Answer: Option (C) is the correct answer.
Explanation:
As the given reaction is as follows.

According to Le Chatelier's principle, any disturbance caused in an equilibrium reaction will shift the equilibrium in a direction that will oppose the change.
Hence, in order to favor the formation of products when we remove
then there will occur decrease in it's concentration.
As
is forming on the product side and equilibrium will shift in the direction where there is less stress.
Hence, then equilibrium will shift in the forward direction, that is, on the products side.
Thus, we can conclude that removing
as it is formed would force the reaction to favor the products.
Using the rule Q=mcdeltaT
Q=0.3850j/g*22.8*875
Q=7505.19 J
The melting point of any substance is its physical property.
colour of any substance is also its physical property.
However TNT is a chemical property. It is explosive as it dissociates into nitrogen gas , water, Carbon monoxide and carbon.
the reaction can be given as
2 C7H5N3O6 ---> 3 N2 + 5 H2O + 7 CO + 7 C
Due to carbon it gives as sooty flames
First, divide the given mass of lead (ii) chloride by the molar mass of the compound. The molar mass is equal to 278.1 g/mol.
n = m/M
where n is the number of moles, m is the given mass, and M is the molar mass. Substituting the known values,
n = 473.7 g / 278.1 g/mol
n = 1.7 mols
Then, it is to be remember that as per Avogadro, every mol of a substance contains 6.022 x 10^23 formula units.
N = (1.7 mols)(6.022 x 10^23 formula units/mol)
N = 1.02 x 10^24 formula units
Answer: 1.02 x 10^24 formula units
