The reaction starts with Anisole which is ortho-para directing group. So reacting anisole with Con H2SO4 and con HNO3 gives paranitro anisole.

Now paranitro anisole is a meta directing group and having low electron density in meta position which on reacting with Cl2 and anh AlCl3 directs the chlorine to meta position of nitro group and results in formation of the product 2-chloro-4-nitroanisole.

Thus, the product is 2-chloro-4-nitroanisole

The response begins with Anisole which is ortho-para coordinating gathering. So responding anisole with Con H2SO4 and con HNO3 gives paranitro anisole.  

Further Explanation:  

Presently paranitro anisole is a meta coordinating gathering and having low electron thickness in meta position which on responding with Cl2 and anh AlCl3 guides the chlorine to meta position of nitro gathering and results in development of the item 2-chloro-4-nitroanisole. Subsequently, the item is 2-chloro-4-nitroanisole.  

Mono substituted benzene:  

A particle or practical gathering where just a single hydrogen has been supplanted by another molecule or gathering. These substituents are not restricted to methyl bunches as appeared here. When thinking about alkene strength, just carbon substituents matter (i.e., - CH3 or - Ph matter however - Br or - OCH3 don't). Benzene.  

Mono substituted Benzene Derivatives:  

For those substituent bunches which are named distinctly with prefixes, frequently the prefix is connected to the parent name in the manner we have turned out to be utilized to.  In the event that the benzene ring is on a carbon bind which is utilized to shape the root name, at that point the benzene ring utilizes the prefix: phenyl.

Which family on the periodic table has a filled outer energy level?
Ede4ka [16]

The family on the periodic table that has a filled outer energy level is VIIIA. The answer is letter D. They are also called the noble gases or inert gases. They are virtually unreactive towards other elements or compounds. They are found in trace amounts in the atmosphere. Their elemental form at room temperature is colorless, odorless and monatomic gases. They also have full octet of eight valence electrons in their highest orbitals so they have a very little tendency to gain or lose electrons to form ions or share electrons with other elements in covalent bonds.

Sodium hydride reacts with excess water to produce aqueous sodium hydroxide and hydrogen gas:NaH (s) H2O (l) → NaOH (aq) H2 (g)A
Anuta_ua [19.1K]

NaH(s)+ H2O (l)=>NaOH(aq)+H2(g)

You want to calculate the mass of NaH, I assume.  Otherwise, the question isn't clear.  It simply says calculate the mass(??)

 

So, calculate the moles of H2 gas that satisfy the conditions of 982 ml at 28ºC and 765 torr.  But you must subtract the vapor pressure of water at 28º to get the actual pressure of the H2 gas.  So, the actual conditions are 982 ml (0.982 L) and 301 K and 765-28 = 737 torr.

PV = nRT

n = PV/RT = (737 torr)(0.982 L)/(62.4 L-torr/Kmol)(301 K)

n = 0.0385 moles H2

 

moles NaH needed = 0.0385 moles H2 x 1 mole NaH/mole H2 = 0.0385 moles NaH required

mass of NaH needed = 0.0385 moles x 24 g/mole = 0.925 g NaH

Answer:

d = 0.9 g/L

Explanation:

Given data:

Number of moles = 1 mol

Volume = 24.2 L

Temperature = 298 K

Pressure = 101.3 Kpa (101.3/101 = 1 atm)

Density of sample = ?

Solution:

PV = nRT     (1)

n = number of moles

number of moles = mass/molar mass

n = m/M

Now we will put the n= m/M in equation 1.

PV = m/M RT   (2)

d = m/v

PM = m/v RT ( by rearranging the equation 2)

PM = dRT

d = PM/RT

The molar mass of neon is = 20.1798 g/mol

d = 1 atm × 20.1798 g/mol / 0.0821 atm. L/mol.K × 273K

d = 20.1798 g/22.413 L

d = 0.9 g/L
