Question

1. directions

drag and drop the correct answer choice to each answer blank. or, touch the answer choice followed by the answer blank.
2 agno₃ + fecl₂ ⟶ 2 agcl + ______
which product is needed to balance this equation and to follow the law of conservation of mass?
move the correct answer to the box.
fe(no₃)₂ 3 ag(no₃)₃ 2 ag(no₃)₄ fe₂cl₂ fe₃no₂

Explanation:

Step1: Analyze reactant atoms

Reactants: \(2\ce{AgNO3}\) has 2 Ag, 2 N, 6 O; \(\ce{FeCl2}\) has 1 Fe, 2 Cl. Total: 2 Ag, 1 Fe, 2 N, 6 O, 2 Cl.

Step2: Analyze product atoms (AgCl)

\(2\ce{AgCl}\) has 2 Ag, 2 Cl. Remaining: 1 Fe, 2 N, 6 O.

Step3: Find compound with remaining atoms

\(\ce{Fe(NO3)2}\) has 1 Fe, 2 N, 6 O. Matches remaining atoms.

Answer:

\(\ce{Fe(NO3)2}\)
