Answer:
FeCl3
Explanation:
Ferric chloride (FeCl3) is a chemical compound consisting of two elements--iron (Fe) and chlorine (Cl). "Fe" comes from the Latin word for iron which is ferrum. The small "3" next to Cl in the chemical formula means that for every atom of iron, there are three atoms of chlorine.

6. if 27.0 g of iron nail was used to react with oxygen gas, calculate the mass of ferric oxide produced in this reaction
The mass of Ferric oxide produced in this reaction : 38.57 g
Further explanationA reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
Reaction
4Fe+3O₂⇒2Fe₂O₃
mol of Fe(MW=55,845 g/mol) :
[tex]\tt \dfrac{27}{55,845}=0.483[/tex]
From the equation, mol ratio Fe : Fe₂O₃ = 4 : 2, so mol Fe₂O₃ :
[tex]\tt \dfrac{2}{4}\times 0.483=0.2415[/tex]
The mass of Fe₂O₃ (MW=159,69 g/mol) :

10. Ammonium sulfate added to ferric chloride
When ammonium sulfate is added to ferric chloride, it will react via double displacement. H acts as a metal in ammonium, which is weaker in reactivity compared to Fe. Therefore, Fe will replace ammonium and will form new compounds: ferric sulfate and ammonium chloride.

16. 40 Grams of iron is made to react with nitric acid, find the mass of ferric nitrite produced
Answer:
The mass of ferric nitrate, Fe(NO₃)₃ produced from the reaction given the data is 5792.44 g
Balanced equation
2Fe + 6HNO₃ –> 2Fe(NO₃)₃ + 3H₂
Molar mass of Fe = 56 g/mole
Mass of Fe from the balanced equation = 2 × 56 = 112 g
Molar mass of Fe(NO₃)₃ = 56 + 3[14 + (16×3)] = 242 g/mole
Mass of Fe(NO₃)₃ from the balanced equation = 2 × 242 = 484 g
SUMMARY
From the balanced equation above,
112 g of Fe reacted to produce 484 g of Fe(NO₃)₃
How to determine the mass of Fe(NO₃)₃ produced
From the balanced equation above,
112 g of Fe reacted to produce 484 g of Fe(NO₃)₃
Therefore,
1340.4 g of Fe will react to produce = (1340.4 × 484) / 112 = 5792.44 g of Fe(NO₃)₃
Thus, 5792.44 g of Fe(NO₃)₃ were obtained from the reaction

22. Bakit may mga Phenol na negative ang results sa Ferric Chloride Test?
Ang Ferric Chloride Test ay isang pangkaraniwang paraan para matukoy kung ang isang substance ay mayroong mga functional group na nagtatag ng isang phenol o hindi. Sa karaniwang mga kaso, ang mga substance na mayroong functional group na phenol ay magpapakita ng isang positibong resulta sa pagsusulit na ito, ngunit sa ilang mga kaso, maaaring magpakita ng isang negatibong resulta.
Ang isa sa mga posibleng dahilan kung bakit maaaring magpakita ng isang negatibong resulta ang isang phenol sa pagsusulit na ito ay dahil sa kakulangan ng sapat na halaga ng ferric chloride sa solusyon na ginagamit sa pagsusulit. Kung ang halaga ng ferric chloride sa solusyon ay hindi sapat, hindi ito magiging epektibo sa pagtukoy ng mga functional group na phenol sa isang substance.
Ang iba pang posibleng dahilan ay dahil sa kakulangan ng sapat na panahon para sa pagsusulit na ito upang magpakita ng isang positibong resulta. Kung hindi sapat ang panahon na ginugol sa pagsusulit, hindi ito magiging sapat upang matukoy nang tama kung mayroong functional group na phenol o hindi sa isang substance.
Kung ikaw ay nagtutulak ng isang negatibong resulta sa pagsusulit na ito, maaaring maging kapaki-pakinabang na suriin ang iyong solusyon ng ferric chloride at tiyakin na ito ay may sapat na halaga at panahon upang matukoy ng tama ang presensya ng mga functional group na phenol sa isang substance.

Greetings, mortal. I am Xiao, the Vigilant Yaksha and Conqueror of Demons. As one of the adepti who guards Liyue, I have seen and experienced much in my millennia of existence. I am not familiar with many human customs, but I am willing to assist you with your question or assignment to the best of my abilities. Please, do not hesitate to ask for my help.
Answer:
Ang Ferric Chloride Test ay isang pangkaraniwang pagsusulit na ginagamit upang masukat ang kakayahan ng isang compound na magpakita ng mga katangian ng isang phenol, na isang uri ng organic compound na may isang hydroxyl group na nakakonekta sa isang aromatic ring. Gayunpaman, hindi lahat ng mga compound na may mga katangian ng isang phenol ay magpakita ng positibong resulta sa pagsusulit na ito. Ang ilang mga compound na may mga katangian ng isang phenol ay hindi magpakita ng positibong resulta sa pagsusulit na ito dahil sa kanilang chemical structure o dahil sa mga impurities na nasa compound. Sa kasong ito, ang compound ay maaaring hindi magpakita ng positibong resulta sa Ferric Chloride Test dahil sa hindi tama o sapat na pagsusuri ng sample.
