The gravitational force is the universal force of attraction, which is acting between objects.

Its work integral over any given trajectory joining the points A and B yields the same result. Hence, it can be associated with a potential function. The gravitational potential energy between point masses m1 and m2 separated by a distance r is,

E = -G x m1m2/r

The moon orbits the planet with an orbital radius d The total energy in the orbit equals, E= Egp + K.

The sum of the gravitational potential energy and the kinetic energy due to its circular motion.

the gravitational force exerted by the planet on the moon equals the product of the moon's mass and the centripetal acceleration.

Substituting the force and the centripetal acceleration,

G* Mm/ d2=mv2 *d

.

The squared velocity is then given as ,

v^2 = G* M/ d

Substituting this result in the kinetic energy,

K =1/2 *mv^2 =1/2 * G* Mm/d

.The total energy is then, -\(\frac{1}{2} G\frac{Mm}{d}\).

The compounds ranked by their expected lattice energy from greatest to least are: MgF_2, MgCl_2, MgBr_2, MgI_2.

Lattice energy is a measure of the energy released when gaseous ions come together to form an ionic solid. It is influenced by factors such as ion charge and ion size. In general, as the charges of the ions increase, the lattice energy also increases. However, when comparing ions with the same charge, the size of the ions becomes the determining factor.

In the given compounds, the common ion is Mg_2+ (with a +2 charge), while the anions are F-, Cl-, Br-, and I-. Among these anions, fluoride (F-) has the smallest ionic radius, followed by chloride (Cl-), bromide (Br-), and iodide (I-). Smaller ions have a higher charge density, meaning the positive charge is concentrated in a smaller space, leading to stronger attractive forces between the ions.

Therefore, based on ion size, the compound with the greatest expected lattice energy is MgF_2, followed by MgCl_2, MgBr_2, and MgI_2, with MgF_2 having the strongest bond and MgI_2 having the weakest bond.

Balanced chemical equation:

\(3 Ba(NO3)2 (aq) + 2 K3PO4 (aq) ----- > 6 KNO3 (aq) + Ba3(PO4)2(s)\)

What is double-displacement reaction?

In an aqueous solution, a double-displacement reaction takes place when the positive and negative ions of two ionic compounds exchange positions to form two completely different compounds.

Chemical formula for :

Barium nitrate---> Ba(NO3)2  (aq)

Pottasium Phosphate = K3PO4 (aq)

Reaction between these two is a type of double displacement type reaction in which ions are exchanged , forming

Pottasium Nitrate -----> KNO3 (aq)

Barium Phosphate -----> Ba3(PO4)2 (s)

(aq) means the phase is aqueous and (s) means phase is solid or the compound precipitated out .

Now, writing the molecular formula using the above data , we get:

\(Ba(NO3)2 (aq) + K3PO4 (aq) ------ > KNO3 (aq) + Ba3(PO4)2 (s)\)

A equation is called balanced when number of chemical species are same on both sides of the equation .

Here, in product side there are 3 Ba and 2 (PO4) and only 1 Ba and 1 PO4 in reactant side to balance this let's multiply

2 with K3PO4 on reactant side and ,

3 with Ba(NO3)2 on reactant side

The equation thus becomes:

\(3 Ba(NO3)2 (aq) + 2 K3PO4 (aq) ------ > KNO3 (aq) + Ba3(PO4)2 (s)\)

Now,

There are 6 K atoms on reactant side to balance this let's multiply 6 with KNO3 in product side by doing so we also balanced NO3.

Consequently, the balanced chemical equation is

3 Ba(NO3)2 (aq) + 2 K3PO4 (aq) ----- > 6 KNO3 (aq)  + Ba3(PO4)2(s)

A delocalized π bond is a π bond which is spread over more than two atoms.

A delocalized π bond can exist where π bonds are separated by more than one single bond. The most famous example of delocalized π bonds is benzene. The species that contains a delocalized π bond is Benzene, C6H6.

                             This is because the electrons in the π bond are spread out over all of the six carbon atoms in the benzene ring, making it a delocalized π bond rather than a localized π bond.

                                    The delocalization of the π electrons stabilizes the molecule, making it more difficult to break apart. It is also responsible for the characteristic stability of benzene, which is why it is so commonly used in organic chemistry. Hence, the detailed answer is Benzene.

The key special chemical used by chemosynthetic communities at salt seeps is hydrogen sulfide (H2S).

Chemosynthetic communities are biological communities that are supported by chemical energy rather than sunlight. These communities are found in environments such as deep-sea hydrothermal vents, cold seeps, and salt seeps, where there is no sunlight available for photosynthesis. Instead, chemosynthetic organisms use chemical energy to produce organic matter.

In the case of salt seeps, the key chemical used by chemosynthetic communities is hydrogen sulfide (H2S). Hydrogen sulfide is produced by the decomposition of organic matter in the sediments, and it diffuses up into the overlying seawater. Chemosynthetic bacteria, such as sulfur-oxidizing bacteria, use hydrogen sulfide as their energy source in a process called chemosynthesis.

During chemosynthesis, bacteria use the energy from the oxidation of hydrogen sulfide to convert carbon dioxide and water into organic matter. This organic matter serves as the basis of the food chain for other organisms in the community, such as tube worms, clams, and mussels. These organisms in turn provide food for larger animals such as fish, crabs, and sea stars.

The chemosynthetic process is similar to photosynthesis in that both processes produce organic matter. However, photosynthesis uses light energy to power the process, while chemosynthesis uses chemical energy. Chemosynthetic communities are important in deep-sea ecosystems, as they provide the foundation for the food chain in environments where sunlight is not available.

The percent yield shows the extent to which the reactants are converetd into products . The limiting reactant is used up in the reaction.

A limiting reactant is the reactant that is in the least amount in the system.  Now;

Number of moles of Fe =  12.21 g/56 g/mol = 0.22 moles

Number of moles of O2 = 13.54 g/32 g/mol = 0.42 moles

Balanced reaction equation;

3Fe(s) + 2 O2(g) = Fe3O4(s)

If 3 moles of Fe reacts with 2 mole of O2

0.22 moles of Fe reacts with  0.22 moles * 2 mole/3 moles = 0.15 moles

Hence, Fe is the limiting reactant

If 3 mole of Fe produces 1 mole of  Fe3O4(s)

 0.22 moles  of O2   produces   0.22 moles * 1 mole/3 moles of  Fe3O4(s) = 0.1073 moles

Mass of  Fe3O4(s) =0.1073 moles  * 232 g/mol =16.9 g

Number of moles of excess reactant = 0.42 moles - 0.15 moles = 0.27 moles

Mass of excess reactant = 0.27 moles * 32 g/mol = 8.64 g

Decreasing the TBCl concentration will not affect the rate constant in this experiment. The rate constant is determined by the specific reaction and temperature conditions and is independent of the reactant concentrations.

The rate constant (k) is a proportionality constant that relates the rate of a reaction to the concentrations of the reactants. However, the rate constant itself is not affected by the concentrations of the reactants. It is determined by the specific reaction and temperature conditions.

The rate of a chemical reaction can be expressed using the rate equation, which typically includes the concentration terms for the reactants raised to certain powers.

These powers, known as reaction orders, can be determined experimentally. However, the rate constant is a separate factor in the rate equation and is not dependent on the reactant concentrations.

By decreasing the TBCl concentration, the rate of the reaction may be affected, as the rate is directly proportional to the reactant concentrations.

However, the rate constant itself remains unchanged. The rate constant is influenced by factors such as temperature, presence of catalysts, and the nature of the reacting species, but not by the concentrations of the reactants.

Therefore, decreasing the TBCl concentration will not affect the rate constant in this experiment.
