A rock originally had 1500 atoms of U-235 and it now has 750 how old is it?
For a rock to have started with 1500 atoms of any element and now have 750 it has undergone radioactive decay equal to one full half life (i.e. there are half the number of atoms now than at the beginning).Uranium-235 has a half life of 7.038×108 years.As such, the rock is 7.038×108 or 703 million years old.
What is the atomic number of uranium and how many neutrons does the isotope uranium-235 have?
The atomic number of uranium is 92. The number of neutrons of the isotope uranium-235 is 143.
How many protons and electrons in uranium 235?
Neutrons 143 Protons 92 92+143=235 For other isotopes: number of neutrons = atomic mass (or mass number) - number of protons
How many moles are there in 9.4 g of NaOH?
Molecular mass of NaOH= 40.0 grams9.40 grams / (40.0 grams) = .235 moles NaOH
How is the energy stored in uranium?
Uranium-235 has the property of undergoing fission (splitting) when it absorbs another neutron, and this fission releases energy in the form of heat. Energy cannot be put back into the uranium, it is a one-way process which destroys the uranium nucleus and forms other lighter elements.
Which of the following is a fusion reaction- uranium-235 absorbing a neutron and splitting into xenon-140 strontium-94 and two neutrons hydrochloric acid combining with sodium hydroxide to form NaCl?
Neither is. The uranium splitting is a fission reaction while the reaction between hydrochloric acid and sodium chloride is a chemical acid-base reaction.
What are 2 nuclear reactions?
The two main categories are (1) fusion: joining small atoms into larger atoms, such as hydrogen-1 into helium-4, and (2) fission, the splitting of certain large atoms, such as U-235.The two main categories are (1) fusion: joining small atoms into larger atoms, such as hydrogen-1 into helium-4, and (2) fission, the splitting of certain large atoms, such as U-235.The two main categories are (1) fusion: joining small atoms into larger atoms, such as hydrogen-1 into helium-4, and (2) fission, the splitting of certain large atoms, such as U-235.The two main categories are (1) fusion: joining small atoms into larger atoms, such as hydrogen-1 into helium-4, and (2) fission, the splitting of certain large atoms, such as U-235.
How many grams of copper atoms are needed to supply the same number of atoms as does 235 grams of iron?
The number of atoms in a given mass of metal may be calculated by dividing the mass by the gram atomic mass, then multiplying by Avogadro's Number. The gram atomic masses of iron and copper are 55.847 and 63.546 respectively. Since Avogadro's Number is constant, the required mass m of copper atoms can be found from the equation m/63.546 = 235/63.546, or m = 235 X (63.456/55.847), or 267 grams of copper, to the justified number of significant digits.
How many shingles are in a bundle of 235?
I am not positive but if it is in a package of 235 i am pretty sure it is 235!
How many 5s in 235?
235 ÷ 5 = 47
What is nuculer energy?
Nuclear energy is energy obtained from changes within atomic nuclei. When light atoms combine to form heavier atoms (for example, deuterium is converted to helium), it is called "fusion". When heavy atoms (for example, uranium-235) split, it is called "fission".Nuclear energy is energy obtained from changes within atomic nuclei.
