2ag(s) + i₂(s) → 2agi(s)\nwhat is the correct ratio of particles of the substances in the chemical equation?\n2 moles ag: 1 mole i₂: 2 moles agi\n2 atoms ag: 1 molecule i₂: 2 formula units agi\n1 atom ag: 1 molecule i₂: 2 molecules agi\n2 molecules ag: 1 molecule i₂: 2 molecules agi
Answer
Explanation:
Step1: Identify particle - types in reactants and product
Silver (Ag) is an element and exists as atoms. Iodine ($I_2$) is a molecule. Silver iodide (AgI) is an ionic compound and exists as formula - units.
Step2: Analyze coefficients in the chemical equation
The balanced chemical equation is $2Ag(s)+I_2(s)\rightarrow2AgI(s)$. The coefficient of Ag is 2, meaning 2 atoms of Ag. The coefficient of $I_2$ is 1, meaning 1 molecule of $I_2$. The coefficient of AgI is 2, meaning 2 formula - units of AgI.
Answer:
2 atoms Ag:1 molecule $I_2$:2 formula units AgI
