Is the following a redox reaction? Explain.<br> NH₃(aq) + HCl(aq) → NH₄Cl(aq)
jeyben [28]

The process is not a redox reaction.

The reaction between ammonia (NH_{3} )and hydrochloric acid (HCl) to produce ammonium chloride (NH_{4} Cl) has modified the oxidation number of no atom in the reactants. As a base, ammonia interacts easily with hydrochloric acid to produce ammonium chloride salt. A neutralization reaction between an acid and a base is what the described process is, and it is NOT a redox reaction.

A reaction is referred to as a redox reaction if two or more reactants belonging to a single reaction exchange one or more electrons, i.e., one reactant releases one or more additional electrons while the other obtains one or additional electrons. The reacted substance that releases electrons is oxidized and becomes a reducing substance. A reduced oxidizing agent is the reactant that accepts electrons.

<h3>What is spectrometric method?</h3>
  • A technique called spectrophotometry uses light intensity measurements as a beam of light travels through a sample solution to determine how much a chemical compound absorbs light.
  • Every chemical either absorbs or transmits light across a specific spectrum of wavelengths, according to the fundamental principle.
  • There are two main techniques used among the various forms of spectrophotometry:
  • ultraviolet-visible range spectrophotometry, which examines the reflectance of certain spectra,
  • and absorption spectrophotometry, which examines the absorption of radiation and particular spectra of light.
  • Applications of spectrophotometry are useful for determining how well gases, liquids, and solids transmit, reflect, and absorb light.

Using the balanced equation given below, calculate the number of moles of CaBr2 produced in the reaction of 5.0 moles of AlBr3.
allochka39001 [22]

Answer:

7.5 moles of CaBr2 are produced

Explanation:

Based on the equation:

2AlBr3 + 3CaO → Al2O3 + 3CaBr2

<em>2 moles of AlBr3 produce 3 moles of CaBr2 if CaO is in excess.</em>

<em />

Using this ratio: 2 moles AlBr3 / 3 moles CaBr2. 5 moles of AlBr3 produce:

5 moles AlBr3 * (3 moles CaBr2 / 2 moles AlBr3) =

<h3>7.5 moles of CaBr2 are produced</h3>
