Radiation is spontaneously emitted from hydrogen-3 nuclei, but radiation is not spontaneously emitted from hydrogen-1 nuclei or hydrogen-2 nuclei. Which hydrogen nuclei are stable
The hydrogen nuclei that are stable are hydrogen-1 nuclei or hydrogen-2 nuclei because radiation is not spontaneously emitted from them. Only the hydrogen – 3 nuclei is spontaneously emitted by radiation.
A scientist who wants to date materials older than 40,000 years would most likely use Potassium – argon dating or K-AR dating. Potassium-40 is a radioactive isotope of potassium that decays into argon-40. The half life of potassium-40 is 1.3 billion years far longer than carbon-14.
Answer:The answer would be uranium-238 hope this helps
Explanation:
Answer:
The correct answer is option A) Oxidation
The release of energy through the removal of hydrogen from a molecule is referred to as oxidation. In this process, energy is often released which can be utilized by cells for different functions.
The release of energy from a molecule by the removal of hydrogen is known as A) Oxidation. In biochemical reactions, oxidation refers to the process in which electrons are removed from a molecule, usually by removing a hydrogen atom (which consists of one proton and one electron). This process often releases energy that can be used by cells for various functions. Thus, through oxidation, molecules such as carbohydrates or fats can be broken down to release energy used for cellular activities.

B. The neutrons do not affect the mass or stability of an atom's nucleus, but they are involved in most interactions between two atoms.
C. The neutrons do not affect how the atom interacts with other atoms, but they do have an effect on the mass and stability of the nucleus.
b. Which of the following statements is true?
A) The average kinetic energy of the ice in cup A is less than that in cup
b.
B)The average kinetic energy of the ice in cup A is greater than that cup in
b.
C)The average kinetic energy of the ice cup A is equal to that in cup
b.
D)The average kinetic energies of the ice in cup A and the ice in cup B are not comparable.
Average kinetic energy is given by the formula:
KE(average) = 3/2*k*T
where k = Boltzmann constant = 1.38*10⁻²³ J/K
T = temperature in Kelvin (K)
Thus, the average KE is dependent only on temperature and independent of mass.
Since the temp in Cup A and B remains the same, the average KE will also be the same.
