The field of Analytical Chemistry allows you to determine what elements are in a substance. Qualitative analysis identifies which elements are present, while quantitative analysis determines the numerical amount or concentration of each of these elements. There are many ways to perform these tests.
You can show a substance containing an element by conducting experiments such as elemental analysis, spectroscopy (e.g., X-ray diffraction, NMR), and chemical reactions specific to that element. These experiments will help identify the presence of the element in the substance and provide evidence of its composition.

Which number in a chemical equation shows you the number of atoms?
The subscript number next to the chemical element symbol shows the number of atoms of that element in a chemical equation.
What do the lines on a phase diagram represent?
The lines on a phase diagram represent the boundaries between the different phases of a substance (such as solid, liquid, and gas). These lines show the conditions of temperature and pressure at which two phases can exist in equilibrium with each other.
Does the letter Q appear on the periodic table?
Technically yes it does, however it may not in the future. Currently the only element with a Q in its name is Ununquadium. It is the temporary name of a radioactive chemical element in the periodic table that has the temporary symbol Uuq and has the atomic number 114. Recent chemistry experiments have strongly indicated that element 114 appears to behave as the first superheavy element to show noble-gas-like properties due to relativistic effects. In appearance, it is likely a metal, probably silvery white or metallic gray in color.
Which element do all compounds contain?
Different compounds have different combintions of elements. However, chemistry can be divided into three divisions. #1 Organic ; Chemistry of CARBON containing compounds. #2 Inorganic ; The chemistry of all the other compounds NOT containing carbon. #3 Physical ; The calculations and equations, and physical states of substances.
How are subscripts used in a compound?
Subscripts in a compound are used to indicate the number of atoms present for each element in the compound. They show the ratio at which the elements are combined to form the compound. Each subscript number represents the number of atoms of the element that follows it.
What are the experiments that show that a substance in saliva can convert starch into reducing sugar?
Ptylan (or maybe it's ptylin), is the enzyme in saliva
Can you show me a experiment?
What did Dalton's experiments show
What can experiments can be used to show what?

3 reasons to show an element is a metal?
Its quite simple, three ways are that they conduct heat andelectricity are a malleable which means the ability of a substance to be hammered into shape!
Which number in a chemical equation shows you the number of atoms?
The subscript number next to the chemical element symbol shows the number of atoms of that element in a chemical equation.
How many experiments does it take to show that a hypothesis is false?
one
What did experiments of Hershey and chase show?

Are there any experiments to show that are a good conductors of electricity?
Yes, magnets
What are the release dates for EGG the Arts Show - 2000 Experiments in Theatre 2-11?
EGG the Arts Show - 2000 Experiments in Theatre 2-11 was released on: USA: 19 June 2001
Which scientist carried out experiments with light rays?
Newton did experiments using prisms to show that white light contained all colours of light.
What did francesco redi show by his experiments?
is that they had no moneey so they could notdo it becuse
What do scientists do when experiments show their hypotheses to be incorrect?
Hopefully the publish their negative results.
