Which option correctly compares beta decay and gamma decay? (1 point)

timofeeve [1]

The option which correctly compares beta decay and gamma decay 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 option which correctly compares beta decay and gamma decay 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.

On your first day working in a laboratory, you are told to make up 1 Liter of a 0.5 Molar Tris solution with a pH of 7.4. You me

GenaCL600 [577]

Answer:

60.57g of TRIS did you use

Explanation:

The concentration of the Tris solution buffer is 0.5 molar (That is, 0.5 moles per liter). As you need to make 1L, you need to have in the solution 0.5 moles of TRIS.

To convert these moles of TRIS to grams you need to use the molecular weight of TRIS base (121.14g/mol), thus:

0.5 moles TRIS * (121.14g / mol) =
