This is a precipitation reaction and 1.38 g of the precipitate will be formed is the statement is correct. Hence, option C is correct.
What is a precipitation reaction?A precipitation reaction is when two or more dissolved chemicals combine to form one solid products. The exchange of ions between ionic compounds in aqueous solutions is a common component of these reactions, which are also occasionally referred to as double displacement, double replacement, or metathesis reactions.
in response to precipitation a process that converts soluble salts into solids that are insoluble in water. a neutralizing response an interaction between an acid and a base that results in the production of salt, water, and an ionic molecule.
Precipitate refers to a solid that forms from a solution. The blending of two transparent solutions is a common example: NaCl in combination with silver nitrate The answer is. The soli cannot be dissolved in water.

The Thermal Energy
The thermal energy of an object is the total kinetic energy of its particles. An object's
thermal energy depends on the mass of the object, its temperature, its state of matter,
and its chemical composition. Larger objects have more thermal energy than smaller
objects of the same material and density at the same temperature. A liquid substance
has more thermal energy than the same mass of the substance in its solid form.
9. Suppose you have two identical objects made of the same mass of the same material.
If one object is 20 °C warmer than the other, which object has more thermal energy?
Thermal Energy is directly proportional to the temperature
Or
[tex]\\ \sf\longmapsto Thermal\: Energy\propto Temperature [/tex]
So if temperature increases the thermal Energy also increases.
An object which is 20°C warmer than other has more thermal energy
ssignment (1) Nitrobenzene has a dipole moment of 4.2 x 10-9 esu cm while phenol has a value of only 1.7 x 10-8 esu cm. However, nitrobenzene is soluble only to the extent of 0.0155mole/kg in water while phenol is soluble to the extent of 0.95mole/kgat 20C. explain this phenomenon.
Phenol can form hydrogen bonds with water since it contains O-H group but nitrobenzene can not form hydrogen bonds with water.
Polar molecules tend to be soluble in water. The greater the dipole moment, the greater the polarity of the compound. We can see that Nitrobenzene has a dipole moment of 4.2 x 10-9 esu cm while phenol has a dipole moment of 1.7 x 10-8 esu cm.
Now, It is confusing to observe that the solubility of Nitrobenzene in water is far less than that of phenol despite its higher dipole moment. The reason for this observation is that, phenol can form hydrogen bonds with water since it contains O-H group but nitrobenzene can not form hydrogen bonds with water.
Therefore, phenol is more soluble in pure water as a solvent compared to nitorbenzene.

During the 1800s in England, relations police, which became composed of male volunteers, became organised to observe the protection and protection of their relatives.
What is protection?Protection is any measure taken to guard a thing against damage.
During the 1800s in England, relations police, which became composed of male volunteers, became organised to observe the protection and protection in their relatives.
As Britain's populace step by step expanded, so did the number of crimes that had been committed. This intended that regulation and order additionally needed to improve.
The New York City Police Department (NYPD) originates withinside the Government of New York City and tries to manipulate growing crime in early to mid-nineteenth century New York City.
This expanded crime became because of an expanding populace, brought about usually through negative Irish immigrants starting withinside the 1820s.
Whereas, as societies have become greater heterogeneous and complex, the function of the police is turning greater demanding. To fulfil this function, law enforcement officials want numerous broadly acknowledged competencies and private qualities, however much less is thought approximately how they're valued through police recruits.
Thus, we've tested the perspectives of police recruits in six European nations on 3 skills or traits of regarded significance for police work: knowledge, leadership, and the cap potential to shape precise family members with residents.
We have additionally explored versions in perspectives of recruits in distinct businesses and modifications of their perspectives for the duration of their schooling. For those purposes, we used survey facts accumulated withinside the RECPOL project.

Which group is composed entirely of nonmetals?
Answer:
These are the nonmetals.
Zingerone, one of the flavor molecules in ginger,
contains only C, H, and O. Combustion of 10.0 g
of zingerone produces 24.91 g of CO2 and
6.522 g of H20. Determine the molar mass of the
compound if it is between 150.0 and 220.0 g/
mol. Provide an answer to four significant
figures.
The molecular formula of the compound is C12H15O3 hence the molar mass of the compound is 207 g/mol.
We need to obtain the number of moles of carbon, hydrogen and oxygen in the compound;
Carbon = 24.91 g/44g/mol × 1 mole of carbon = 0.566 moles
Mass of carbon = 0.566 moles × 12 g/mol = 6.792 g
Number of moles of hydrogen = 6.522 g/18 g/mol × 2 moles = 0.725 moles
Mass of hydrogen = 0.725 moles × 1 g/mol = 0.725 g
Mass of oxygen = 10 - (6.792 g + 0.725 g) = 2.483 g
Number of moles of oxygen = 2.483 g/16 g/mol = 0.155 moles
Now we must divide through by the lowest number of moles;
C - 0.566/0.155 H - 0.725/0.155 O - 0.155/0.155
C - 4 H - 5 O - 1
The simplest formula is C4H5O Recall that the molar mass of the compound lies between 150.0 and 220.0 g/mol
4(12) + 5(1) + 16 = 69
Hence; n = 3 and the molecular formula of the compound is C12H15O3
The molar mass of the compound is; 12(12) + 15(1) + 3(16) = 207 g/mol
