Answer:
IR provides structural information about a molecule. TLC and melting point analysis do not provide structural information.
Explanation:
IR gives information about the functional groups present in a molecule. The vibrational frequency of each functional group gives information about the structure of the entire molecule.
Structural features of a molecule are deduced by matching the vibrational frequencies of groups obtained from the IR spectroscopy with that of known functional groups in literature.
Melting point is a qualitative method that can only yield information about the identity of a compound and not its structure. Each compound has its unique melting point recorded in literature and any pure sample of the same compound must have the same sharp meting point.
Thin-layer chromatography (TLC) is a chromatography technique used to separate non-volatile mixtures. After separating the components of the mixture, it does not give any information regarding the identity or the structure of the components of the mixture.
Therefore, only IR yields structural information about a sample.
Answer:then he has a lot of gas

Physical change since it's getting physically hammered into a sheet
Answer:
The percent yield is 42.52%.
Explanation:
Theoretical yield of beryllium chloride = 12.7 g
Actual yield of the beryllium chloride = 5.4 g
The formula used for the percent yield will be :
Now put all the given values in this formula, we get:
The percent yield is 42.52%.
<h2>Hey there!</h2>
<h3>Basic solution contain no OH - ions, is the correct option.</h3>
<h2>Explanation:</h2>
<h3>The solution which produce H+ ions is known as Acidic solution. </h3>
<h3>The solution which produce OH- ions is known as Basic solution. </h3>
<h3>So,here option number "C" is correct statement, rest all options are incorrect. </h3>
