0 electrons would be in the third shell. Because due to the fact that it only has 6 protons means that it is a Carbon element. There would be 2 electrons in the first shell, 4 in the second, and 0 in the third.

Calculate the pH of a buffer solution prepared by mixing 75.0 mL of 1.25 M lactic acid and 40.0 mL of 0.75 M sodium lactate. (Th
Naya [18.7K]

Answer:

pH = 3.37

Explanation:

A weak acid as lactic acid in a solution with sodium lactate (Its conjugate base) produce a buffer. The pH of this buffer is obtained using H-H equation:

pH = pKa + log [A-] / [HA]

<em>Where pH is the pH of the buffer,</em>

<em>pKa is 3.86</em>

<em>And [] could be taken as the moles of A- = Sodium lactate and HA = Lactic acid.</em>

<em />

Moles A-:

40.0mL = 0.0400L * (0.75mol / L) = 0.030 moles A-

Moles HA:

75.0mL = 0.0750L * (1.25mol / L) = 0.09375 moles HA

Replacing:

pH = 3.86+ log [0.030 moles A-] / [0.09375 moles HA]

<h3>pH = 3.37</h3>

What is the daughter nucleus produced when zn63 undergoes electron capture? replace each question mark with the appropriate inte
GarryVolchara [31]

The daughter nucleus that is produced is ₂₉⁶³cu.

What is Electron capture?

The process of drawing an electron to the nucleus, where it combines with a proton to create a neutron and a neutrino particle, is known as electron capture.

The daughter nucleus is the nucleus that is made by the parent nucleus. The nucleus that remains after the decay is called the daughter nucleus.

Here is the chemical formula for the reaction that results in the electron capture of the zinc-63 nucleus:

_A^ZX + e^- =  _A^Z_-_1 Y + ye

_3_0^6^3Zn\; + e^- = _2_9^6^3Cu + ye

Thus, the daughter nucleus produced when zn63 undergoes electron capture is _2_9^6^3Cu.

To learn more about Electron capture, refer to the below link:
