Answer:

Explanation:

(A) Phenol gives violet color by complexation with Fe3+ solution . It is best identification...

(B) For b , same phenolic test can be done ...But other esterification is also possibility...

(C) Picric acid has a particular identification test ,  

(D) Here , like the first one , phenolic test with FeCl3 gives violet color for 4-ethylphenol and no color for ethyl phenyl ether...

Solve the below problem.
blagie [28]

the balanced equation for the formation of ammonia is as follows

N₂ + 3H₂ --> 2NH₃

stoichiometry of H₂ to NH₃ is 3:2

in gases number of moles of gas is directly proportional to volume of gases.

therefore molar ratio is equal to volume ratios.

this means volume ratio of H₂ to NH₃ is 3:2

volume of H₂ reacted - 54.1 L

if 3 L of H₂ forms - 2 L of NH₃

then 54.1 L of H₂ forms - 2/3 x 54.1 = 36.1 L of NH₃

volume of NH₃ formed is 36.1 L

A compound's molecular formula must always be different than the compound's empirical formula. TRUE FALSE
Juli2301 [7.4K]

Answer: False

Explanation:

Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.  

Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.

Example: CH_4 has similar molecular formula and empirical formula as the elements are already present in simplest of the ratios.

C_2H_2 has molecular formula of C_2H_2 but CH as the empirical formula.

The reactants in a chemical reaction contain 900 J of chemical energy. The products of the reaction contain 9000 J of chemical e
natta225 [31]
For the reaction to take place the energy of the reactants must reach to the energy level of the products:
we have 900 J in the reactants and 9000 J for the products so the reactants need 8100 J to reach to the value of energy of products (900 + 8100 = 9000)
So the correct answer is C. <span>The reaction absorbs 8100 J of energy from the surroundings as it proceeds. </span>
