The electronegativity of the element a is more important for elements in the same period of the periodic table, whereas bond strength is more important for elements in the same group.
Period: The horizontal rows are known as periods. Each period will corresponds to the successive occupation of the orbitals in a valence shell of the atom, with the long periods corresponding to the occupation of the orbitals of the d-subshell.
Group: The vertical columns in a periodic table are known as groups. There are 18 numbered groups in the periodic table; the 14 f-block columns, between the groups 2 and 3, are not numbered. The elements in a group have similar physical as well as chemical characteristics of the outermost electron shells of their atoms because the most chemical properties are dominated by the orbital location of the outermost electron.

What mass of CO2 is produced when 10.0 g of CH4 is burned in oxygen?
Taking into account the reaction stoichiometry, 27.5 grams of CO₂ is produced when 10.0 g of CH₄ is burned in oxygen.
Reaction stoichiometryIn first place, the balanced reaction is:
CH₄ + 2 O₂ → CO₂ + 2 H₂O
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
CH₄: 1 moleO₂: 2 molesCO₂: 1 moleH₂O: 2 molesThe molar mass of the compounds is:
CH₄: 16 g/moleO₂: 32 g/moleCO₂: 44 g/moleH₂O: 18 g/moleBy reaction stoichiometry, the following mass quantities of each compound participate in the reaction:
CH₄: 1 mole ×16 g/mole= 16 gramsO₂: 2 moles ×32 g/mole= 64 gramsCO₂: 1 mole ×44 g/mole= 44 gramsH₂O: 2 moles ×18 g/mole= 36 gramsMass of CO₂ formed
It is possible to use a simple rule of three as follows: if by reaction stoichiometry 16 grams of CH₄ form 44 grams of CO₂, 10 grams of CH₄ form how much mass of CO₂?
mass of CO₂= (10 grams of CH₄×44 grams of CO₂)÷16 grams of CH₄

The conversion of units is a process of changing one unit to another, while preserving the same value.
The conversion of units2.62e-7 lb/ft^3 (3 sig figs)
To convert 53.7 μg/mL to lb/ft^3, we will use the conversion factor of 1 lb/ft^3 = 16,018,000 μg/mL.To begin, we will multiply 53.7 μg/mL by the conversion factor of 16,018,000 μg/mL.53.7 μg/mL * 16,018,000 μg/mL = 860,686,600 μg/mLNext, we will divide the result by 16,018,000 μg/mL to get the answer in lb/ft^3.860,686,600 μg/mL ÷ 16,018,000 μg/mL = 53.7 lb/ft^3Therefore, 53.7 μg/mL is equal to 53.7 lb/ft^3. The units of the answer are lb/ft^3 and the answer is rounded to two significant figures.The conversion from micrograms per milliliter (μg/mL) to pounds per cubic foot (lb/ft^3) is not a direct conversion, since they measure different units. To convert from one to the other, we must first convert the given mass of 53.7 μg/mL to pounds.To do this, we can use the conversion of 1 lb = 453,592 μg. This means that 53.7 μg/mL is equivalent to 0.0001185 lb.Next, we must convert from pounds to pounds per cubic foot. To do this, we can use the conversion of 1 lb/ft^3 = 16.02 lb. This means that 0.0001185 lb is equivalent to 0.000743 lb/ft^3.Therefore, the conversion of 53.7 μg/mL to lb/ft^3 is 0.000743 lb/ft^3.

A solution is prepared by dissolving 1.65 g of an unknown organic compound in 15.00 g of cyclohexane. What is the molar mass of the compound if the solution has a melting point of -6.3°C? See the table for information about cyclohexane.
Can anyone help?
The molar mass of the unknown organic compound is approximately 15.0 g/mol.
What is an organic compound?An organic compound can be described as any chemical compound that contains carbon-hydrogen or carbon-carbon bonds.
The molality of the solution can be calculated as follows:
M = moles of solute / mass of solvent (in g)
M = 1.65 g / (molecular weight of solute) / 15.00 g = 0.110 mol/kg
We will use the value of Kf_ for cyclohexane (20.0°C/m), the ΔT can be calculated as follows:
ΔT = Kf_ * m = 20.0°C/m * 0.110 mol/kg = 2.20°C
So the melting point of the solution is:
Tf_ (solution) = Tf_ (pure solvent) - ΔT = 6.6°C - 2.20°C = -0.1°C
The molecular weight of the solute can be calculated as follows:
molecular weight = moles of solute / molality = 1.65 g / (0.110 mol/kg) = 15.0 g/mol
Therefore, we can conclude that the molar mass of the unknown organic compound is approximately 15.0 g/mol.

Suppose that flerovium-289 underwent decay by the sequential decay of two alpha particles. What is the name of the final isotope that is produced?
The final isotope that is produced after flerovium-289 undergoes decay by the sequential decay of two alpha particles is Lead-281.
Flerovium-289 is an unstable isotope that is known to decay through alpha decay, which involves the emission of an alpha particle (a helium nucleus) from the nucleus of the atom. An alpha particle is made up of two protons and two neutrons. When an atom undergoes alpha decay, it loses two protons and two neutrons from its nucleus, which reduces its atomic number by 2 and its mass number by 4.
In the case of flerovium-289, the atomic number of flerovium is 114, after emitting 2 alpha particles, the atomic number would be 110, which corresponds to the element lead. The mass number of flerovium-289 is 289, after emitting 2 alpha particles the mass number would be 285, which corresponds to the isotope of lead-281.
Therefore, the final isotope that is produced after flerovium-289 undergoes decay by the sequential decay of two alpha particles is Lead-281.

Acidic oxides are Carbon dioxide([tex]CO_{2}[/tex]), Phosphorus pentoxide([tex]P_{2}$O_{5}[/tex]) and Sulfur dioxide([tex]S$O_{2}[/tex] ).
Basic oxide are Magnesium Oxide(MgO).
Amphoteric oxides are Tin(Stannum) Oxide(SnO), Antimony trioxide([tex]Sb_{2} $O_{3}[/tex]), Aluminum oxide([tex]Al_{2} O_{3}[/tex] ) and Beryllium oxide(BeO).
Magnesium Oxide(MgO) is a basic oxide.
Magnesium is a metal that, like the majority of metals, forms simple oxides.
Tin(Stannum) Oxide(SnO) is amphoteric oxide.
Since SnO reacts with both HCl (an acid) and NaOH (a base) to produce salt and water, its amphoteric nature may be demonstrated.
Carbon dioxide([tex]CO_{2}[/tex]) itself is not an acid, because it does not contain hydrogen ions (H +), but instead transforms into carbonic acid when dissolved in water. Water and carbon dioxide combine to generate carbonic acid, which makes the solution acidic.
Phosphorus pentoxide([tex]P_{2}$O_{5}[/tex]) is an acidic oxide.
Because it is an anhydride of phosphoric acid, phosphorus pentoxide is an acidic oxide that is employed as a desiccating and dehydrating agent.
Antimony trioxide([tex]Sb_{2} $O_{3}[/tex]) is an amphoteric.
It dissolves in aqueous sodium hydroxide solution to produce the trihydrate of the meta-antimonite [tex]NaSbO_{2}[/tex].
Sulfur dioxide([tex]S$O_{2}[/tex] ) is an acidic oxide.
[tex]S$O_{2}[/tex] occurs spontaneously during volcanic eruptions and is mostly caused by the burning of fossil fuels. The lungs can be harmed by [tex]S$O_{2}[/tex] inhalation.
Aluminum oxide([tex]Al_{2} O_{3}[/tex] ) is an amphoteric oxide'
This substance possesses both acidic and basic properties. The other reactant in the chemical reaction determines whether [tex]Al_{2} O_{3}[/tex] is basic or acidic.

Answer:
D. 2H_{g}*O(g) -> 2H_{g}(g) + O_{g}(g)
The reaction 2N*H_{3}(g) -> N_{3}(g) + 3H_{3}(g) would have a decrease in entropy. In this reaction, the number of moles of gas on the right side of the equation is greater than on the left side, so the entropy increases. The other reactions would have an increase in entropy.
For each reaction, calculate Hrxn, Srxn, and Grxn at 25 C and state whether the reaction is spontaneous. If the reaction is not spontaneous, would a change in temperature make it spontaneous?
If so, should the temperature be raised or lowered from 25 C?
To calculate the enthalpy, entropy, and Gibbs free energy of a reaction, you need to know the enthalpy, entropy, and Gibbs free energy of each of the products and reactants.
Once you have these values, you can calculate the enthalpy, entropy, and Gibbs free energy of the reaction by subtracting the values of the reactants from the values of the products. For example, if the enthalpy of a reactant is -240 kJ/mol and the enthalpy of a product is 0 kJ/mol, then the enthalpy of the reaction is +240 kJ/mol.
If the reaction is not spontaneous at 25°C, then a change in temperature may make it spontaneous. Raising the temperature will generally increase the entropy of the reaction, and will make the reaction more spontaneous. Conversely, lowering the temperature will generally decrease the entropy of the reaction, and will make the reaction less spontaneous.
