Explanation

 Propanone is the chemical name for acetone, which is the primary solvent used in most nail polish removers. 

Explanation

A fatty acid is a carboxylic acid with a long aliphatic chain.

Phthalic acid has a benzene ring structure, which is not characteristic of fatty acids

Explanation

The total energy of a hydrogen atom in its ground state is negative. 

The energy of a hydrogen atom in its ground state is typically represented as -13.6 eV.

A negative energy value indicates that the electron is bound to the nucleus and requires energy to be overcome to escape.

The ground state is the lowest energy level an electron can occupy in a hydrogen atom. 

Explanation

Iso-octane (2,2,4-trimethylpentane) is assigned an octane number of 100 because it resists knocking in engines.

It serves as the standard reference fuel for high-quality performance in internal combustion engines.

Explanation

Glycine is the simplest and neutral amino acid, with no extra acidic or basic side chains.

It has a hydrogen atom as its side group (R group), making it electrically neutral at physiological pH.

Explanation

Aeroplanes fly in the troposphere, which is the lowest layer of the Earth's atmosphere, extending up to about 12 km (7.5 miles) above the Earth's surface.

The troposphere is where weather occurs, and it's the layer where aircraft operate, typically cruising at altitudes between 30,000 to 40,000 feet (9,100 to 12,200 meters).

Explanation

Chlorine (Cl2) is a strong oxidizing agent, which means it can accept electrons from other substances and cause them to be oxidized.

Chlorine is a powerful oxidizer and is often used as a disinfectant or bleach.

Explanation

• Solubility is typically expressed in grams of solute per 100 grams of solvent, denoted as g/100g or g/100mL.
• This unit is called the percentage concentration or percentage composition.

Explanation

The Fischer-Tropsch synthesis involves the combination of CO and H₂ to form alkanes. 

CO (carbon monoxide) and H₂ (hydrogen): are collectively known as "syngas".

The Fischer-Tropsch process uses a catalyst to convert this syngas into liquid hydrocarbons, primarily alkanes. 

Explanation

 The precise definition of organic chemistry is the Study of carbon-containing compounds. 

Organic chemistry focuses on the study of compounds that contain carbon, regardless of whether they are hydrocarbons or their derivatives.

While hydrocarbons are a subset of organic compounds, the definition encompasses all carbon-based molecules
