Answer 2

Answer:

1. The chemical equation for the reaction between iron and dilute sulphuric acid can be written as: Fe+H2SO4(dil)→FeSO4+H2.
2. Ethane undergoes hydrocarbon combustion, combining with oxygen to form carbon dioxide. The balanced chemical equation for the complete combustion of ethane is: 2 (C2H6) + 7 (O2) → 4(CO2) + 6(H2O) + Heat Energy (Enthalpy) , it is Combustion Reaction.
3. 2FeBr3 + 6H2SO4 → Fe2(SO4)3 + 3Br2 + 3SO2 + 6H2O. Iron(III) bromide react with sulfuric acid to produce iron(III) sulfate, bromine, sulfur dioxide and water. Sulfuric acid - concentrated solution.
4. The reactions of iodic acid with iodine in 96% sulfuric acid produce (IO)HSO4, I3+ and I5+, just like in the 100% acid. This reaction produces also I2O which is not formed in the pure acid. The equilibrium constants of the reactions producing these compounds are determined.
5. So, 3 aluminum reacts with 3 molecules of sulphate. When barium chloride reacts with aluminum sulphate it gives aluminum chloride and barium sulphate as a product. Barium sulphate is represented as BaSO4 barium has oxidation state and sulphate has oxidation state. Therefore 1 barium combines with 1 Sulphur.
6. Problem: Potassium hydroxide and phosphoric acid react to form potassium phosphate and water according to the equation. 3KOH(aq) + H3PO4(aq) → K3PO4(aq) + 3H2O(l)Determine the starting mass of each reactant if 58.5 g of K 3PO4 is produced and 86.8 g of H3PO4 remains unreacted.
7. Lead nitrate | Pb(NO3)2 - PubChem.
8. Aluminium react with sodium hydroxide and water to produce sodium tetrahydroxoaluminate and hydrogen. 2Al + 2NaOH + 6H2O → 2Na[Al(OH)4] + 3H2. The reaction of Aluminium with Sodium Hydroxide is a Displacement reaction (where one element is more reactive than the other and displaces it in a reaction). it is Sodium hydroxide and aluminum
9. Ammonium chloride reacts with a strong base, like sodium hydroxide, to release ammonia gas: NH4Cl + NaOH → NH3 + NaCl + H2O. ... A 5% by weight solution of ammonium chloride in water has a pH in the range 4.6 to 6.0.
10. The reaction between Lead Nitrate and Potassium Iodide is an example of______ ... Lead nitrate reacts with Potassium iodide to form Lead iodide and Potassium nitrate. Pb(NO3)2 + 2KI → PbI2 + 2KNO3. The above reaction is also an example of double displacement reaction.
