What is the purpose of neutron radiation?
ki77a [65]

Answer:

Neutron radiation

Explanation:

Neutron radiation is a form of ionizing radiation that presents as free neutrons. Typical phenomena are nuclear fission or nuclear fusion causing the release of free neutrons, which then react with nuclei of other atoms to form new isotopes—which, in turn, may trigger further neutron radiation.

if carbon which has an electrongavity of 2.5 bonds with hydrogen, which has an electrongavity of 2.1, the bond between the two a
sukhopar [10]

Answer:

If carbon which has an electrongavity of 2.5 bonds with hydrogen, which has an electrongavity of 2.1, the bond between the two atoms will be classified as a(n) covalent bond → Totally TRUE

Explanation:

We must follow the Pauling's rules to solve these question.

The electonegativity of an element is defined as the ability it has to attract electrons that link it to another element. It is a periodic property, which allows predicting the polarity of the bond formed between two atoms, as well as its covalent or ionic character.

The Pauling scale values ​​range from 0.7 for Francium (the least electronegative element) to 4 for Fluorine, the most electronegative. Using the electronegativities table we can predict the polarity of some compounds

ΔEn (C-H) = 2.5 - 2.1 = 0.4 → This is a covalent bond.

ΔEn ≤ 0.4 → Covalent non polar bond

0.5 < ΔEn < 1.7 → Covalent polar bond

ΔEn ≥ 1.7 → Ionic bond

Calculate [H3O+] and [OH−] for each of the following solutions at 25 ∘C given the pH.<br> pH= 2.89
dimaraw [331]

Answer: The value of [H_{3}O^{+}] is 0.0012 M and [OH^{-}] is 1.02 \times 10^{-14}.

Explanation:

pH is the negative logarithm of concentration of hydrogen ion.

It is given that pH is 2.89. So, the value of concentration of hydrogen ions is calculated as follows.

pH = - log [H^{+}]\\2.89 = - log [H^{+}]\\conc. H^{+} = 0.0012 M

The relation between pH and pOH value is as follows.

pH + pOH = 14

0.0012 + pOH = 14

pOH = 14 - 0.0012 = 13.99

Now, pOH is the negative logarithm of concentration of hydroxide ions.

Hence, [OH^{-}] is calculated as follows.

pOH = - log [OH^{-}]\\13.99 = - log [OH^{-}]\\conc. OH^{-} = 1.02 \times 10^{-14} M

Thus, we can conclude that the value of [H_{3}O^{+}] is 0.0012 M and [OH^{-}] is 1.02 \times 10^{-14}.
