Introduction: A chemical reaction is formed of reactants and products. Reactants react with each other to give one or more product. Sometimes we can visualize observations that are characteristic of the reaction. Like for example a release of a gas (bubbles are formed) or a change of color or also the formation of a precipitate. Materiel needed: Test tubes Rack of test tubes Plastic droppers Beakers Procedure: We prepare 7 beakers of 7 different solutions (that we mark from 1→ 7)

Many people think that we are now abusing modern devices to support for our own life; while others reckon that using technology brings us just good things and make our life easier. According to what I have observed and experienced‚ I believe that people‚ nowadays‚ have been overly dependent on technology. To begin with‚ it is not hard to recognize the intergral role of technology in houses. Housewives

The objective: In this experiment‚ I decided to find out how temperature would affect endothermic reactions compared to exothermic reactions. An endothermic reaction absorbs energy in the form of heat. This reaction feels cold because it is taking heat away from its surroundings. It also releases gases. An exothermic reaction is a reaction that releases energy as heat. Since the energy is released‚ the exothermic reactions feel hot. Methods/Materials I did three experiments. I mixed lemon juice
