What is the test that determines the amount and purity of a given chemical in a preparation in the laboratory?
The test that determines the amount and purity of a given chemical in a preparation is called a quantitative analysis. This involves techniques such as titration, spectroscopy, chromatography, and gravimetric analysis to measure the quantity of the chemical present, as well as assess its purity.
Which procedure would be part of a laboratory investigation designed to determine of a specific nutrient is present in a food?
The procedure would involve testing the food sample for the presence of the specific nutrient using a chemical test. This may involve extracting the nutrient from the food sample, using specific reagents to detect the nutrient, and comparing the results against a standard or control sample.
How do you determine the chemical make up on the molecular level of a piece of corn?
The chemical makeup of a piece of corn can be determined by conducting chemical analysis techniques such as chromatography, mass spectrometry, and nuclear magnetic resonance (NMR) spectroscopy. These techniques help identify the specific molecules present in the corn, such as carbohydrates, proteins, lipids, vitamins, and minerals. Additionally, elemental analysis can provide information on the elemental composition of the corn.
To determine the formula of a new substance one of the first steps is to find?
The first step to determine the formula of a new substance is to determine the elements present in the substance through experimentation or analysis. Once the elements are identified, the next step is to determine the ratio of atoms of each element in the substance to establish the chemical formula.
What is present after a chemical reaction?
That depends on the chemicals present before the chemical reaction and sometimes the conditions under which the chemical reaction occurred.
What indicates the chemical makeup of a substance by showing how many of each kind of atoms is present in a molecule?
That would be called chemical analysis. If you just want to know what the compound is, that is a qualitative analysis, and if you want to know exactly how much of it you have, that is a quantitative analysis.
When would you choose a wet chemical analysis procedure over an instrumental analysis procedure?
A wet chemical analysis procedure, such as a titration, may be chosen when the analyte can be easily characterized by a chemical reaction with a specific reagent. This method is often used when the analyte is present in high concentrations and when accuracy is more important than speed. Instrumental analysis procedures are usually favored when high sensitivity, precision, and speed are required, and when the analyte is present in trace amounts.
Where can quantitative analysis be used in chemistry?
Forensics. QA is used to find what sort of chemical or compound is present in an unknown substance.

What nutrient is present in kabbab?
sausages
What is the nutrient present in glucose?
carbohydrates
Why has salinity been based on the amount of chlorine present in the oceans?
-Due to the principle of constant proportions -It can be accurately measured with a simple chemical analysis
What kind of molecule performs chemical digestion in the stomach?
Protein is the only nutrient broken down in the stomach. This is because only protease enzymes are present in the stomach acid.
Which procedure would be part of a laboratory investigation designed to determine of a specific nutrient is present in a food?
The procedure would involve testing the food sample for the presence of the specific nutrient using a chemical test. This may involve extracting the nutrient from the food sample, using specific reagents to detect the nutrient, and comparing the results against a standard or control sample.
What has the author F Twyman written?
F. Twyman has written: 'On the development and present position of chemical analysis by emission spectra' 'An East Kent family'
Which nutrient is present in the substance amylase?
Amylase is an enzyme that catalyses the breakdown of starch into sugars.It is not a nutrient.
