balance the entire chemical reaction using an atom inventory. remember to balance each element in the reaction.\n\nagi + na₂s → ag₂s + nai\n\nwhen the equation is balanced, what is the coefficient of silver iodide, agi?
Answer
Explanation:
Step1: Count initial atoms
On left - hand side: 1 Ag, 1 I, 2 Na, 1 S. On right - hand side: 2 Ag, 1 S, 1 Na, 1 I.
Step2: Balance Ag atoms
To balance Ag atoms, we need 2 AgI on the left - hand side since there are 2 Ag atoms in $Ag_2S$ on the right - hand side. The equation becomes $2AgI+Na_2S\rightarrow Ag_2S + NaI$.
Step3: Balance Na and I atoms
Now, with 2 AgI, we have 2 I atoms on the left. To balance I and Na atoms, we need 2 NaI on the right. The balanced equation is $2AgI + Na_2S\rightarrow Ag_2S+2NaI$.
Answer:
