- 3. RECAP
- 4. Presented by Kay Estelle F. Gepulango CLASS LARANA COMPANY CHEMISTRY FEBRUARY 2024
- 5. Fill in the missing letter
- 17. 2 Evaluate the difference between direct combination, decomposition, single- replacement, double-replacement & combustion. Objectives 1 Understand the chemical equations 3 Demonstrate the step-by-step process of balancing chemical equations.
- 19. Chemical equations are symbolic representations of chemical reactions in which the reactants and the products are expressed in terms of their respective chemical formulae. What is Chemical Equation?
- 20. Balanced Chemical Equation an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge are the same for both the reactants and the products.
- 21. Product The substances produced at the end of the reaction are known as the products Reactant The substances that go into a chemical reaction are called the reactants
- 22. example
- 23. Why do we need to balance chemical eaquation? Balancing a chemical equation is important in order to follow the law of conservation of mass. The law of conservation of mass overlooks the balancing of a chemical equation.
- 24. example
- 25. example
- 28. A reaction in which two or more reactants combine to form a single product is known as a combination reaction. Direct Combination Reaction
- 29. Direct Combination Reaction A + B → AB
- 30. example
- 31. A reaction in which a single compound breaks into two or more simpler compounds is known as a decomposition reaction. Decomposition Reaction
- 32. Decomposition Reaction AB → A + B
- 33. example
- 34. A chemical reaction in which a more reactive element displaces a less reactive element from its aqueous salt solution. Single-Replacement Reaction
- 35. Single-Replacement Reaction A + BC → AC + B
- 36. example
- 38. A chemical reaction in which ions get exchanged between two reactants which form a new compound is called a double displacement reaction. Double- Replacement Reaction
- 39. Double-Replacement Reaction AB + CD → AD + CB
- 40. example
- 41. A chemical reaction that involves the formation of an insoluble product (precipitate; solid) is called Precipitation reaction. The reactants are soluble, but the product formed would be insoluble and separates out as a solid. Combustion Reaction
