A student creates a “volcano” by mixing vinegar and baking soda is a Experiment in the following way.
Explanation:
- The baking soda and vinegar volcano is a fun chemistry project that a student can do to simulate a real volcanic eruption or as an example of an acid-base reaction.
- The chemical reaction between baking soda (sodium bicarbonate) and vinegar (acetic acid) produces carbon dioxide gas, which forms bubbles in dishwashing detergent. The chemicals are non-toxic (though not tasty), making this project a good choice for scientists of all ages.
-
The cool red lava is the result of a chemical reaction between the baking soda and vinegar.
- In this reaction, carbon dioxide gas is produced, which is also present in real volcanoes.
- As the carbon dioxide gas is produced, pressure builds up inside the plastic bottle, until—thanks to the detergent—the gas bubbles out of the mouth of the volcano.
The answer is C. Ionic and covalent bonding exists in the same compound and intermolecular forces exist between different compounds. And that is way called intermolecular forces.

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.
