Kimyanın Temel Kanunları: Key laws of chemistry including Kütlenin Korunumu Kanunu and Sabit Oranlar Kanunu. These fundamental principles govern chemical reactions and the composition of compounds.
• Covers conservation of mass and constant composition
• Explains how elements combine in fixed ratios to form compounds
• Provides examples and practice problems for 10. sınıf kimya students
• Includes calculations for mass ratios, empirical formulas, and percent composition

This page introduces two key laws in chemistry: the Law of Conservation of Mass and the Law of Constant Composition.
The Law of Conservation of Mass, discovered by Lavoisier, states that mass is neither created nor destroyed in chemical reactions. The total mass of reactants equals the total mass of products. An example problem demonstrates how to apply this principle to balance chemical equations.
Definition: The Law of Conservation of Mass states that the total mass before and after a chemical reaction remains constant.
The Law of Constant Composition, proposed by Proust, explains that compounds always contain the same elements in the same proportions by mass, regardless of the source or method of preparation.
Example: In water (H₂O), the mass ratio of hydrogen to oxygen is always 1:8, or 11.1% hydrogen and 88.9% oxygen by mass.
The page provides several practice problems on calculating mass ratios in compounds like Al₂S₃ and determining the amount of reactants needed to produce a given mass of product. These examples are excellent for 10. sınıf kimya çözümlü sorular practice.
Highlight: Understanding these laws is crucial for balancing chemical equations and predicting the outcomes of chemical reactions.
This page delves deeper into applications of the Sabit Oranlar Kanunu (Law of Constant Composition) with more complex examples and calculations.
The problems presented focus on determining mass ratios in various compounds, calculating empirical formulas, and finding atomic masses based on given information. These exercises are ideal for 10. sınıf kimyanın temel kanunları çözümlü sorular practice.
Example: One problem asks students to determine the mass of calcium in 22.4g of CaS, given the mass ratio of Ca to S in the compound.
The page also introduces graphical representations of mass ratios in compounds, helping students visualize the concept of constant composition. This approach aids in solving problems related to determining chemical formulas from experimental data.
Vocabulary: Empirical formula - the simplest whole number ratio of atoms in a compound.
Several problems involve calculating the percent composition of elements in compounds, which is a crucial skill for understanding chemical formulas and stoichiometry.
Highlight: The variety of problem types on this page provides comprehensive practice for 10. sınıf kimya sabit oranlar kanunu test preparation.
The final section includes problems on determining the value of subscripts in chemical formulas based on given mass ratios or percent compositions. These exercises reinforce the application of the Law of Constant Composition in real-world chemical analysis.
