How many unchanges atoms would remain after 3 half lives if the initial sample had 600 unchanged atoms?
Only 75 atoms
What does a googol of atoms equal?
One googol of atoms would be 10100 atoms or 1.66 × 1076 moles.
How many atoms would be found in a single molecule that has the chemical formula?
2 atoms of S + 10 atoms of F = 12 atoms total
How many hydrogen atoms does caffeine has?
To answer your question on how many hydrogen atoms are there in caffeine, the scientific answer would be 10 atoms of hydrogen.
How many atoms are in Pepsi?
You would first need to know the mass of the soda cap. This is how you would do it.... the mass multiplied by 1 mol/the molar mass multiplied by 6.02x1023 . Then you would be left with the about of atoms.
How many unchanges atoms would remain after 3 half lives if the initial sample had 600 unchanged atoms?
Only 75 atoms
What would happened if you were in a black hole?
You would get completely destroyed, due to the extreme gravity. Not even atoms would remain.
What happens when one goes into a black hole?
You would get utterly destroyed. Not even atoms remain in such a case.
Can atoms be divided by chemical reaction?
No, this would be contrary to the definition of an ordinary chemical reaction.
What type of objects would you do carbon dating on?
On an object with unknown age but more than halflife of C
How many years would it take for 3.0 kg tritium to decay to 0.75 kg tritium?
In ordinary water, exactly 0 atoms as Tritium decays too rapidly (halflife 12.26 years) for any that was on earth when it formed (billions of years ago) to remain. In contaminated water, either deliberately or accidentally, it would depend on how much contaminate was added and the tritium concentration in it. Tritium can only be manufactured somewhere there is a high neutron flux (e.g., nuclear reactor or bomb, a star).
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 did democritus of adbera discover?
Democritus proposed that all matter is made up atoms and he coined the term "atomos", or atoms, which means indivisible. He claimed atoms could not be destroyed and that matter would remain the same, even if it is sliced into the smallest possible quantity.
How would the earth would be like if there was no atoms?
There wouldn't be an earth if there were no atoms.
If a certain radioactive substance has a half life of one year how many atoms of the substance remain after 5 years if there are initially 5000 such atoms?
Half life refers to the time required for the change (decay) of a radioactive nucleus to a lighter, possibly more stable, nucleus.Starting with 5,000 radioactive atoms, at the end of first year, half would have decayed leaving 2,500. Following the same pattern, the end of the second year would see only 1,250. By the end of year 5, there would be just 156 radioactive atoms.
How big would it be if you had a googolplex of atoms?
There are fewer than a googol atoms in the known universe so a googolplex atoms would be outrageously huge.
If you took 1 Valium 3 weeks before a drug test would it show up in your urine?
no, look at its halflife (how long until half of it is gone from ur body)
