Chemistry Summary The particle theory: 1. Matter is made of tiny particles 2. Particles of matter are in constant motion 3. Particles of matter are held together by very strong electric forces 4. There are empty spaces between the particles of matter that are very large compared to the particles themselves. 5. Each substance has unique particles that are different from the particles of other substances 6. Temperature affects the speed of the particles. The

Experiment In this lab we were asked to observe changes and colors when mixing two or three chemicals together. The actual experiment itself used twelve different pipits and three chemicals I selected from my house. To begin‚ I first gathered everything‚ including the 96 well plate‚ 24 well plate‚ goggles‚ and gloves along with the observations of chemical changes bag. I set it up all on the the kitchen table that had paper towels on it. Next‚ I made my data table so that I could record my reactions

Data Tables: Part 1: Chemicals Well No. Observations of the Reaction A. NaHCO3 + HCl A1 Bubbles immediately formed and started popping (not rapidly). This could be seen more easily with the black paper underneath the well plate B. HCl + BTB C1 Once I added the Bromothymol Blue indicator‚ it turned an orange-like color C. NH3 + BTB E1 The reaction turned dark blue. When Bromothymol Blue reacts with an acid‚ it turned orange‚ and when it reacts with a base‚ the end result is blue. D. HCl

Chemical Reaction:- The transformation of chemical substance into another chemical substance is known as Chemical Reaction. For example: rusting of iron‚ setting of milk into curd‚ digestion of food‚ respiration‚ etc. In chemical reaction new substance is formed which is completely different in properties from the original substance‚ so in a chemical reaction chemical change takes place. Following are the signs of chemical reaction: (a) Change of state of substance. (b) Change of colour of substance

develops "PLASTICITY" which helps in manufacturing unlimited number of objects in various shapes and sizes. CERAMICS BEFORE CHRIST Ceramics is one of the most ancient industries on the planet. Once humans discovered that clay could be dug up and formed into objects by first mixing with water and then firing‚ the industry was born. As early as 24‚000 BC‚ animal and human figurines were made from clay and other materials‚ and then fired in kilns partially dug into the ground. The Greeks developed
