The product of the gamma decay reaction is 22/10 Ne
What is gamma decay ?Gamma radiation, commonly referred to as gamma decay, is a type of radioactive decay in which an unstable atomic nucleus generates gamma rays, a form of extremely high-energy electromagnetic radiation.
Gamma rays are neutral and have no mass, in contrast to alpha and beta particles, which have mass and charge.
The result of the gamma decay would not alter the parent nuclei thus the product would have the same mass and charge as the parent nucleus.

The compound oxygen difluoride is quite reactive, giving oxygen and HF when treated with water. -126kj is the bond dissociation energy of the O–F bond in OF[tex]_2[/tex].
The amount of energy necessary to homolytically shatter a chemical bond is known as bond dissociation energy. Radical species are often produced by a homolytic fracture. The abbreviations BDE, D0, and DH° are used to denote this energy.
Bond dissociation power is frequently used to gauge a chemical bond's strength as well as for contrasting different bonds. Be aware that the enthalpy change depends on the temperature. Bond dissociation energy is often measured in kJ/mol or kcal/mol.
-318 kJ/mol = BDE for OF[tex]_2[/tex]+ BDE for H[tex]_2[/tex]O - BDE for O[tex]_2[/tex] - 2 x BDE for HF.

If 0.499 g of NaOH (MM = 40.00 g/mol) is dissolved in 150.00 mL of water, what is the theoretical molarity of NaOH? (do not forget about SF)
Molarity is an important method which is used to calculate the concentration of a solution. The molarity of 0.499 g of NaOH dissolved in 150.00 mL of water is 0.082 M.
Molarity of a solution is defined as the number of moles of the solute present per litre of the solution. The unit of molarity is mol L⁻¹ and it is represented as 'M'.
Molarity = Number of moles of solute / Volume of solution in L
150.00 mL = 0.15 L

If you mixed three plastic cup's contents containing 0,05 L of IM Kool-Aid, 0.05 L of 2.5M Kool-Aid, and 0.05 L of 0.5M Kool-Aid, what would the molarity be of the resulting solution?
The resultant solution has a molarity of 1 M.
How to determine molarity?To find the molarity of the resulting solution, calculate the total amount of moles of Kool-Aid and the total volume of the solution.
The moles of Kool-Aid in each cup can be calculated as:
moles = concentration (M) × volume (L)
Cup 1: moles = 0.05 L × 0 M = 0 mol
Cup 2: moles = 0.05 L × 2.5 M = 0.125 mol
Cup 3: moles = 0.05 L × 0.5 M = 0.025 mol
The total amount of moles is:
total moles = moles in cup 1 + moles in cup 2 + moles in cup 3
total moles = 0 mol + 0.125 mol + 0.025 mol
total moles = 0.15 mol
The total volume of the solution is:
total volume = volume in cup 1 + volume in cup 2 + volume in cup 3
total volume = 0.05 L + 0.05 L + 0.05 L
total volume = 0.15 L
Now calculate the molarity of the resulting solution:
molarity = total moles ÷ total volume
molarity = 0.15 mol ÷ 0.15 L
molarity = 1 M
Therefore, the molarity of the resulting solution is 1 M.

What volume will 5.00 mol of an ideal gas occupy at 25.0 C. and 153 kPa of pressure?
Answer:
5.00 mol of an ideal gas will occupy 103.6 L at 25.0 C and 153 kPa of pressure.
Explanation:
Using the ideal gas law, PV=nRT, where P is the pressure, V is the volume, n is the number of moles of gas, R is the gas constant, and T is the temperature in Kelvin, we can solve for V.
First, we need to convert the temperature from Celsius to Kelvin by adding 273.15 K. Therefore, the temperature is 25.0 + 273.15 = 298.15 K.
Next, we can plug in the values we know:
PV = nRT
(153 kPa) V = (5.00 mol) (8.31 J/mol*K) (298.15 K)
Simplifying:
V = (5.00 mol) (8.31 J/mol*K) (298.15 K) / (153 kPa)
V = 103.6 L
Therefore, 5.00 mol of an ideal gas will occupy 103.6 L at 25.0 C and 153 kPa of pressure.

what is the starting concentration of the Cu+ solution
Luke needs to measure the iron (Fe) content of a 2.470 g steel sample. He starts by completely converting the iron in the steel to Fe2+ and dissolving it in 50.00 mL of water. Then, Luke determines the amount of Fe2+ by reacting it with a standardized aqueous 0.110 M potassium permanganate (KMnO4) solution.
MnO−4+8H++5Fe2+⟶Mn2++5Fe3++4H2O
The titration of the Fe2+ solution requires 39.23 mL KMnO4 solution to reach the end point. What is the percentage by weight of iron (Fe) in the steel sample?
The balanced equation for the reaction between [tex]Fe^+^2[/tex] and KMnO₄ is: MnO₄ + 8H+ + 5 [tex]Fe^+^2[/tex]⟶ [tex]Mn^+^2[/tex] + 5[tex]Fe^3^+[/tex] + 4H₂O. Therefore, the percentage by weight of iron in the steel sample is 1.94%.
Molarity of KMnO₄ = 0.110 M, Volume of KMnO₄ used = 39.23 mL = 0.03923 L
moles of [tex]Fe^+^2[/tex] = 0.110 M x 0.03923 L / 5 = 0.000856 moles
The mass of iron in the steel sample can be calculated from the number of moles of [tex]Fe^+^2[/tex]:
moles of Fe = 0.000856 moles [tex]Fe^+^2[/tex] x 1 mole Fe / 1 mole [tex]Fe^+^2[/tex]
= 0.000856 moles Fe
The mass of Fe can be calculated from the number of moles of Fe:
mass of Fe = 0.000856 moles Fe x 55.85 g/mol = 0.0479 g Fe
Finally, the percentage by weight of iron in the steel sample can be calculated as:
% Fe = (mass of Fe / mass of steel sample) x 100%
mass of steel sample = 2.470 g
% Fe = (0.0479 g / 2.470 g) x 100% = 1.94%

With work please
The first half-reaction is the oxidation of Cr2O7^2– to Cr^3+ and the second half-reaction is the reduction of I^– to IO3^–. When combined, the overall reaction is Cr2O7^2– + I^– → Cr^3+ + IO3^–.
The electrolytic cell consists of two electrodes, one anode and one cathode, both of which are immersed in an electrolyte solution. At the anode, the Cr2O7^2– ions are oxidized to Cr^3+ ions, releasing electrons into the external circuit.
At the cathode, the I^– ions are reduced to IO3^– ions, and the electrons from the external circuit are used to drive the reaction. The electrolyte solution must contain both Cr2O7^2– and I^– ions in order to facilitate the transfer of electrons between the electrodes.

When 1500J of energy is lost from a 120 gram object, the temperature decreased from 45° C to 40° C. What is the specific heat of the object?
Specific Heat = 2.5 J/g•°C
We can set up an equation to solve this.
(Energy) = (mass)•(specific heat)•(change in temperature)
Plug in what you know
-1500J = 120g•(c)•(40°C-45°C)
[The energy is negative because the energy is lost, and the change in temperature can be found by subtracting the initial temperature from the final temperature (T(Final) - T(Initial))]
Solve
-1500J = 120g•(c)•(40°C-45°C)
-1500J = 120g•(c)•(-5°C)
-1500J = (-600g•°C)•(c)
(-1500J) / (-600g•°C) = c

Menthol is a substance commonly used in cough drops. It has a molar mass of 156.3 g/mol and is comprised of 77.4% carbon and 12.9% hydrogen and 10.2% oxygen. The molecular formula is C[tex]_{10}[/tex]H[tex]_{20}[/tex]O.
The precise quantity and kind of atoms that make up a single chemical molecule are specified in its molecular formula. A compound's constituent elements are denoted by their chemical symbols, which are followed by numerical subscripts that indicate how many atoms of each constituent are contained in the molecule.
A molecular formula does not have a chemical name and is wordless. A molecular formula may suggest particular simple chemical structures, but it is not the same as a formula for the entire chemical structure. Compared to structural formulas, they are more restrictive.
moles of carbon =0.122/12=0.010
Moles of Hydrogen =0.0204/1=0.0204
moles of oxygen = 0.0171/16 =0.0017
Dividing by simple whole number ratio
The ratio of C : H : O = 10 : 20 : 1. The molecular formula is C[tex]_{10}[/tex]H[tex]_{20}[/tex]O.
