This chapter builds on the brief introduction to chemical reactions that was covered in Chapter 1 Atoms of Gr. The important message of this chapter is that atoms are rearranged during a chemical reaction. The atoms do not change, but how they are arranged in relation to each other does change. That means that the molecules change, even though the number of each kind of atom present at the start of the reaction, stays the same throughout. To help learners make this important conceptual connection, particle diagrams are used to represent some of the reactions in this chapter.

For example, salt dissolved in water can be recovered by allowing the water to evaporate. And, of course, that physical transformation goes through to the conversion of liquid water to its vapour state. If sand and water reacted to form different compounds it would be a chemical change. Thermal energy from the room-temperature water will continuously flow to the boiling water. A The heat added represents an energy change. Is this a physical change or chemical change?

In nature, water exists in the liquid, solid, and gaseous states. It is in dynamic equilibrium between the liquid and gas states at 0 degrees Celsius and 1 atm of pressure. At room temperature approximately 25 degrees Celsius , it is a tasteless, odorless, and colorless liquid. Many substances dissolve in water, and it is commonly referred to as the universal solvent. Similar to many other substances, water can take numerous forms. The solid phase of water is known as ice and commonly takes the structure of hard, amalgamated crystals, such as ice cubes, or of loosely accumulated granular crystals, such as snow. This lattice contains more space than when the molecules are in the liquid state.

Change is happening all around us all of the time. Just as chemists have classified elements and compounds, they have also classified types of changes. Changes are classified as either physical or chemical changes. Chemists learn a lot about the nature of matter by studying the changes that matter can undergo. Chemists make a distinction between two different types of changes that they study—physical changes and chemical changes.

Густая жидкость текла по его волосам, капала ей на лицо, попадала в рот. Она почувствовала соленый привкус и из последних сил попыталась выбраться из-под немца.

Пожалуй, дело кончится тем, что его выставят на улицу. Клушар продолжал бушевать: - И этот полицейский из вашего города тоже хорош. Заставил меня сесть на мотоцикл. Смотрите сюда! - Он попытался поднять левую руку.
