Answer:

The moon's gravity pulls at the Earth, causing predictable rises and falls in sea levels known as tides. To a much smaller extent, tides also occur in lakes, the atmosphere, and within Earth's crust. High tides are when water bulges upward, and low tides are when water drops down.

Answer:

Gravity is dependent on the mass of two bodies and the distance between them. There is a strong gravitational attraction between Earth and the Moon because they’re relatively close to one another. There is a strong gravitational attraction between Earth and the Sun because the Sun is so massive.

Explanation:

Please note this is the answer to a TWO part question, ONE being the Earth and the MOON the other being the EARTH AND SUN

Direct electron transfer from a singlet reduced species to a triplet oxidizing species is quantum-mechanically forbidden

posledela

Direct electron transfer from a a singlet reduced species to a triplet oxidizing species is quantum-mechanically forbidden.

<h3><u>Transfer from singlet to triplet:</u></h3>

Either an excited singlet state or an excited triplet state will occur when an electron in a molecule with a singlet ground state is stimulated (through radiation absorption) to a higher energy level.
All electron spins in a molecule electronic state known as a singlet are coupled.
In other words, the ground state electron and the stimulated electron's spin are still coupled (a pair of electrons in the same energy level must have opposite spins, per the Pauli exclusion principle).
The excited electron and ground state electron are parallel in a triplet state because they are no longer coupled (same spin).
It is less likely that a triplet state would arise when the molecule absorbs radiation since excitation to a triplet state necessitates an additional "forbidden" spin transfer.

If a beaker of water and a beaker of acetic acid are at the same elevated temperature, which will cool more quickly to room temp

4vir4ik [10]

The beaker of acetic acid will cool more quickly.

The specific heat capacity of acetic acid is about half that of water.
Thus, it takes twice as much heat gain (or loss) in acetic acid to cause a given change in temperature.
If everything else is constant and heat is being lost at the same rate, the temperature of the acetic acid should drop twice as fast as that of water.

Based on the activity series provided, which reactants will form products? F > Cl > Br > I CuI2 Br2 Right arrow. Cl2 Al

AleksAgata [21]

The reactants based on the reactivity capable of forming the products are $\rm CuI_2\;and\;Br_2$ . Thus, option A is correct.

The reactivity series has been the arrangement of the elements based on their reactivity. The highly reactive element has been capable of replacing the less reactive element in the compound, and form the product.

In the following reactions, the new product has been formed by:

$\rm CuI_2\;and\;Br_2$

From the reactivity series, Br has been more reactive than I, and thereby replaces iodine in the compound for the formation of product.

$\rm Cl_2\;and\;AlF_3$

The compound has been formed with F. Cl has been less reactive than F, and will not be able to form the product.

$\rm Br_2\;and\;NaCl$

The compound has been formed with Cl. Br has been less reactive than Cl, thus will not displaces Cl for the formation of new product.

$\rm CuF_2\;and\;I_2$

The compound has been formed with F. I has been less reactive than F, and will not be able to form the product.

The reactants that will be able to form the products have been $\rm CuI_2\;and\;Br_2$ . Thus, option A is correct.
