Explanation

The relative atomic mass of a neutron is approximately 1.0087 amu (atomic mass units), slightly more than that of a proton (about 1.0073 amu)

Explanation

The atomic mass of carbon is defined as 12.01 amu (atomic mass unit).

Since carbon exists as a single element, its molecular mass is also 12.01 amu. 

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

Explanation

In methane (CH₄), the carbon atom forms four sigma bonds with hydrogen atoms.

To form these four equivalent bonds, carbon undergoes sp³ hybridization, resulting in a tetrahedral structure.

Explanation

Chlorofluorocarbons (CFCs) release chlorine atoms in the stratosphere, which break down ozone (O₃) molecules.

This reaction is the main cause of ozone layer depletion.

Explanation

 Knocking causes incomplete combustion and inefficient engine performance, which reduces the efficiency of an engine.

Explanation

 When capacitors are connected in parallel, their capacitances add up directly:

C_eq = C₁ + C₂ + C₃ = 2 + 2 + 2 = 6 µF

Explanation

• Sugar (a solid) dissolves in water (a liquid) to form a solution, making it a classic example of a solid-liquid solution.
• The sugar molecules (solute) are dissolved in the water molecules (solvent), resulting in a homogeneous mixture.

Explanation

In qualitative analysis, a sample can be a solid, liquid, gas, or a mixture.

A mixture is a physical combination of two or more substances, where each substance retains its chemical properties.
