<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.

Answer:
No, the metal is not pure gold because density is equal to mass divided by volume and in this case we end up with about 15.3, making this metal less dense than gold.
Explanation:
Answer:Why is Dalton credited with proposing the first atomic theory if Democritus was talking about atoms almost 2,200 years earlier?
- Democritus' ideas were not supported by evidence
- Dalton's theory was the first scientific theory because it relied on scientific investigative processes.
- Dalton's theory was supported by evidence and repeated investigation.
Explanation: 1: Democritus' ideas were not supported by evidence
2: Dalton's theory was the first scientific theory because it relied on scientific investigative processes.
3: Dalton's theory was supported by evidence and repeated investigation.
A compound or a mixture.
If it is two or more elements are mixed, it is a mixture. If two or more elements are chemically reacted, it is a compound ( example FeS)
