Enzymes are proteins that catalyse biochemical reactions. This means that they increase the speed of these reactions without being consumed themselves.
The osmosis process involves the movement of water molecules across a partially permeable membrane from a region of high water concentration to a region of low concentration.
Exercise is an important part of a healthy lifestyle. It helps to maintain a healthy weight, boosts energy levels, and reduces the risk of diseases such as heart disease.
Water and sodium hydroxide are both compounds. If you look at the Periodic table, you will see that sodium has a mass number of 23, oxygen has a mass number of 16 and hydrogen has a mass number of 1.
A reaction may happen when two or more chemicals are mixed. Sometimes you have to add heat (energy) before the reaction will occur. Not all chemicals react together when they are mixed.
You probably know by now (through your studies of chemistry) that electrons are the “magic” behind chemical reactions. They do all the hard work – moving here, moving there, joining this atom, leaving that atom, forming bonds, etc.
