Answer:
Hydride ion
Explanation:
You often see the reduction with NADH written as
NADH ⟶ NAD⁺ + H⁺ + 2e⁻
If you think about it, H⁺ + 2e⁻ is equivalent to H:⁻, so we could write the reaction as
NADH ⟶ NAD⁺ + H:⁻
In terms of a mechanism, the dihydropyridine ring of NADH transfers a hydrogen atom with its pair of electrons (a hydride ion) to the substrate and becomes the more stable, aromatic pyridinium ion in NAD⁺.
Answer:
density= mass/volume
hence density of gold rock
= 386/20
=19.3 g/cc
Since you provide no options, Henry Moseley measured a property linked to Periodic Table position. After his revisions to the periodic table, Atomic number became more meaningful and the three pair of elements that seemed to be in the wrong order could be explained
Answer:
Force of Tension = 1832.8 N
Explanation:
Any mass of object supported or pulled by a rope or cable is subject to a force of tension. Since the mass is raised by a cable, tension is involved.
Mathematically,
Tension = mass × gravity(9.8 m/s²)
Tension can be represented as
T = (m × g) + (m × a)
Where g is the acceleration due to gravity of the object the cable is supporting and a is the acceleration on the object the cable is supporting. And m is the mass of the object.
mass = 158 kg
a = 1.8 m/s²
g = 9.8 m/s²
T = mg + ma
T = m(g + a)
T = 158(9.8 + 1.8)
T = 158 × 11.6
T = 1832.8 N
The <u>option which correctly compares beta decay and gamma decay</u> is Beta-decay releases a particle, while gamma decay only reduces the energy level. Beta-decay is a form of nuclear fission, but gamma decay is not.
Beta decay is a form of radioactivity in which an electron is released. The electron could be positively charged(positron) or negatively charged.
Also, beta decay also occurs when there is nuclear fission of a substance in which a larger atom breaksdown into a smaller atom and releases energy.
Gamma decay is a form of radioactivity in which photons are released without the release of a particle from the atom.
Since a photon is released, only the energy level of the atom reduces and is thus not a form of nuclear fission
So, the <u>option which correctly compares beta decay and gamma decay</u> is Beta-decay releases a particle, while gamma decay only reduces the energy level. Beta-decay is a form of nuclear fission, but gamma decay is not.
