Answer:
XCl₂ + 2AgNO₃ —> X(NO₃)₂ + 2AgCl
The coefficients are: 1, 2, 1, 2
Step-by-step explanation:
XCl₂ + AgNO₃ —> X(NO₃)₂ + AgCl
The equation can be balance as follow:
XCl₂ + AgNO₃ —> X(NO₃)₂ + AgCl
There are 2 atoms of Cl on the left side and 1 atom on the right side. It can be balance by writing 2 before AgCl as shown below:
XCl₂ + AgNO₃ —> X(NO₃)₂ + 2AgCl
There are 2 atoms of Ag on the right side and 1 atom on the left side. It can be balance by writing 2 before AgNO₃ as shown below:
XCl₂ + 2AgNO₃ —> X(NO₃)₂ + 2AgCl
Now, the equation is balanced.
The coefficients are: 1, 2, 1, 2
