Define viscosity.

Back

Viscosity is the property of a liquid that measures its resistance to flow or deformation. High viscosity liquids, like honey, flow slowly, while low viscosity liquids, like water, flow easily.

What is a chemical change?

Back

A chemical change is a process where substances transform into different substances with new chemical properties. Examples include combustion, rusting, and digestion.

What happens when baking soda and vinegar are mixed?

Back

When baking soda (sodium bicarbonate) and vinegar (acetic acid) are mixed, they react to produce carbon dioxide gas, water, and sodium acetate. This reaction creates bubbles.

What is the difference between a physical change and a chemical change?

Back

A physical change alters the form or appearance of a substance without changing its chemical composition (e.g., melting ice). A chemical change results in the formation of new substances (e.g., burning wood).

What is the significance of chemical reactions in everyday life?

Back

Chemical reactions are fundamental to processes such as cooking, cleaning, and metabolism. They involve the transformation of substances and are essential for life.

Front

What is the role of catalysts in chemical reactions?

Back

Catalysts are substances that speed up chemical reactions without being consumed in the process. They lower the activation energy required for the reaction.

Front

What is the pH scale?

Back

The pH scale measures the acidity or alkalinity of a solution, ranging from 0 (very acidic) to 14 (very basic), with 7 being neutral.

Front

What is an alkene?

Back

Alkenes are hydrocarbons that contain at least one carbon-carbon double bond. They are unsaturated and can undergo addition reactions.
