Answer:
2K(s) + F₂(g) —> 2KF(s)
Step-by-step explanation:
__K(_) + __F₂(g) —> __KF(_)
The above equation can be balance as follow:
K(s) + F₂(g) —> KF(s)
There are 2 atoms of F on the left side and 1 atom on the right side. It can be balance by writing 2 before KF as shown below:
K(s) + F₂(g) —> 2KF(s)
There are 2 atoms of K on the right side and 1 atom on the left side. It can be balance by writing 2 before K as shown below:
2K(s) + F₂(g) —> 2KF(s)
Now, the equation is balanced.
