Characteristics of Mixtures

A mixture consists of two or more substances that are physically combined but retain their individual properties.
Components of mixtures can be separated through physical means such as filtration or distillation.

Tap Water Components

Common substances in tap water include minerals, chlorine, and fluoride.
Some substances, like heavy metals or specific pollutants, may not be mentioned as components.

Main Component of Air

The primary component of air is nitrogen, making up about 78% of the atmosphere.
Oxygen accounts for approximately 21%, with trace amounts of other gases.

Milk Composition

Milk is primarily composed of water, fat, lactose, proteins, and various vitamins and minerals.
Some substances, such as artificial sweeteners or colorants, may not be key components.

Crude Oil Composition

Crude oil is mainly comprised of hydrocarbons, which are combinations of hydrogen and carbon atoms.
It also contains various organic compounds and may include sulfur and nitrogen.

Ink Composition

Ink is primarily made of pigments or dyes, solvents (like water or oil), and additives for properties like flow and drying.

Gunpowder Components

Gunpowder consists mainly of potassium nitrate (saltpeter), charcoal, and sulfur.
These components work together to create explosive reactions.

Purpose of Mixing Salt in Water

Salt is mixed in water to create solutions that enhance flavor in cooking.
Saltwater is also used for preservation and other applications.

Main Component of Tomato Soup

The main ingredient in tomato soup is tomatoes, usually combined with water, cream, spices, and other flavorings for taste.

Soap Components

Soap is made from fats or oils, combined with an alkali (like sodium hydroxide).
It may contain fragrances, colorants, and other ingredients for specific functions.
