Explanation

Aldoses are carbohydrates that contain an aldehyde group (-CHO) in their molecular structure.

The aldehyde group is a functional group that contains a carbon-oxygen double bond and a hydrogen atom.

Examples of aldoses include glucose, galactose, and ribose.

Explanation

• The general formula for alkanes is CnH2n+2, where n is the number of carbon atoms in the molecule.
• This formula represents the saturated hydrocarbons, also known as paraffins.

Key Points:

• CnH2n is the general formula for alkenes
• CnH2n+1 is the general formula for alcohols

Explanation

When the reaction quotient (Qc) is equal to the equilibrium constant (Kc), the system is at equilibrium and is stable.

Qc = Kc indicates that the rates of forward and reverse reactions are equal, and the concentrations of reactants and products remain constant.

Explanation

CH3-CH2- is the ethyl radical.

The ethyl radical is a functional group derived from ethane (C2H6) by removing a hydrogen atom.

It leaving a highly reactive species with an unpaired electron.

Explanation

According to the Bronsted-Lowry theory, NH3 acts as a base because it can accept a proton (H^+).

According to the Lewis theory, NH3 is a base because it can donate a pair of electrons.

Explanation

CH3-CH2-CH3 is the molecular formula for propane, which is a saturated hydrocarbon (an alkane).

Explanation

Cotton is a natural fiber that contains a very high percentage of cellulose, typically around 95%.

Cellulose is a polysaccharide (a long chain of glucose molecules) that provides strength, structure, and durability to plant cell walls.

Cotton is one of the purest forms of cellulose, making it a valuable resource for textile production.

Explanation

A Lewis base is a substance that donates a pair of electrons to form a coordinate covalent bond.

This means that a Lewis base is an electron pair donor.

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

The bond formed between water molecules (H2O) is a hydrogen bond.

The bond within the water molecule itself is a covalent bond
