1. chemical equation
1.1. balancing equations :
1.1.1. what is it?
1.1.1.1. Balancing equations ensures that the number of atoms for each element is equal on both sides of a chemical equation, upholding the law of conservation of mass, which states that matter is neither created nor destroyed in a chemical reaction.
1.2. chemist :
1.2.1. Jean Beguin in the year 1615.
1.3. classification of reactions:
1.3.1. what's is it?
1.3.1.1. Classification of chemical reactions categorizes them based on how reactants transform into products. This helps in predicting reaction outcomes and understanding the processes involved.
1.3.2. types of chemical reactions:
1.3.2.1. 1. Synthesis (Combination) Reactions
1.3.2.2. 2. Decomposition Reactions
1.3.2.3. 3. Single Displacement (Replacement) Reactions
1.4. Energy changes:
1.4.1. endothermic
1.4.2. exothermic
2. chemical bond :
2.1. what is it?
2.1.1. is the association of atoms or ions to form molecules and other structures.
2.2. types:
2.2.1. ionic bonds:
2.2.1.1. oppositely charged ions, formed by the transfer of electrons from one atom to the other
2.2.2. Covalent bonds:
2.2.2.1. sharing of electrons pairs between atoms
2.2.3. Metallic bonds:
2.2.3.1. are shared electrons among metal atoms.
3. Solubility:
3.1. what is it ?
3.1.1. the ability of a substance (solute) to dissolve in a (solvent)
3.2. The factor effect solubility:
3.2.1. temperature,pressure and nature of the solute and solvent
3.3. Dissolution rate:
3.3.1. particle size,stirring and temperature can effect how quickly a solute dissolves
4. Reaction rate:
4.1. what is it:
4.1.1. is the speed a which a chemical reaction proceeds.
4.2. factors that affect the reaction rate
4.2.1. temperature
4.2.2. concentration
4.2.3. surface area
4.2.4. presence of catalysts
4.3. measured:
4.3.1. observing changes in concentration,color or volume of gas produced can be measured
