Lewis structures are diagrams that show the bonding between
atoms of molecule and the lone pairs of electrons that may exist in the
molecule. Phosphoryl iodide is used in the preparation of organophosphorus
derivatives and phosphate esters. The Lewis structure of POI3 is:
Answer:
Zn(s) produces H₂ when is added to a strong acid solution
Explanation:
Look at this example:
2Zn (s) + 2HCl (aq) → 2ZnCl (aq) + H₂ (g)
It is a redox reaction, where the zinc is oxidized and the H, reducted.
Zn → Zn⁺ + 1e⁻
2H⁺ + 1e⁻ → H₂
You did not include the options but I can tell you the product ratio.
The product ratio is the mole ratio of the products of the reaction.
From the balanced chemical equation you have all the mole ratios:
The given equation is: 2 C6H5COOH + 15O2 --> 14 CO2 + 6H2O
The mole ratios are: 2 C6H5COOH: 15 O2: 14 CO2 : 6 H2O
The products are CO2 and H2O
Their mole ratio = 14 CO2 : 6 H2O
That can be expressed as:
14 mol CO2 7 mol CO2
----------------- = -----------------
6 mol H2O 3 mol H2O
It is also the same that:
6 mol H2O : 14 mol CO2
6 mol H2O 3 mol H2O
------------------ = -------------------
14 mol CO2 7 mol CO2
So, compare your options to the ratios show above and pick the proper ratio.
