What are the important things about the periodic table?
The periodic table is a chart that arranges elements in a useful and logical manner. Elements are listed in order of increasing atomic number, lined up so elements that exhibit similar properties are arranged in similar rows or columns as others.
There is a total of about 94 elements on the periodic table that occur in nature. Remaining all of the other elements are strictly human-made. Some sources state most elements occur naturally because heavy elements may transition between elements as they undergo radioactive decay.
The First artificially made element was Technetium. Technetium is the lightest element that has only radioactive isotopes (none are stable).
The rows in the periodic table are called periods.

A solution of 9% (by weight) ethylene glycol (62 g/mol) in water at 25 °C has a vapor pressure of 23.1 torr.
Raoult's Law.
Consider a 100 g solution.
Ethylene glycol mass is 9 g
water mass is 100 g - 9 g = 91 g moles.
Ethylene glycol = 9 g times 1 mole/62 g =0.1451 moles.
moles water = 9 g x 1 mole/18 g = 5.0555 moles water
Total moles are equal to 0.1451 + 5.0555 = 5.2006 moles
the mole percentage of water = 5.0555 moles/5.2006 moles = 0.9720

The Energy of Proton:
The energy of a photon has a direct relationship with the frequency of the photon. It can be defined as the energy a single photon carries.
The amount of energy is directly proportional to the photon's electromagnetic frequency and thus, equivalently, is inversely proportional to the wavelength.
Given that:

please explain why bulk polymerization are rarely adopted for large scale free radical polymerization?
Bulk polymerization is rarely adopted for large scale free radical polymerization because the process is not easily controlled
Bulk polymerization is an open system in which the reactants are not isolated from the surrounding environment, making it possible for external sources to influence the reaction conditions. In bulk polymerization, the entire mixture of monomers, initiator, and catalysts is placed in a single vessel and the reaction proceeds in a single, large-scale batch. This can lead to a number of problems, including uneven heat distribution, oxygen depletion, and uncontrolled reaction rates. Moreover, it is difficult to separate the desired product from the unreacted monomers and other byproducts, which can lead to product contamination. Additionally, bulk polymerization is usually limited to lower molecular weight poly This type of polymerization makes it difficult to maintain a constant monomer concentration and reaction temperature, both of which are crucial components in regulating free radical polymerization. In addition, bulk polymerization is more likely to produce byproducts that degrade the polymer's quality. All of these problems make bulk polymerization an ineffective and potentially hazardous choice for large-scale free radical polymerization.

Which factor causes a decrease in the rate of dissolution?decreasing the amount of soluteincreasing the stirring of the solutiondecreasing the surface area of the soluteincreasing the temperature of the solvent.
lessen the solute content slow down the rate of dissolution.
what is dissolution?By dissolving the solute in the solvent, a solution is created. Dissolution is the process through which solutes that have been dissolved into a solvent form a solution. A solution of the gas, liquid, or solid in the original solvent is created during this procedure.
Solution stirring: Solution stirring results in a greater interaction between the solvent and the solute, speeding up the rate of dissolution.
The solute's surface area is: It is easier for the solute to interact with the solvent when the solute has a lower surface area. Therefore, the rate of disintegration increases with decreasing surface area.
Temperature of the Solvent Because the solvent's molecules have more energy at higher temperatures, more substances often dissolve in it, which increases the amount of molecular interaction between the solvent's and solute's molecules.
Because there is less solute in the solution, there will be less contact between the solute and the solvent, which will result in a slower rate of dissolution (even though a solution will still be formed).

the fluorine- nuclide radioactively decays by electron capture. write a balanced nuclear chemical equation that describes this process.
The fluorine - nuclide radioactively decays by electron capture. (9+1)18F -> (8)18O + e^- + v_e is the balanced nuclear chemical equation that describes this process.
Radioactive decay is a process in which an unstable nucleus emits particles or radiation in order to become more stable. Electron capture is a type of radioactive decay in which an inner atomic electron is captured by the nucleus, combining with a proton to form a neutron. This process results in the emission of an electron neutrino and a reduction in the atomic number of the nucleus by one.
To write a balanced nuclear chemical equation that describes the electron capture decay of a fluorine-nuclide, we can use the following general form:
(Z+1)A X -> (Z)A Y + e^- + v_e
where (Z+1)A X is the initial nuclide, (Z)A Y is the final nuclide, e^- is the captured electron, and v_e is the electron neutrino. The atomic number (Z) and mass number (A) of the nuclides are indicated in parentheses.
In this case, the initial nuclide is the fluorine-nuclide, which has an atomic number of 9 (Z+1) and a mass number of 18 (A). The final nuclide is an isotope of oxygen, which has an atomic number of 8 (Z) and the same mass number as the initial nuclide (A).
The balanced nuclear chemical equation for the electron capture decay of the fluorine-nuclide would be:
(9+1)18F -> (8)18O + e^- + v_e
It is important to note that this is a general equation for electron capture decay and does not represent the specific decay of any particular fluorine-nuclide. The actual decay of a specific nuclide may involve the emission of other particles or radiation in addition to the electron and electron neutrino.

a 100 ml solution containing 0.100 m nahco3 is treated with excess acid, producing carbon dioxide which is released into the atmosphere. how much work (in j) is done by the co2 if this reaction occurs at 298k and 1 atmosphere of pressure?
If the reaction occurs at 298K and 1 atmosphere of pressure, the work done by the CO₂ is -24.8 Joules.
How to calculate work (in joule) is done by the CO₂ if the reaction occurs at 298K and 1atm of pressure?Work is the energy required to move something against a force. The energy of a system can change due to work and other forms of energy transfer such as heat. Gases do expansion or compression work with the equation W = - P * ΔV.
From the question given
molarity of (NaHCO₃) = 0.1m
Volume of NaHCO₃ (V) = 100ml * 10⁻³ L / 1 ml = 0.1L
T (temperature) = 298k
P (pressure) = 1atm
moles of NaHCO₃
= molarity * Volume in Liters
= 0.1m * 0.1L = 0.01L
NaHCO₃ + HCl -> CO₂ + H₂O + NaCl
moles of CO₂ = moles of NaHCO₃ * (coefficient of CO₂ / Coefficient of NaHCO₃)
= 0.01L * 1/1
= 0.01 mol (moles of CO₂)
so, initial moles of CO₂ = 0
final moles of CO₂ = 0.01mol (based from the calculation)
Δn 0.01 - 0 = 0.01mol
Now, let's use work formula (as mentioned above on explanation part)
Work = - P * ΔV
= - Δn * R *T
Where R = 8.314J / mol.K
= - ( 0.01mol * 8.314 J / mol*K * 298K)

• NaCl and aqueous AgNO3 (aqueous) AgCl + NaNO3 in water;
Mg(OH)2 + 2HCl in water; MgCl2 (aqueous) + 2H2O(l)
How do you recognize a precipitation reaction in an equation?
Usually, only net ionic equations are used to describe precipitation reactions. A net ionic equation cannot be stated if all products are watery since all ions cancel each other out as spectator ions. As a result, there is no precipitation response.
An illustration of a precipitate equation
Precipitation reaction examples include adding 2 KI (aq.), 2 KNO3 (aq.), and PbI2 (s/ppt). Sodium chloride (NaCl) and insoluble barium sulfate are produced by the reaction of barium chloride (BaCl2) and sodium sulfate (Na2SO4) (BaSO4).
