Respuesta :
The reaction of the calcium metal with potassium chloride is a displacement reaction, which results in the formation of the calcium chloride, and potassium ions. This reaction can be written as follows in a balanced form:
[tex]Ca^{+}[/tex] (s) + 2KCl(aq) → Ca [tex]Cl_{2}[/tex] (s) + 2 [tex]K^{+}[/tex] (aq)
The equation now on the right and left side of the reaction are both balanced and equal. Hence, the correct answer is 'Option A'.
The balanced equation for the reaction between Calcium metal and potassium chloride solution to form calcium chloride and potassium ion is:
Ca(s) + 2KCl(aq) —> CaCl₂(s) + 2K⁺(aq)
The coefficients are: 1, 2, 1, 2
The correct answer to the question is Option A. 1, 2, 1, 2
The equation for the reaction between Calcium metal and potassium chloride solution to form calcium chloride and potassium ion can be written as follow:
Calcium => Ca
Potassium chloride => KCl
Calcium chloride => CaCl₂
Potassium ion => K⁺
Calcium + Potassium chloride —> Calcium chloride + Potassium ion
Ca(s) + KCl(aq) —> CaCl₂(s) + K⁺(aq)
The above equation can be balance as follow:
There are 2 atoms of Cl on the right side and 1 atom on the left side. It can be balance by writing 2 before KCl as shown below:
Ca(s) + 2KCl(aq) —> CaCl₂(s) + K⁺(aq)
There are 2 atoms K on the left side and 1 atom on the right side. It can be balance by writing 2 before K⁺ as shown below:
