a radioactive nuclide that is used for geological dating has an atomic number of 19 and mass 40. what is the symbol of this nucl

PIT_PIT [208]

The symbol of the radioactive nuclide, given the data is ⁴⁰₁₉K

<h3>Data obtained from the question</h3>

Atomic number = 19
Mass number = 40
Symbol of nuclide =?

<h3>How to determine the nuclide</h3>

From the question given above, the atomic number of the nuclide is 19.

Comparing the atomic number (i.e 19) of the nuclide with those in the periodic table, the nuclide is potassium with a symbol of K

<h3>How to determine the symbol of the nuclide</h3>

Atomic number (Z) = 19
Mass number (A) = 40
Name of nuclide = Potassium (K)
Symbol of nuclide =?

The symbol of a nuclide is given as ᴬ₂X

Where

A is the mass number
Z is the atomic number
X is the symbol of the element

Thus,

ᴬ₂X => ⁴⁰₁₉K

Therefore, the symbol of the nuclide is ⁴⁰₁₉K

To three significant digit,what is the mass percentage of iron in the compound Fe2O3

svlad2 [7]

69.9%

Explanation:

To find the mass percentage of iron in the compound in Fe₂O₃, we would go ahead to express the given molar mass of the iron to that of the compound.

Mass percentage = $\frac{molar mass of Fe}{Molar mass of Fe_{2}O_{3} }$ x 100

Molar mass of Fe = 55.85g/mol

Molar mass of O = 16g/mol

Molar mass of Fe₂O₃ = 2(55.85) + 3(16) = 159.7‬g/mol

Mass percentage = $\frac{2(55.85)}{159.7} x 100$ = 69.94% = 69.9%

0.556 g of a solid white acid are dissolved in water and completely neutralized by the addition of 52.38 mL of 0.396 M NaOH. Cal

Veseljchak [2.6K]

Answer:

$M_{acid}=26.804g/mol$

Explanation:

Hello,

In this case, by knowing that the used NaOH equals in moles the acid (monoprotic) as shown below, during the titration:

$n_{acid}=n_{NaOH}$

By knowing the volume and the concentration of the NaOH, one obtains:

$n_{acid}=0.05238L*0.396\frac{mol}{L}=0.0207mol$

Thus, the molar mass of the acid is computed based on the previously computed moles and the given mass as follows:

$M_{acid}=\frac{m_{acid}}{n_{acid}}=\frac{0.556g}{0.0207mol}=26.804g/mol$

Best regards.
