In which type of radioactive decay does the nucleus become more stable without changing its identity
During gamma decay, the nucleus become more stable without changing its identity.
The nucleus emits radiation during gamma decay without actually changing its makeup: We begin with a nucleus that contains 12 protons and 12 neutrons, and we finish with a nucleus that contains 12 protons and 12 neutrons. however, radioactivity escapes in the process.
When a nucleus has insufficient protons and too many neutrons, beta decay occurs (the neutron to proton ratio is too high). By converting a neutron into a proton and an electron, the nucleus becomes more stable. The beta particle is expelled quickly while the proton stays inside the nucleus.

The approximate pH of a 0.10 M solution of a weak acid with a Ka of 5x10-5 M is 4.8.
To calculate the approximate pH of a weak acid solution, we can use the Henderson-Hasselbalch equation, which states that pH = pKa + log([A-]/[HA]).
In this equation, [A-] is the concentration of the conjugate base and [HA] is the concentration of the weak acid. In this case, [HA] is 0.10 M and [A-] is 5x10-5 M.
Calculate the molarity of the weak acid:
Molarity = 0.10 m (given)
Calculate the Ka of the weak acid:
Ka = 5 x 10-5 m (given)
Calculate the concentration of the conjugate base:
Conjugate base concentration = Ka x molarity = 5 x 10-5 m x 0.10 m = 5 x 10-6 m.
Calculate the pH of the solution:

if the fourth shell (the n = 4 energy level) were shown, how many subshells would it contain?
The fourth energy level, or shell, would contain four subshells, designated s, p, d, and f.
What are subshells?
A subshell is a set of atomic orbitals with the same value of the angular momentum quantum number (l) and the same magnetic quantum number (m_l). Subshells are characterized by the letter s, p, d, f, etc., which corresponds to the value of l.
The fourth energy level, or shell, would contain four subshells, designated s, p, d, and f. The number of subshells in a given energy level is determined by the value of the principal quantum number (n).
Each subshell is designated by a letter, s, p, d, f, etc., which corresponds to the angular momentum quantum number (l). The value of l can be used to determine the number of subshells in a given energy level.
For example, l = 0 corresponds to an s subshell, l = 1 corresponds to a p subshell, l = 2 corresponds to a d subshell, and l = 3 corresponds to an f subshell. The principal quantum number of 4 shell is 4, so the value of l can be 0,1,2,3. Hence it contains 4 subshells.

2. What wave moves in a direction perpendicular to the force that created it?
Longitudinal wave
Reflected wave
Transverse wave
Interference wave
The transverse wave moves in a direction perpendicular to the force that created it. Therefore, option C is correct.
What is a transverse wave?Transverse waves can be defined as waves that oscillate perpendicular to the direction in which the wave is traveling forward. Examples of transverse waves involve electromagnetic waves, seismic S waves, and water surface ripples.
In a transverse wave, particles oscillate up and down w.r.t. mean location rather than following the path of its transmission.
A transverse wave can be demonstrated as where every particle of the medium travels about its mean location in a direction that is the opposite of the propagating.
Transverse waves can be formed in solids and on the surface of liquids. Transverse waves cannot be created in liquids or gases.

Answer: transverse wave
Explanation:
Suppose you are given a solution with 8.157 M sodium chloride dissolved in water. What volume, in mL, must you dilute to prepare a solution with a molar concentration of 2.733 M and a volume of 62.303 mL?
The concentration terms are molality, normality and mole fraction. Molarity can be used to find out the ionic strength of any solution. Therefore, volume of 8.157 M diluted solution of sodium chloride is 20.89ml.
What is molarity?
Molarity can be calculated by dividing number of moles of solute by volume of solution in litre. Molarity is affected by temperature. Its unit is mole/liter. It measure the concentration of any solute in a solution.
Mathematically,
According to the neutralization law,
M₁V₁=M₂V₂
where,
M₁ = molarity of stock solution = 1 M
V₁ = volume of stock solution = 250ml
M₂ = molarity of dilute solution =3M
V₂ = volume of dilute solution = ?
substituting all the given values we get
M₁V₁=M₂V₂
2.733 M×62.303 mL=8.157 M ×V₂
V₂=20.89ml
Therefore, volume of 8.157 M diluted solution of sodium chloride is 20.89ml.

One mole of an ideal gas does 3000 j of work on its surroundings as it expands isothermally to a final pressure of 1. 00 atm and volume of 25. 0 l. Determine the initial volume of the gas.
When 3000 joule work done on one mole of ideal gas isothermally the initial volume becomes 0.00765 m³.
An isothermal process, or one that occurs at a constant temperature, measures the work done on an ideal gas by
Work done w = 3000 joules
Pressure P = 1 atm = 1.013 x 105 N/m²
The final volume of the gas = 25 L = 25 x 10⁻³ m
w = n x P x V x ln(V₂/V₁)
3000J = 1 x ( 1.013 x 105 N/m² ) x ( 25 x 10⁻³ m³ ) x ln(0.025/V₂)
V₂= 0.00765 m³ of ideal gas in a container
Hence, the final volume of gas is more than the initial volume.

The initial volume of the gas would be 0.00765m³ when one mole of an ideal gas does 3000 j of work on its surroundings as it expands isothermally.
An isothermal process is a chemical or physical process during which the the temperature of the system remains constant while the transfer of heat from the system occurs so slowly that equilibrium state of system is maintained throughout.
The work done by ideal gas for an isothermal process is given by -
W = -nrt ln (vf/vi) = - [tex]P_{f} V_{f}[/tex] ln (vf / vi)
Thus
Vi = Vf exp (W / + Pf Vf )
(0.0250)exp [ -3000 / 0.0250(1.013 × [tex]10^{5}[/tex])]
= 0.00765m³

Jacob has a disk that sinks to the bottom when placed in a vessel of water. He cuts some holes in the disk and immerses it again in a vessel of water. Which of these is likely to happen?.
The disk will float on the surface of the water after making holes. The portion removed from the disk decreases the mass of the disk and becomes lighter.
The floating or sinking of the object is explained by Archimedes' principle. When the weight force on an object is countered by the water's upward push, the thing floats. Water exerts an upward force proportional to the volume of the submerged object. Water depth or volume has no bearing on this upward force. The object will sink if the downward force of the weight is greater than the upward force of the water on it. The thing will rise if the contrary is true because rising is the opposite of sinking.
Hence, upward force is applied on body based on water displaced by it.

The disc will now float at the top when Jacob makes some holes in it and puts it back in a container of water. So, A is the appropriate response to this question.
When the weight force on an object is countered by the water's upward push, the object floats. The amount of the object submerged increases with the water's upward push. Both the water's depth and volume have no bearing on it. According to the context of this question, a disc with no holes will undoubtedly sink to the bottom of the water due to its high density. However, when a hole is made in a disc, water is released from it, reducing the upward force and resulting in a lower density than before.
As a result, the disc will now float on top when Jacob makes some holes in it and puts it back in a water container. As a result, choice A is the right response to this query.

In a certain chemical reaction 5 g of chemical C are formed when 2 g of chemical A react with 3 g of chemical B. Initially there are 10 g of A and 24 g of B present, and after 5 min, 10 g of C has been produced. Determine the amount of C that is produced in 15 min
In a chemical reaction, one or more substances—also known as reactants—are changed into one or more additional substances—also known as products.
Chemical elements or chemical compounds make up substances. When atoms establish or break chemical bonds, chemical processes take place. Reactants are the substances that begin a chemical reaction, while products are the compounds that are created as a result of the reaction. Mass is conserved in a chemical reaction because the mass of the reactants before the reaction is equal to the mass of the products after the reaction, which results in the synthesis of new products. As a result, choice D is right.
