Identify the sample and analyte in each of the scenarios.(a) Determination of the lead content in paint. lead paint
(b) Analysis of the nitrate content of soil near a local water source. soil nitrate
(c) Measurement of the citric acid found in a lime.
Identify the following as either sample or analyte.
(1) lead
(2) paint chips
(3) soil
(4) nitrate
(5) lime wedge
(6) citric acid
Answers
Answer:
a) Analyte: lead. Sample: paint.
b) Analyte: nitrate. Sample: soil.
c) Analyte: citric acid. Sample: Lime
1) Lead: Analyte.
2) Paint chips: Sample.
3) Soil: Sample.
4) Nitrate: Analyte.
5) Lime wedge: Sample.
6) Citric acid: Analyte.
Explanation:
A sample is a portion of material selected from a larger quantity of material while an analyte is the chemical of the system that will be analysed.
Thus:
a) Analyte is lead while you must take a sample of paint to analyze this lead.
b) Analyte is the nitrate while sample must be soil.
c) Analyte is citric acid and lime is the sample
1) Lead: Analyte.
2) Paint chips: Sample.
3) Soil: Sample.
4) Nitrate: Analyte.
5) Lime wedge: Sample.
6) Citric acid: Analyte.

Technically, there are an infinite number of possible amino acids, though we've found only 20 common ones that many organisms use and at least half a dozen obscure ones that specific organisms use. We focus only on the 20 common ones unless we're in a college level biochemistry course.
The three categories are nonpolar ones, polar ones, and charged ones. The nonpolar ones have non-polar side chains (no oxygens or nitrogens), the polar ones have polar side chains (most contain an OH group but no COOH group), the charged ones are either acidic or basic (has COOH group or a basic nitrogen).

The conjugate acidand base
and the term would be Amphoteric.
Conjugate acid-
What is Amphoteric?
Amphoteric is described as the term employed to denote a substance that possesses the characteristics of both an acid, as well as, a base.
Given equilibrium:
→
Therefore, the dissolution of in water leads to the display acid that is conjugate
and the conugate base
.
In case, the properties of both are reflected, it shows amphoteric nature.

Answer:
Conjugate acid- H^+
Conjugate base- SO4^2-
Terminology- Amphoteric
Explanation:
Consider the equilibrum shown below;
HSO4^-(aq)<-------> H^+(aq) + SO4^2-(aq)
Hence, When HSO4^- is dissolved in aqueous solution, it's conjugate acid is H^+ and it's conjugate base is SO4^2- as shown in the equation above.
If a substance behaves both as an acid and as a base, then the substance is Amphoteric in nature.

The element that has been a halogen from the given elements have been Chlorine. Thus, option A is correct.
Halogen has been given as the group of metallic compounds that have been consisted of the one valence electrons in their last orbitals.
The halogens have been the most reactive elements and belong to group 18 of the periodic table. From the given set of elements, the number of valence electrons in the following has been:
- Chlorine = 1 valence electron
- Oxygen = 6 valence electrons
- Carbon = 4 valence electrons
- Radon = 8 valence electrons
Since the element having 1 valence electron has been Chlorine. Thus, the element that has been a halogen from the given elements have been Chlorine. Thus, option A is correct.

Answer:
it’s electron configuration is 1s^2 2s^2 2p^4. To determine valence electrons, add the outermost s and p orbitals. In an oxygen atom, 8 electrons are present. Electron present in the first shell (n=1) 2n^2=2 (1)^2=2 (1)=2.
