To find the total pressure in the flask, First we need to add up the partial pressures of the three gases.
After that we have to convert the partial pressure of oxygen to atmospheres and the partial pressure of ammonia to atmospheres.
1 atm = 760 torr
Therefore, the partial pressure of oxygen in atmospheres is:
886 torr / 760 torr/atm = 1.1667 atm
1 atm = 101.325 kPa
Then, the partial pressure of ammonia in atmospheres is:
2,487 kPa / 101.325 kPa/atm = 24.57 atm
The total pressure in the flask would be-
6.52 atm + 1.1667 atm + 24.57 atm = 32.2567 atm
Rounding to three decimal places:
32.2567 atm = 32.257 atm
Hence, The total pressure in the flask is 32.257 atm.

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).

When a solution with a nonvolatile solute is prepared, the freezing point and boiling point of the solution will decrease relative to the pure solvent.
Effect of Nonvolatile Solute on the Freezing Point and Boiling Point of a SolutionWhen a solution is prepared by dissolving a nonvolatile solute in a solvent, the presence of the solute particles in the solvent affects the behavior of the solution as compared to the pure solvent. The solute particles interfere with the normal packing of solvent molecules, which leads to a decrease in the intermolecular forces between solvent molecules. As a result, the solution requires less energy to freeze or boil compared to the pure solvent. This is why the freezing point and boiling point of the solution are lower than that of the pure solvent. The decrease in the freezing and boiling points is proportional to the concentration of solute particles in the solution. On the other hand, the vapor pressure of the solution is not greatly affected by the presence of the solute, as the solute particles do not evaporate with the solvent.

why licl is a solid at room temperature but ncl3 is a liquid with a relatively low boiling point in terms of attractive forces between particles
Answer:
Explanation:
The difference in the physical state of LiCl and NCl3 at room temperature is due to the difference in their intermolecular attractive forces.
LiCl has strong ionic bonds, which are strong attractive forces between positive and negative ions. These strong attractive forces result in a high melting and boiling point, making LiCl a solid at room temperature.
NCl3, on the other hand, has weaker covalent bonds, which are attractive forces between atoms in a molecule. These weaker attractive forces result in a lower melting and boiling point, making NCl3 a liquid with a relatively low boiling point at room temperature.
The strength of intermolecular forces is determined by the type of bond and the molecular structure. Ionic bonds are stronger than covalent bonds, and the stronger the bond, the higher the melting and boiling points of a substance.

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.

What determines whether or not an atom is reactive?
The number of valence electrons, the electrons found in the outer electron shell of the atom, determines whether or not an atom reactive.
Reactivity is the property of an atom in which it is either likely or unlikely to form a bond with another atom to create a molecule. The three types of bonds are ionic, covalent, and metallic. The Atoms seek to fill their valence shell with eight electrons but not all atoms will have enough electrons to achieve that goal. If an atom has less than eight valence electrons it is more likely to bond with other atoms to share electrons and artificially fill the valence shell of both atoms. The number of electrons in the outermost shell of an atom determines its reactivity. Noble gases have low reactivity because they have full electron shells. Halogens are highly reactive because they readily gain an electron to fill their outermost shell. Elements in the periodic table whose outermost shells are filled with electrons (8). Helium, neon, and argon are examples of noble gas elements. They are very non-reactive. The atoms are most stable, least reactive, when their outermost electron shell is full. Most of the elements important in biology need eight electrons in their outermost shell in order to be stable, and this rule of thumb is known as the octet rule.

Crystallization is used to separate a soluble material from a solvent. For example, crystallization can be used to separate salt from a salt solution. We begin with a soluble solid melt in a solvent.
So we can conclude that Crystallization is a powerful and adaptable technique to separate components from a liquid mixture.

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]
Solving for T, we get a temperature of approximately 393 K
