCO3 (s) + 2NaCl (aq)
2. Identify the products formed:
The reaction produces CuCO3 (copper(II) carbonate) as a solid precipitate and NaCl (sodium chloride) as a soluble salt in aqueous form.
3. Balance the equation:
To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides:
CuCl2 (aq) + Na2CO3 (aq) → CuCO3 (s) + 2NaCl (aq)
The equation now shows that the number of atoms is balanced for each element.
4. Include physical states:
To include physical states, we use the following abbreviations:
(aq) - aqueous, indicating the substance is dissolved in water
(s) - solid, indicating the substance is in solid form
The balanced and complete precipitation reaction with physical states is:
CuCl2 (aq) + Na2CO3 (aq) → CuCO3 (s) + 2NaCl (aq)
In this reaction, when copper(II) chloride and sodium carbonate are mixed together in an aqueous solution, a solid precipitate of copper(II) carbonate is formed, while sodium chloride remains in the solution.
