Option C: It is true for the majority of isotopes that the number of protons is less than the number of neutrons if the atomic mass is less than twice the atomic number.
An element is distinguished from another by its atomic number, which is based on how many protons it has. The total number of protons and neutrons determines an element's mass number.
The contemporary periodic table is set up so that each element has an increasing number of atoms, which leads to an increase in mass number.
You see, electrons, protons, and neutrons make up one atom. The valency of the atom is determined by the number of electrons in the outermost shell. The atomic number and a mass number of the atom are also related to the number of protons and neutrons in an atom.

when solute is added to a pure solvent what happens to the freezing point?
When a solute is added to a pure solvent the freezing point decreases as the boiling point increases.
The temperature at which a substance's liquid and solid forms have the same vapour pressure is known as its freezing point. Vapour pressure decreases as soon as a solute is added to the solvent. As a result, the temperature where the vapour pressure of the solid and liquid phases is equal is likewise decreased, and the freezing point is lowered as a result.
The temperature at which air pressure and vapour pressure are equal is known as the boiling point. Because there are fewer water molecules on the surface of the salt solution, fewer water molecules evaporate, resulting in lower vapour pressure. Therefore, a greater temperature was required to reach atmospheric pressure, consequently, the boiling point rises.
When something is frozen, it solidifies. Ice is made of water, compared to liquids, particles in solids are significantly closer to one another. To produce ice crystals, the water molecules must expend energy and get very near to one another (closely packed).

a certain substance has a heat of vaporization of 49.21 kj/mol. at what kelvin temperature will the vapor pressure be 5.00 times higher than it was at 293 k?
The vapor pressure will be 5.00 times higher than it was at 293 k at 393 k.
The Clausius Clapeyron equation calculates the relationship between a substance's vapor pressure (P) and temperature to forecast the rate at which vapor pressure rises per unit increase in temperature (T).
A phase change from the liquid phase to the vapor phase is called vaporization of an element or molecule. Both evaporation and boiling result in vaporization.
To find the temperature at which the vapor pressure will be 5.00 times higher than it was at 293 K, we can rearrange the equation to solve for T: We know,
[tex]T = \frac{del H}{(R * ln\frac{P_2}{P_1} )} + 293[/tex]
where P₁ is the vapor pressure at 293 K and P₂ is the vapor pressure at the desired temperature. Plugging in the values, we get:
[tex]T = \frac{49.21}{8.314*ln(5)} +293[/tex]

H2SO4 is our limiting reactant, and moles of H2SO4 will dictate the maximum amount of product that can be formed.
The correctly balanced equation for the reaction:
H2SO4(aq) + 2NaOH(s) ==> Na2SO4(aq) + 2H2O(l)
To find the limiting reactant. Divide moles of each reactant by the corresponding coefficient in a balanced equation and see which is less
For H2SO4: 29 g H2SO4 x 1 mol H2SO4/98 g = 0.294 mols (÷1->0.294)
For NaOH: 12 g NaOH x 1 mol NaOH / 40. g = 0.3 mols (÷2->0.15)
Since 0.294 is less than 0.15, H2SO4 is our limiting reactant, and moles of H2SO4 will dictate the maximum amount of product that can be formed
If the reaction finishes, there can be no more than zero grams of H2SO4 left over. There shouldn't be any left-over since it will run out before the NaOH is consumed.

Molal boiling-point elevation is a term used in thermodynamics and refers to the change in boiling point of a solvent due to the addition of a non-volatile solute. The molal boiling-point elevation is proportional to the molality (number of moles of solute per kilogram of solvent) of the solution and is an important colligative property, which means it depends only on the concentration of solute particles and not on their identity.
The molal boiling-point elevation can be calculated using the equation ΔTb = Kb × m, where ΔTb is the change in boiling point, Kb is the molal boiling-point elevation constant, and m is the molality of the solution. The value of Kb is different for each solvent and is used to quantify the effect of the solute on the boiling point of the solvent.
Molal boiling-point elevation has several important applications, including the purification of liquids by fractional distillation, the determination of the concentration of dissolved substances, and the production of high-purity solvents.

= Molarity (m) x Volume (L) x Molecular Weight (g/mol).
For sodium acetate, the molecular weight is 82.03 g/mol. Therefore, the mass of sodium acetate in a 0.500 m solution is:
= Mass (g)
= 0.500 m x 0.500 L x 82.03 g/mol
= 20.51 g
To obtain 0.170 mol of sodium acetate, use the following equation:-
= Moles (mol)
= Mass (g) / Molecular Weight (g/mol).
Therefore, the mass of sodium acetate required to obtain 0.170 mol is:
= Mass (g)
= 0.170 mol x 82.03 g/mol
= 13.74 g

using half equations explain how silver can be used to electroplate object
Answer:
Explanation:
Electroplating is the process of depositing a thin layer of one metal onto the surface of another metal or conductive material by means of an electrochemical reaction. In the case of silver electroplating, the following half reactions occur at the anode and cathode:
Anode (Oxidation): Ag(s) -> Ag+ (aq) + e-
Cathode (Reduction): Ag+ (aq) + e- -> Ag(s)
At the anode, silver atoms dissolve into the solution, releasing electrons and forming silver ions (Ag+). At the cathode, the silver ions gain electrons and precipitate out as solid silver atoms, which deposit onto the surface of the object being plated. This process continues until the desired thickness of silver has been deposited.
The anode and cathode are separated by a conductive material, typically an electrolyte solution, and a direct electrical current is applied to the system. The electrical current drives the reaction at the anode and cathode, with the electrons flowing from the anode to the cathode through the electrical circuit, allowing the silver ions to travel from the anode to the cathode, where they deposit as solid silver.
