What are the similarities and differences in slurries, sols, pastes and gels?

Answer:

10 protons

Explanation:

The atomic number of an element is equal to the number of protons of the element. The atomic number of neon is 10. Therefore, neon contains 10 protons.

10 protons are in the nucleus of one atom of neon based on this information found in the Periodic Table.

The chemical elements are arranged in rows and columns in the periodic table, sometimes referred to as the periodic table of the elements. It is frequently used in physics, chemistry, and other disciplines and is frequently regarded as a symbol of chemistry.

The elements are organized in what is known as the periodic table. Columns and rows are used to organize the table. The horizontal rows are referred to as "periods," while the vertical columns are known as "groups."

Thus, The atomic number of an element is similar to the number of protons of the element. The atomic number of an element neon is 10. So, neon contains 10 protons.

pH=8.87

Reaction

C₂H₄O₂+NaOH⇒CH₃COONa+H₂O

at the equivalence point = mol C₂H₄O₂= mol NaOH

mol C₂H₄O₂ : 50 x 0.1 = 0.5 mlmol=5.10⁻⁴ mol

The two reactants have completely reacted, and there is only salt(CH₃COONa) and water(H₂O), there will be hydrolysis

For acids from weak acids and strong bases (the solution is alkaline) then the calculation:

[tex]\tt [OH^-]=\sqrt{\dfrac{Kw}{Ka}\times M }[/tex]

M=anion concentration=CH₃COO⁻

Ka=acid constant(for CH₃COOH,Ka=1.8.10⁻⁵)

[tex]\tt [OH^-]=\sqrt{\dfrac{10^{-14}}{1.8.10^{-5}}\times 0.1 }[/tex]

[tex]\tt [OH^-]=\sqrt{5.6.10^{-11}}=7.483\times 10^{-6}[/tex]

pOH=6-log 7.483=5.13

pH= 14 - 5.13=8.87

The pH of the solution is the negative log [H] concentration. The pH of the given solution is 8.87 at the equivalence point.

The given Reaction is:  

C₂H₄O₂+ NaOH ⇒ CH₃COON + H₂O

The pH of the solution can be calculated by,

[tex]\bold{pH = 14 - pOH}[/tex]................1

So first, calculate for pOH

[tex]\bold {pOH = \sqrt {\dfrac {Kw}{Ka} \times M}}[/tex]

Where,

Ka - dissociatioon constant = 50 x 0.1 = 0.5 ml = 5x10⁻⁴ mol

Kw - concentaion water ionic products = [tex]\bold {10^{-14}}[/tex]

M - anion concentration( CH₃COO⁻) = 0.1 M

Put the values in the formula,

[tex]\bold {pOH = \sqrt {\dfrac {\bold {10^{-14}}}{5\times 10^{-4} mol} \times 0.1}}\\\\\bold {pOH = 7.483 \times 10^{-6}}[/tex]

Since the pOH is the negative log of [OH⁻] concentration,

pOH = 6  -ln 7.483

pOH = 5.13

Put the value of pOH in the first equation,

pH= 14 - 5.13

pH = 8.87

Therefore, the pH of the given solution is 8.87 at the equivalence point.

Answer:

The charge would be +1

Explanation:

Protons have a positive charge while electrons have a negative charge. Therefore, it's simple subtraction. In every case, subtract the number of electrons from the number of protons.

13 - 12 = 1

Therefore the charge is +1

Here's one more example:

If the element chromium (Cr) has 24 protons and 28 electrons, what is its charge? Remember that protons have a positive charge and electrons have a negative charge.

24 - 28 = -4

Charge = -4

It would be written as followed when associating charge with a specific element: [tex]Cr^{-4}[/tex]

If an element has a neutral charge, that means the number of protons and neutrons are the same. If you look at the periodic table of elements, all of the elements listed have a neutral charge. The 0 isn't showed in the corner because it isn't necessary.

Bonus Information:

This isn't related to your question, but I've come across confusions when it comes to particles. Remember that protons (+) and electrons (-) are the only particles that have a charge, therefore, as it says in it's name, neutrons are neutral or have no charge. Neutrons do not contribute to charge, but they do contribute to the mass of an atom. So the number of protons added to the number of neutrons equate to the mass of an atom. Electrons have mass, but it's so miniscule and insignificant that it doesn't even contribute to the overall mass of the atom, so don't count those.

Remember:

C = p - e

M = p + n

C = atomic charge, M = atomic mass, p =protons, n = neutrons, e = electrons
