Gases do not have a definite shape or volume because their molecules are widely spaced and move freely. This allows them to expand and fill any container they are in, adjusting to both shape and volume. Related Questions: Can you write the formula of the carbon dioxide gas that we exhale? Define element, compound, and … Read more
Generally, increasing temperature increases the solubility of solid solutes in liquids. For gases, higher temperatures tend to decrease solubility. This is because higher temperatures give molecules more energy to dissolve or escape from the solvent. Related Questions: Can you write the formula of the carbon dioxide gas that we exhale? Define element, compound, and mixture. … Read more
Sublimation is the transition of a substance directly from a solid to a gas without passing through the liquid phase. An example is dry ice (solid carbon dioxide), which sublimates directly into carbon dioxide gas at room temperature.

Physical properties are characteristics that can be observed or measured without changing the substance’s chemical identity, such as color, mass, and melting point. Chemical properties, on the other hand, describe how a substance reacts with other substances, forming new products, like flammability or acidity.

Atomic Number of Argon: The atomic number is defined as the number of protons in the nucleus of an atom. Since Argon has 18 protons, its atomic number is 18. Related Questions: Can you write the formula of the carbon dioxide gas that we exhale? Define element, compound, and mixture. Differentiate between a compound and … Read more
Allotropes are different structural forms of the same element, where the atoms are bonded in various ways. Carbon exhibits several allotropes, each with distinct properties. Diamond has a tetrahedral structure and is the hardest known natural material. Graphite consists of layers of carbon atoms that can slide over each other, making it soft and conductive. … Read more
Property Concentrated Solution Dilute Solution Concentration High concentration of solute Low concentration of solute Appearance Darker, more intense color Lighter, pale color Taste Stronger taste Weaker taste Example Strong saltwater, Syrup Dilute lemon juice, Tea A concentrated solution contains a large amount of solute relative to the solvent, making it more intense in flavor and … Read more
Property Compound Mixture Composition Fixed ratio of elements Variable proportions of substances Bonding Chemical bonds between elements No chemical bonding between components Separation Can only be separated chemically Can be separated physically Example Water (H₂O), Salt (NaCl) Air, Sand, Salad A compound has a fixed chemical composition with atoms bonded together, while a mixture is … Read more
An element is a pure substance made up of only one type of atom. Examples include hydrogen, oxygen, and carbon. A compound consists of two or more elements chemically bonded in fixed proportions, such as water (H₂O) or carbon dioxide (CO₂). A mixture, on the other hand, contains two or more substances physically combined, and … Read more
The formula for carbon dioxide gas, which we exhale, is CO₂. This colorless and odorless gas consists of one carbon (C) atom bonded to two oxygen (O) atoms. During respiration, our bodies metabolize glucose, and in this process, oxygen is used, and carbon dioxide is produced as a waste product. The body then expels carbon … Read more
