Which of the following has 62 neutrons, 46 protons, and 46 electrons?​

Answer:

Giant cell, also called Langhans giant cell, large cell characterized by an arc of nuclei toward the outer membrane. The cell is formed by the fusion of epithelioid cells, which are derived from immune cells called macrophages. Once fused, these cells share the same cytoplasm, and their nuclei become arranged in an arc near the outer edge of the cell. Langhans giant cells typically form at the centre of granulomas (aggregates of macrophages) and are found in the tubercle, or primary focus of infection, in tuberculosis, in lesions of syphilis, leprosy, and sarcoidosis, and in fungal infections.Large cells that form by fusion in reaction to the presence in the body of foreign substances differ from Langhans giant cells in that their many nuclei are scattered throughout the cell. In giant-cell tumours of bone and tendon the cells have many nuclei crowded together. The megakaryocytes, the normal bone-marrow cells thought to be the source of the blood platelets, are also called giant cells.

Atoms are the smallest division of the element. The potassium atoms present in the 235 gm of the compound is \(2.57 \times 10^{24}\) atoms.

Given,

Calculate the number of moles as:

\(\begin{aligned}\rm Moles (n) &= \dfrac{\rm mass}{\rm molar\;\rm mass}\\\\&= \dfrac{235}{110.26}\\\\&=2.13\;\rm mol\end{aligned}\)

In the given compound \(\rm K_{2}S\), there are two atoms of potassium and one atom of sulphur.

If, 1 mole = \(2 \times 6.022 \times 10^{23}\) atoms of potassium

Then, 2.13 moles = X atoms

Solving for X:

\(2.13 \times 2 \times 6.022 \times 10^{23} = 2.57 \times 10^{24}\)

Therefore, option c. \(2.57 \times 10^{24}\) is correct.

"the number of ions produced by one formula unit of the electrolyte," refers to the van't Hoff factor (i) in an ideal solution of a strong electrolyte. It represents the extent of dissociation of the electrolyte into ions.

In an ideal solution of a strong electrolyte, the van't Hoff factor (i) represents the number of ions that are produced when one formula unit of the electrolyte dissociates completely in the solution. It is a measure of the extent of dissociation of the electrolyte.

For example, for a strong electrolyte such as sodium chloride (NaCl), when it dissolves in water, it completely dissociates into sodium ions (Na+) and chloride ions (Cl-). In this case, the van't Hoff factor (i) would be 2 because one formula unit of NaCl produces two ions (Na+ and Cl-).

Similarly, for other strong electrolytes, the van't Hoff factor (i) can be determined based on the number of ions produced per formula unit. It is important to note that for non-electrolytes or weak electrolytes, the van't Hoff factor (i) is typically less than 1, indicating partial dissociation or no dissociation in the solution.

Answer:i dont know thats why imon her

Explanation:

The original concentration of the sodium oxalate was 0.0675 M.

The balanced equation for the reaction between potassium permanganate (KMnO₄) and sodium oxalate (Na₂C₂O₄) is:

5 C₂O₄²⁻ + 2 MnO₄⁻ + 16 H⁺ → 2 Mn²⁺ + 10 CO₂ + 8 H₂O

From the balanced equation, we can see that 5 moles of sodium oxalate react with 2 moles of potassium permanganate. Therefore, the number of moles of potassium permanganate used in the titration is:

n(KMnO₄) = M(KMnO₄) x V(KMnO₄) = 0.1500 M x 22.30 mL x (1 L/1000 mL) = 0.003345 moles

Using the stoichiometry of the balanced equation, we can determine the number of moles of sodium oxalate that reacted:

n(Na₂C₂O₄) = (5/2) x n(KMnO₄) = (5/2) x 0.003345 moles = 0.008362 moles

Finally, we can calculate the concentration of the original sodium oxalate solution:

M(Na₂C₂O₄) = n(Na₂C₂O₄) / V(Na₂C₂O₄) = 0.008362 moles / 10.00 mL x (1 L/1000 mL) = 0.0675 M

Explanation:

This reaction is a decomposition reaction because one substance (NaNO3) is being separated into two substances (NaNO2 and O2). Alternatively, you could use the process of elimination. The reaction can't be single/double replacement because there's only one reactant, it can't be synthesis because substances are being broken down, not formed, and it can't be combustion because O2 is a product, not a reactant, and CO2 and H2O aren't being produced, as is common with combustion reactions.

While comparing two compounds observed in the same chemical reaction, chemical equation of the reaction like information is needed to convert from grams of one substance to grams of the other substance.

To convert from grams of one substance to grams of the other substance in a chemical reaction, you need to know the chemical equation for the reaction and the relative proportions of the substances in the reactants and products.

For example, consider the following chemical equation:

2 H2 + O2 ---> 2 H2O

In this equation, compounds and the reactants are 2 molecules of hydrogen gas (H2) and 1 molecule of oxygen gas (O2). The products are 2 molecules of water (H2O). The coefficient 2 in front of H2O indicates that 2 molecules of water are produced for every 1 molecule of oxygen gas and 2 molecules of hydrogen gas. If you know the mass of one of the substances (either H2, O2, or H2O) in the reaction, you can use the coefficients in the chemical equation to convert the mass to the corresponding mass of the other substance. For example, if you know the mass of H2O, you can use the coefficient 2 in front of H2O to convert the mass to the corresponding mass of H2 or O2. Similarly, if you know the mass of H2 or O2, you can use the coefficients in front of these substances to convert the mass to the corresponding mass of H2O. It is important to note that the conversion from grams of one substance to grams of the other substance is only accurate if the chemical reaction is balanced, meaning that the number of atoms of each element is the same on both sides of the equation. If the chemical equation is not balanced, the conversion will not be accurate.

The correct way to write the thermochemical equation for the given exothermic reaction is: \(C_3H_8\)= 3C + 4H₂ + Energy Option A

In a thermochemical equation, the energy term is typically written on the product side of the equation. This is because in an exothermic reaction, energy is released as a product. The product side of the equation represents the lower-energy state of the system after the reaction has occurred.

In the given reaction, propane (\(C_3H_8\)) is the product, and energy is released during its formation. Therefore, the correct representation of the thermochemical equation is \(C_3H_8\) = 3C + 4H₂ + Energy.

Option B) 3C + 4H2 \(C_3H_8\) + Energy is incorrect because it incorrectly places the energy term on the reactant side of the equation. The energy term should always be placed on the product side to indicate the energy released during the exothermic reaction.

Option A) Energy + 3C + 4H₂ = \(C_3H_8\) is also incorrect because it places the energy term at the beginning of the equation. The energy term should be placed after the products to signify that it is released during the reaction, rather than being consumed.

Therefore, the correct way to write the thermochemical equation for the given exothermic reaction is \(C_3H_8\) = 3C + 4H₂ + Energy Option A
