Explanation

Glucose (C6H12O6) is a type of carbohydrate, specifically a simple sugar or monosaccharide.

It is a vital source of energy for many living organisms, including humans.

Glucose is a primary component of many carbohydrates, such as starch, cellulose, and glycogen.

Explanation

Lactose, also known as milk sugar.

It is a disaccharide composed of galactose and glucose molecules.

It is found in milk and other dairy products.

Explanation

The functional group -COOH is the carboxyl group, which is a characteristic functional group of carboxylic acids.

Carboxylic acids are a class of organic compounds that contain this group, examples include:

• Formic acid (HCOOH)
• Acetic acid (CH3COOH)
• Citric acid (C6H8O7)

Explanation

• Organic chemistry is the branch of chemistry that deals with hydrocarbons and their derivatives.
• They are compounds containing carbon and hydrogen atoms.
• It may also contain other elements like oxygen, nitrogen, and sulfur.

Explanation

The stratosphere is the second layer of Earth's atmosphere as you go upwards, lying above the troposphere and below the mesosphere.

The layers of the Earth's atmosphere, in order from the surface, are:

1. Troposphere (up to about 12 km/7.5 miles)
2. Stratosphere (up to about 50 km/31 miles)
3. Mesosphere (up to about 85 km/53 miles)
4. Thermosphere (up to about 600 km/373 miles)

Explanation

• The nucleus of an atom contains protons and neutrons.
• The nucleus is the central part of an atom.
• Protons have a positive charge.
• Neutrons have no electric charge.
• Electrons are found outside the nucleus
• The nucleus makes up much less than. 01% of the volume of the atom,
• But typically contains more than 99.9% of the mass of the atom.

Explanation

• A Neutralization reaction is a specific type of reaction where an acid and a base react to form a salt and water only, with no other products.
• This reaction is characterized by the elimination of acidic and basic properties, resulting in a neutral solution.
• Example: HCl (acid) + NaOH (base) → NaCl (salt) + H2O (water)

Explanation

Global warming is primarily caused by the increasing levels of carbon dioxide (CO2) in the Earth's atmosphere, which traps heat and leads to a warming effect.

The main reason for this increase is human activities such as:

• Burning fossil fuels like coal, oil, and gas
• Deforestation and land-use changes

Explanation

The equilibrium constant, Kc, for the reaction:

N2 + O2 ⇌ 2NO is unitless (No unit).

Since the number of moles of gas is the same on both the reactant and product sides (2 moles).

The concentration terms in the equilibrium constant expression cancel out, leaving Kc without units.

Explanation

Ozone (O3) is a gas found in the stratosphere.

A stratosphere layer of the atmosphere that extends from about 12 to 50 kilometers (7.5 to 31 miles) above the Earth's surface.

The ozone layer, also known as the ozonosphere.
