World Youth Chemistry Knowledge Competition
The online exam for the World Youth Chemistry Knowledge Competition consists of three main sections: basic chemistry knowledge, such as the periodic table of elements, types of chemical bonds, and the states and properties of matter; chemical phenomena and scientific principles, including factors affecting the rate of chemical reactions, acid-base neutralization theory, and the impact of human activities on the chemical environment; and practical applications of chemistry, including the use of common chemical instruments, analysis of simulated chemical experiments, and basic applications of chemistry in daily life (such as the principles behind food additives).
The exam questions are diverse in type, and the difficulty level is adjusted based on age and knowledge level. The children's group focuses on mastering foundational knowledge, while the youth group emphasizes the application of principles and problem-solving skills.

Entry Requirements：
1、Basic Knowledge of Chemistry
Focus on fundamental chemical concepts, including the structure and application of the periodic table, the formation and types of chemical bonds, and the composition and classification of substances. It systematically examines the properties of chemical substances, basic types of chemical reactions, and knowledge related to stoichiometry. It also covers the characteristics of different elements and their existence forms in nature, as well as an in-depth understanding of the structure of chemical substances, the laws of chemical changes, and chemical diversity—including the states of substances, energy changes in chemical reactions, and an overview of major chemical systems.
2、Chemical Phenomena and Scientific Principles
Explore the causes, mechanisms, and impacts of chemical events, such as the conditions for chemical reactions to occur, the shift of chemical equilibrium, and redox phenomena of substances. It analyzes the regulatory principles of chemical reaction rates and the theory of acid-base ionization. It also conducts in-depth research on basic theories like the relationship between molecular structure and properties, fundamentals of chemical thermodynamics and kinetics, and ion equilibrium in solutions. Additionally, it explores the impact of human activities on the chemical environment (e.g., the formation of acid rain, emissions of greenhouse gases).
3、Chemical Practice and Application
Strengthen laboratory skills, including the use of common chemical instruments (such as beakers, test tubes, alcohol lamps, and burettes) and basic operations of chemical experiments. Through case studies simulating real scenarios, it analyzes chemical experimental data and phenomena, and designs simple chemical experimental schemes. It initially applies chemical calculation tools to balance chemical equations, calculate reaction quantities, and convert solution concentrations.
4、Question Types and Difficulty Levels
The question types are diverse, including multiple-choice questions, fill-in-the-blank questions, short-answer questions, essay questions, and experimental design questions. Based on age and knowledge level.
