The nuclear equation for the alpha decay of Uus-294 is

\(^{294}{117} Uus\) →\(^{4}{2}He + ^{290}_{115}Mc\)

To complete the nuclear equation for the alpha decay of Uus-294, we need to determine the missing product.

During alpha decay, the emission of an alpha particle, composed of two protons and two neutrons, leads to the formation of a new nucleus.

The balanced nuclear equation for the alpha decay of Uus-294 can be represented as follows:

\(^{294}{117} Uus\) → \(^{4}{2}He +\)_____(missing product)

In this equation, the atomic number of the missing product must be two less than the atomic number of Uus-294 (117 - 2 = 115), and the mass number of the missing product must be four less than the mass number of Uus-294 (294 - 4 = 290).

Based on this information, the missing product can be identified as:

\(^{290}_{115}Mc\)

Mc stands for Moscovium, which has an atomic number of 115. By subtracting two from the atomic number of Uus, we obtain the atomic number of Mc. The mass number of Mc-290 is obtained by subtracting four from the mass number of Uus-294.

When filling a buret for a titration, first adjust the buret in the clamp so that it is vertical. Then, choose an appropriate funnel to add the titrant into the buret. The titrant should be filled to just above the zero mark on the buret, and the buret tip should be briefly opened to remove any bubbles.

After that, the buret can be adjusted to the desired volume and the titration can proceed. It is important to take note of the initial buret reading before starting the titration to ensure accurate measurement of the titrant volume.

When filling a buret for a titration, it is important to first adjust the buret in the clamp so that it is vertical and its tip is below eye level to ensure accurate volume measurements. Next, choose an appropriate method to add the titrant into the buret, such as using a funnel or a pipette.

It is important to avoid splashing or spilling the titrant to ensure accurate and precise measurements. The titrant should be filled above the zero mark on the buret and then slowly drained until the bottom of the meniscus is aligned with the zero mark.

This process is called "buret priming" and it helps to remove any air bubbles from the buret tip that can affect the accuracy of the measurements. Once the buret is primed and filled with the titrant, it is ready to be used for the titration.

The valence-shell configuration of the metallic element M in Period 4 is 4s2 4p6.

What is the valence-shell configuration of the metallic element M in Period 4?

The valence-shell configuration refers to the arrangement of electrons in the outermost shell, or valence shell, of an atom. In Period 4, the valence shell of the metallic element M would be the fourth shell, denoted as the 4s and 4p orbitals.

The electron configuration of an element is determined by the position of the element in the periodic table. Since M is in Period 4, we know that it has four electron shells. The valence electrons are those located in the outermost shell, which determine the element's chemical properties and reactivity.

In this case, the valence-shell configuration of M is given as 4s2 4p6, indicating that there are two electrons in the 4s orbital and six electrons in the 4p orbitals. The total number of valence electrons can be calculated as the sum of the electrons in the valence orbitals, which in this case is 8.

the final volume of air in the balloon  when the balloon is taken to a depth of 10ft in a swimming pool, where the pressure is 981 torr is 10.8 L. Answer: d) 10.8 L.

We are given the initial volume of air in the balloon, Vi = 14.0 L. The initial pressure, Pi = 760 torr. The final pressure, Pf = 981 torr. The depth of the swimming pool, h = 10 ft. The temperature of the air, T is constant, which means that the gas in the balloon is an ideal gas.

We can use Boyle's law and the pressure difference to find the final volume of air.Boyle's law states that at a constant temperature, the volume of a gas is inversely proportional to its pressure. That is,V_1/P_1 = V_2/P_2where V1 and P1 are the initial volume and pressure, and V2 and P2 are the final volume and pressure.

Rearranging this equation, we getV_2 = V_1 × P_1/P_2= 14.0 L × (760 torr)/(981 torr)= 10.8 L

Therefore, the final volume of air in the balloon is 10.8 L. Answer: d) 10.8 L.

Answer:

ionic radii of elements increases down the group

Explanation:

Although at ionic state elements acquire noble gas configuration, there is an extra energy level down the group.

This leads to a decrease in attraction between electrons and the nucleus down the group.

For advanced level

Down the group an extra energy level creates screening of the penultimate shell decreasing the effective nuclear charge.

This leads to increase in the radius

Answer:

Calcium has a smaller radius in comparison to Potassium.

Explanation:

When we move down a group, the atomic radius increases, and when we move from left to right in a period, the atomic radius decreases. Since both Potassium and Calcium are in the 4th period, we have to look left to right. Calcium is to the right of Potassium making the radius smaller.

The initial concentration of 'A' was approximately 1.371 M.

To determine the initial concentration of 'A' given the reaction rate constant, time, and the remaining amount of 'A', you can use the integrated rate law equation for a first-order reaction:

[A]t = [A]₀ * e^(-kt)

where:
[A]t = concentration of 'A' at time t (0.048 M)
[A]₀ = initial concentration of 'A'
k = reaction rate constant (0.012 M⁻¹ s⁻¹)
t = time in seconds (27 minutes = 27 * 60 = 1620 seconds)

Now, let's solve for [A]₀:

0.048 M = [A]₀ * e^(-0.012 M⁻¹ s⁻¹ * 1620 s)

To find [A]₀, divide both sides by e^(-0.012 * 1620):

[A]₀ = 0.048 M / e^(-0.012 * 1620)

Now, calculate the value:

[A]₀ ≈ 0.048 M / e^(-19.44)

[A]₀ ≈ 0.048 M / 0.000035

[A]₀ ≈ 1.371 M

So, the initial concentration of A was approximately 1.371 M.

The formula for the time (t) it will take for perfume molecules to diffuse a distance (l) into the room can be derived as follows: t = (l^2) / (6D), where D is the diffusion coefficient.

Diffusion is the process by which molecules spread out from an area of high concentration to an area of low concentration. In this case, we are considering the diffusion of perfume molecules into the room. To derive a formula for the time it takes for diffusion to occur, we need to consider the factors that affect the rate of diffusion.

The time it takes for molecules to diffuse a distance (l) can be related to the diffusion coefficient (D), which is a measure of how quickly molecules move and spread out. The formula for the time (t) can be derived using the equation t = (l^2) / (6D), where (l^2) represents the squared distance traveled and 6D represents the diffusion coefficient.

The diffusion coefficient depends on various factors, including the mass (m) and collision cross-section (σ) of the perfume molecules, as well as the pressure (p) and temperature (t) of the environment. By assuming that the mass and collision cross-section of the perfume molecules are similar to air molecules, we can consider them to be constant in the formula.

It's important to note that this derived formula is a simplification and assumes ideal conditions. Real-world diffusion processes may involve additional factors and complexities. However, the derived formula provides a starting point for understanding the relationship between diffusion time, distance, and the diffusion coefficient.

One example of a naturally occurring radioactive isotope is uranium-238 (U-238).

Uranium-238 (U-238) is a radioactive isotope that exists in nature. Its half-life is approximately 4.5 billion years. U-238 undergoes a decay process called alpha decay, where it emits an alpha particle consisting of two protons and two neutrons. The daughter product of U-238 decay is thorium-234 (Th-234), which is also radioactive with a half-life of about 24 days. Th-234 further decays into protactinium-234 (Pa-234) through beta decay.

The decay chain continues until it reaches a stable isotope, lead-206 (Pb-206). The daughter products of U-238 decay are unstable and undergo further radioactive decay until a stable isotope is reached.

1. Formulae of hydrate is Na₂CO₃.10H₂O

2. Formulae of hydrate is CaSO₄.2H₂O

Explanation:

Q1. Mass of hydrated salt = 8.50 g mass

mass of anhydrous salt = 7.26 grams

mass of water lost = 1.24

Formula of hydrated salt = Na₂CO₃.xH₂O

Formula of anhydrous salt = Na₂CO₃

Molar mass of anhydrous salt is obtained as below where Na = 23, C = 12, O = 16, H = 1

Molar mass of Na₂CO₃ = (23 *2 + 12 + 16 * 3) = 106 g

molar mass of water = (1 *2 + 16) = 18 g

Mole ratio of Na₂CO₃ to H₂O = 7.26/106 : 1.24/18

Mole ratio of Na₂CO₃ to H₂O = 0.0068 : 0.068

Mole ratio of Na₂CO₃ to H₂O = 1 :10

Therefore, formulae of hydrate is Na₂CO₃.10H₂O

Q2.  Mass of hydrated salt = 60.98 g mass

mass of anhydrous salt = 48.23 grams

mass of water lost = 12.75

Formula of hydrated salt = CaSO₄.xH₂O

Formula of anhydrous salt = CaSO₄

Molar mass of anhydrous salt is obtained as below where Ca = 40, S = 32, O = 16, H = 1

Molar mass of CaSO₄= (40 + 32 + 16 * 4) = 136 g

molar mass of water = (1 *2 + 16) = 18 g

Mole ratio of CaSO₄ to H₂O = 48.23/136 : 12.75/18

Mole ratio of CaSO₄ to H₂O = 0.35 : 0.70

Mole ratio of CaSO₄ to H₂O = 1 : 2

Therefore, formulae of hydrate is CaSO₄.2H₂O

Explanation:

Question 3:

Mass of anhydrous compound = 7.26g

Mass of water = 8.50 - 7.26 = 1.24 g

Percentage of water of crystallization in the compound is = (1.24 / 8.50) * 100 = 14.59%

The mass ratio of Na2CO3 : H2O = 7.26 : 1.24

Using mole = mass / molar mass;

The mole ratio of  Na2CO3 : H2O = 7.26 /105.99  : 1.24 / 18 = 0.069 : 0.069 or 1 : 1

The formular is; Na2CO3.H2O

Question 4:

Mass of anhydrous compound = 48.23 g

Mass of water = 60.98 - 48.23 = 12.75 g

Percentage of water of crystallization in the compound is = (12.75 / 60.98) * 100 = 20.91%

The mass ratio of CaSO4 : H2O = 48.23 : 12.75

Using mole = mass / molar mass;

The mole ratio of  CaSO4 : H2O = 48.23 / 136.14 : 12.75 / 18 = 0.3543 : 0.708 which is 1 : 2

The formular is; CaSO4.2H2O
