The covenant of further assurances requires the grantor to execute any necessary legal documents (within his power) necessary to fix title defects discovered after closing.

A warranty deed is typically signed by both parties when a seller transfers real estate to a buyer. According to Deed Claim, this document certifies that the seller is the legitimate owner of the property and is selling it free of any liens while transferring the legal title to the buyer. The assurances made by the seller are represented by the six covenants of title. Three covenants are regarded as existing covenants, and as such, they are applicable to the parties to the most recent transfer. The other three are future covenants, and if they are broken, any owner may bring a claim against any prior grantor.

Covenant of Seisin

The seller's rightful ownership of the property is guaranteed by the present covenant of seisin.

No Encumbrances

The seller guarantees that the property is possessed free and clear by making the current covenant against encumbrances.

Right to Convey

According to TheLaw.com, having the right to convey indicates that the seller is legally permitted to transfer the property to the buyer.

Quiet Enjoyment

The future covenant of quiet enjoyment guarantees that a third party's legal claim to title won't affect the buyer's right to possession.

Covenant of Warranty

The warranty covenant and the quiet pleasure covenant are extremely similar.

Further Assurances

This prospective covenant is a guarantee that, should the need ever arise, the grantor will take all reasonable steps to assist the grantee in perfecting the title.

Answer:

Explanation:.

The Hbr has highest boiling point followed by Kr , [tex]Cl_{2}[/tex] and [tex]F_{2}[/tex] .

The Hbr has  highest boiling point due to presence of intermolecular H-bonding that is hydrogen bonding.

The electronegativity of bromine is greater than hydrogen atom. The electronegativity difference hydrogen atom and bromine atom is high. So, due to this a positive dipole is generated at hydrogen atom and partial negative charge, these partial charge is called dipole. In a HBr molecule one H-atom attracted by Br-atom of another atom by force of attraction and this partial force of attraction is called H-bonding.

The visuals might be pictures (from a television or computer display), electrical waveforms (from an oscilloscope), radar targets, or other occurrences.

Tomson came to the conclusion that atoms can be divided into their constituent corpuscles (atoms are made up of smaller particles).

The electron was discovered in 1897 by J. J. Thomson.

Sigma bonds are the most powerful type of covalent chemical link. They are generated by atomic orbitals overlapping head-on. For diatomic molecules, sigma bonding is most readily explained using the language and tools of symmetry groups.

Chemical covalent bonds are sigma bonds and pi bonds. The overlap of atomic orbitals creates sigma and pi bonds. Sigma bonds are produced by overlapping from end to end, whereas Pi bonds are created when the lobe of one atomic orbital overlaps another.

When an electron in a quantum system drops from a higher energy level to a lower one, the system emit a photon.

The energy of the electron drops when it transitions levels, as well as the atom releases photons. The emission of the photon occurs as the electron transitions from an energy state to a lower state. The photon energy represents precisely the energy that would be lost when an electron moves to a level with less energy.

When such an excited electron transitions from one energy level to another, this could emit a photon. The energy drop would be equivalent to the power of the photon that is released. In electron volts, the energy of an electron, as well as its associated photon (emitted or absorbed) has been stated.

Answer:

Explanation:

from the equation:

4Fe + 3O2 -----> Fe2O3

the mole ratio of Fe to O2 follows,

3 moles O2 reacts with 4 moles Fe.

therefore,

1 mole O2 reacts with 4/3 moles Fe

and 12 moles O2 reacts with (4/3) × 12 moles Fe = 16 moles

Answer:

9.0 moles of O2 and produce 6.0 moles of Fe2O3

Explanation:

Fe→Fe3++3e− iron. Is oxidised: it's losing electrons

O2+4e−→2O2− oxygen Is reduced, it's gaining electrons

Balance for the electrons.

The smallest common product of 3 and 4 Is 12.

So we get:

4Fe→4Fe3++12e−

3O2+12e−→6O2−

Adding:

4Fe+3O2+12e−→4Fe3++12e−+6O2−

The electrons balance so they cancel out:

4Fe+3O2→4Fe3++6O2−

Since Fe and O can combine in a ratio of 2:3

4Fe+3O2→4Fe3++6O2−→2Fe2O3

The "break-even" interest rate for year n that equates the return on an n-period zero-coupon bond to that of an n - 1 - period zero-coupon bond rolled over into a one-year bond in year n is defined as the forward rate.

A forward rate is a specified price agreed by all parties involved for the delivery of a good at a specific date in the future. The use of forward rates can be speculative if a buyer believes the future price of a good will be greater than the current forward rate. Alternatively, sellers use forward rates to mitigate the risk that the future price of a good materially decreases.

Regardless of the prevailing spot rate at the time the forward rate meets maturity, the agreed-upon contract is executed at the forward rate. For example, on January 1st, the spot rate of a case of iceberg lettuce is $50. The restaurant and the farmer agree to the delivery of 100 cases of iceberg lettuce on July 1st at a forward rate of $55 per case. On July 1st, even if the price per case has decreased to $45/case or increased to $65/case, the contract will proceed at $55/case.

A liquid, solid, or gas's volume represents the amount of three-dimensional space it occupies. Although there are many additional units that can be used to indicate volume, the most used ones are liters, cubic meters, gallons, milliliters, teaspoons, as well as ounces.

Given data :

Mass of [tex]O_{2}[/tex] = 1.20 g

Mass of [tex]N_{2}[/tex] = 1.43 g

Number of moles can be calculated by suing the formula:

Number of moles of [tex]O_{2}[/tex] = Mass / molar mass = 1.20 / 32 = 0.03 mol

Number of moles of [tex]N_{2}[/tex] =  Mass / molar mass  = 1.43 / 28 = 0.05 mol

So, the total count of moles can be calculated by :

Total moles = moles of [tex]O_{2}[/tex]  +  moles of [tex]N_{2}[/tex]

Total moles = 0.03  + 0.05 = 0.08 mol

The volume of the gas at STP can be calculated as:
