Explain the term "hydrated salt." A hydrated salt contains water molecules within its crystal structure.

Why are catalysts important? Catalysts increase the rate of chemical reactions without being consumed in the process.

What is the primary source of sulfur dioxide in the air? Burning fossil fuels is the primary source of sulfur dioxide.

Why is sodium chloride soluble in water? Sodium chloride dissolves in water due to attraction between sodium ions and water molecules.

How can acidic soil be neutralized? Acidic soil can be neutralized by adding lime (calcium oxide or calcium carbonate).

What happens when carbon dioxide is passed through lime water? Lime water turns milky when carbon dioxide is passed through it, due to formation of calcium carbonate.

Name a metal that can be cut with a knife. Sodium is a soft metal that can be cut easily with a knife.

What is the effect of adding salt to ice? Adding salt lowers the freezing point, causing ice to melt faster.

Give one example of an amphoteric oxide. Aluminum oxide is an amphoteric oxide, as it reacts with both acids and bases.

Why do we store acids in glass containers? Acids are stored in glass containers because they do not react with glass.

What is a displacement reaction? A displacement reaction occurs when a more reactive metal displaces a less reactive metal from its compound.

What is the common name of calcium oxide? The common name of calcium oxide is quicklime.

Describe the flame color observed when sodium salts are heated. Sodium salts give a characteristic bright yellow flame.

Why is plastic considered a non-biodegradable material? Plastic does not break down naturally by microbes, making it non-biodegradable.

Explain how ozone protects life on Earth. Ozone absorbs harmful ultraviolet radiation from sunlight, protecting life on Earth.
