| 内容摘要: |
| Quantitative chemistry is about chemical equations and what they tell you in terms of the amounts of reactants used up and products made CHEMICAL CHANGE Chemical changes have three main features: ·New substances are made ·There is an energy change between the reacting system and its surroundings ·There is fixed relationship between the masses of the reactants and products-this is called the stoichiometry of the reaction Stoichiometry is the name given to the property of pure substances to react together in whole number ratios of particles. Chemical changes are nearly always written s equations showing the reactants and products symbolically in the form of some kind of formula. CHEMICAL EQUATIONS Reactants are normally written on the left. Products are normally written on the right. The arrow→between them means reacts to give and sometimes has the conditions written above or below it. e.g. There are two different kinds of equation and although they are often used interchangeably, they really have different uses depending on which feature of the reaction is being studied: IONIC EQUATIONS These are used when we think about how one lot of substances is changed into another. They are concerned with the bonding,structure, shape, or size of the particles and the mechanism of the reaction. When writing particle equations state symbols are used,e.g. This equation tells us that a copper a quo ion reacts with two hydroxide ions to make an insoluble product. |
