5. Write a nuclear equation for the alpha decay of 249-101Md.
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.
The pressure of 134 mL of a sample of carbon dioxide is increased from 485 mm Hg to 1,222 mm Hg. Calculate the new volume of the carbon dioxide.
The new volume of a gas when the pressure is increased is 53.2 mL.
What is the new volume of a gas when the pressure is increased?The new volume of a gas when the pressure is increased is determined using the formula from Boyle's law given below:
P₁V₁ = P₂V₂

A: 7.2
The initial speed of a tennis ball is 53.6 m/s and the launch angle is theta =21 degrees.
When a tennis ball strikes the ground, how much speed does it lose?The serve speeds displayed on courtside digital monitors are calculated as soon as the ball exits the racquet. Fortunately for returners, by the time the ball reaches them, air resistance and court surface friction have reduced its speed by around 50%.
The tennis ball must subsequently bounce to a height of between 135 cm and 147 cm, implying a velocity of between 5.14 m/s and 5.36 m/s when it leaves the ground, according to the rules.
Average speed is calculated by dividing the total distance traveled by the body by the time required to cover that distance.

a hot and concentrated solution of kbr was slowly cooled down to facilitate the crystallization of kbr, as the kbr crystals grew, the entropy of the system (the mixture of water and kbr) will group of answer choices stay the same decrease there is not enough information. increase
As the KBr crystals form from the hot and concentrated solution, the entropy of the system decreases. This is because the process of crystal formation is an ordered process, leading to a decrease in the number of available microstates, thus reducing entropy. As the solution cools, the solute molecules slow down and start to arrange themselves into a highly ordered lattice structure, which results in the formation of KBr crystals. This decrease in entropy is compensated by an increase in the entropy of the surroundings, such as the air or the container, in order to maintain the overall increase in entropy required by the second law of thermodynamics.

The light colored panel reflects light and heats up, while the dark colored panel absorbs the light and stays cooler. This temperature difference causes the vanes to spin.
Describe how the light and dark colored panels affect how the radiometer spins.The dark panel absorbs the incoming light, while the light panel reflects it. Due to this, the two panels' temperatures differ, with the dark panel becoming hotter than the light panel.
Due to the pressure difference caused by the temperature difference, air molecules move from the hot, dark panel to the cool, light panel. The radiometer's associated vanes spin as a result of this air flow.

Which of the following represents an electron configuration that corresponds to the valence electrons of an element for which there is an especially large jump between the second and third ionization energies? (Note: n represents a principal quantum number equal to or greater than 2.)
answer choices
O ns2
O ns2np1
O ns2np2
O ns2np3
The answer is O ns2np2. This electron configuration corresponds to the valence electrons of an element for which there is an especially large jump between the second and third ionization energies.
The number of electrons in the outermost shell, or valence shell, is equal to the principal quantum number (n) squared (2 x 2 = 4), plus two additional electrons (2). So the total number of electrons in the valence shell is 6.
Electron configuration is the arrangement of electrons in the shells of an atom. It is an important concept in chemistry, as it is related to the atom's reactivity and how it interacts with other atoms. Electron configuration can be described in terms of the orbital notation, which uses the quantum numbers of an electron to describe which orbitals it occupies. Electron configuration can also be described in terms of electron subshells, which are groups of orbitals with the same principal quantum number.

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.

The heat of solution is the total enthalpy change when a solution is formed from the separated solute and solvent is true statement.
It is true that the overall enthalpy change that occurs when a solution is created from a separated solute and solvent is known as the heat of solution. The change in enthalpy that occurs when 1 mol of solute (component 1) dissolves in a solvent is known as the enthalpy of solution (or heat of solution) (component 2).
The amount of heat that can be emitted or absorbed when a solution dissolves is simply referred to as the enthalpy change of the solution. At a constant temperature, the enthalpy of a solution is typically represented as kJ/mol.
Three essential steps are necessary for the enthalpy of a solution:
1. Solute separation: This is the breakdown of the solute. The solute is no longer held together by any intramolecular forces in this situation.
2. Solvent separation: This occurs when all intramolecular forces holding the solvent together are broken as a result of the breakdown of the solvent.
