<span>The answer is: more protons than neutrons The stability of the nucleus is based on the ratio of neutrons and protons present in the nucleus. if the number of protons is equal to the number neutrons then the nucleus is stable but in case the number of protons is more than the number neutrons or the other way round the nucleus to gain stability starts interconversion of neutron to proton or electron or decreases proton numbers. In case of nucleus containing high energy, the nucleus releases it. Such nuclei which release energy to gain stability are called radioactive nuclei and the phenomenon is called radioactivity.</span>

The two reactions illustrated in the diagrams below often occur when a foreign substance enters the body.
zheka24 [161]

The specific proteins produced by cell B in response to the foreign substance are antibodies.

<h3>What are antibodies?</h3>

Antibodies are specific proteins produced by the immune cells of the body in response to a foreign substance called antigen which produces the immune response.

Antibodies are released by immune cells such as B cells.

The antibodies bind to antigen and tag them for destruction by phagocytes.

Therefore, cell B will produce antibodies.

Calculate the pOH and the pH of a 5.0 x 10-2 M solution of NaOH.
k0ka [10]

Answer:

pOH = 1.3, pH = 12.7

Explanation:

Since NaOH is a strong base, it will completely ionize; further, since it completely ionizes, our hydroxide concentration (a product of the ionization) will be the same as the given concentration of NaOH.

NaOH -> Na⁺ + OH⁻, [OH⁻] = 5.0 x 10^-2 M

pOH is the negative log of the hydroxide concentration, so plug our hydroxide concentration in:

pOH = -log[OH⁻] = -log[5.0 x 10^-2 M] = 1.3

Since pH + pOH = 14, we can plug in pOH and solve for pH:

pH + 1.3 = 14

pH = 14 - 1.3 = 12.7

Thus, our pOH = 1.3 and pH = 12.7.
