What else can I help you with?
What type of objects would you do carbon dating on?
On an object with unknown age but more than halflife of C
Suppose you were given an unknown liquid and asked to determine if it was an element a compound or a mixture What would you do How would this help you find out what it was?
If I was given an unknown liquid and asked to determine if it was an element, a compound, or a mixture I would heat the unknown liquid up to see if any compounds separated from the unknown liquid. After that I would get a microscope and look to see if it is a pure element. Then I would get a Platelet separation machine and put the liquid in the machine to see if the liquid separated. Thats how I would determine if the an unknown liquid is an element, a compound, or a mixture.
What information could you use to determine the atomic number of an unknown element that has the mass number of 22?
To determine the atomic number of an unknown element with a mass number of 22, you would need to know the number of protons in the nucleus of the element. Since the mass number is the sum of protons and neutrons, subtracting the number of neutrons from the mass number would give you the atomic number. This is because the atomic number represents the number of protons in an element's nucleus.
Describe the laboratory procedures you would follow to determine whether an unknown element is a metal or nonmetal?
To determine whether an unknown element is a metal or nonmetal, you can perform a few simple laboratory tests. First, observe the element's physical properties such as its appearance, luster, and conductivity. Metals are typically shiny and good conductors of electricity. Next, perform a flame test by applying the element to a flame and observing the color produced. Different elements produce unique colors which can help identify if it is a metal or nonmetal. Finally, conduct a chemical reaction with an acid to see if the element reacts vigorously, which is a characteristic of metals.
What information could you use to determine the atomic number of unknown element that has a mass number of 22?
To determine the atomic number of an element with a mass number of 22, you would need the number of protons in the nucleus. Since the mass number is the sum of protons and neutrons, subtracting the number of neutrons (mass number) from the mass number gives you the number of protons (atomic number).
What instrument can be used to determine the identity of an element if its flame color is the same of another element?
Mass spectrometer would work.
How can one determine the density of an element?
To determine the density of an element, you would need to measure its mass and volume. The density of an element is calculated by dividing its mass by its volume. The formula for density is: Density Mass / Volume. By measuring the mass and volume of the element, you can then calculate its density.
Why would it be difficult to determine unknown liquids only be their flame tests?
no one knows That I am so sorry
How can you use boiling points and melting points to determine a solid liquid or gas that an element would be in at a certain temperature?
If the temperature is below the melting point then the element is a solid.If the temperature is above the melting point but below the boiling point, then the element is a liquid.If the temperature is above the boiling point, then the element is a gas.
What would be the best way to identify whether or not an unknown substance is made of a certain element?
One way to identify if an unknown substance is made of a certain element is to perform a chemical analysis, such as spectroscopy or mass spectrometry, to determine the elemental composition. Another method is to use techniques like X-ray diffraction to analyze the crystal structure, which can provide information about the type of elements present in the substance.
What is a unknown element that has a mass number of 22?
All elements that have an atomic mass of 22 are known. One example would be 22 sodium. Now, if you are talking about the atomic number of 22, that would be Titanium, which is also known.
What information could you use to determine the atomic number of an unknown element that has a mass number of 22?
the only element with a mass number of 22 is sodium (Na) which has an atomic number of 11. This is because the atomic number only represents the number of protons in the nucleus, while the mass number represents the number of protons and neutrons in the nucleus.
