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 type of objects would you do carbon dating on?
On an object with unknown age but more than halflife of C
What information could you use to determine the atomic number of an unknown element that has the mass number of 22?
If you don't know the element, then you would need the number of electrons in a neutral atom of the element, which would be the same as the atomic number.
An unknown element X can form a compound with the formula XBr3 In which group on the Periodic Table would element X be found?
13
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.
Why would it be difficult to determine unknown liquids only be their flame tests?
no one knows That I am so sorry
Can you determine whether the atoms are the same element with out looking at the nuclei?
To a certain extent yes. In a balanced element the number of electrons match the number of protons in the core of the element. If electrons have been added or removed (as in an ion) then you would need to know the exact number added/removed, or rebalance the element, in order to determine the specific element.
What is The process of adding a known amount of solution of known concentration to determine the concentration of another solution is called?
titration is the best method to determine the unknown concentration of the unknown. if ur known is a solid then you would have to used distilled water to ensure it is submerged before you titrate.
What would be the best way to identify whether or not an unknown substance is made of a certain element?
By trying to break it down into other substances by chemical or physical means. If it eventually breaks down, it is not an element.
How would you describe the isotopes of hydrogen?
All atoms of a specific element have the same number of protons in their nucleus, but the number of neutrons in the nucleus may vary these are isotopes of that element.Hydrogen has several possible isotopes, only the first three of these are commonly referred to:hydrogen or protium or hydrogen-1, 1 proton 0 neutrons, stabledeuterium or hydrogen-2, 1 proton 1 neutron, stabletritium or hydrogen-3, 1 proton 2 neutrons, radioactive halflife 12.26 yearshydrogen-4, 1 proton 3 neutrons, radioactive halflife about 139 yoctosecondshydrogen-5, 1 proton 4 neutrons, radioactive halflife about 910 yoctosecondshydrogen-6, 1 proton 5 neutrons, radioactive halflife 290 yoctosecondshydrogen-7, 1 proton 6 neutrons, radioactive halflife 23 yoctosecondsetc.
What element forms a compound having the formula KXO4?
if X simply represents and unknown, then the compound would be potassium permanganate, KMnO4
What are the protons and newtrons of a banana?
A banana is not an element. You would have to determine the specific elements present and then figure out what their proton and neutron counts are.
