     Stoichiometry is the basic chemical calculation that states quantitative relation of chemical formulas and chemical equations. Here are the materials you need to know to understand, from the concept of moles and molar masses, empirical formulas and molecular formulas, basic stoichiometry of solutions and ideal gases, and the writing and equalization of reactions, with examples of problems and discussions. I. BASIC LAW OF CHEMICAL SCIENCE A. The Law of Conservation of Mass (Lavoisier's Law)       "The mass of substances before and after the reaction is the same". Example: S + O 2 → SO 2 2 gr 32 gr 64 gr B. Fixed Comparative Law (Proust Law) "The ratio of the elemental masses in each compound is fixed" Example: H 2 O → mass H: mass O = 2: 16 = 1: 8 C. The Law of Multiple Comparisons (Dalton's Law)       "If two elements can form two or more compounds, and the mass of one element is equal, the ratio of th...

Chemical reactions can happen around us, not just in the laboratory. Material to build new products. Every time we cook or are clean, it is also an ingredient in action. Our bodies live and grow thanks to chemical reactions. There are reactions when we take medicine, spasms, and breathing. Here are 10 examples of chemical reactions in everyday life. This looks a small example, because we see and experience hundreds of thousands or even more chemical reactions every day. 1. Photosynthesis Photosynthesis is a process used by plants and other organisms to convert light energy, usually from the Sun, into a chemical energy that can be liberated to fuel organism activity. This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water. In most cases, oxygen is also produced as a waste product. Most plants, mostly algae, and cyanobacteria do photosynthesis, and these organisms are called photoautotrophs. Photosynthesis main...

Teacher            : Good morning students. Students           : Good morning miss. Teacher            : How are you today? Students           : I am fine, miss. How about you? Teacher            : I am great.  Teacher       : Hi Sarah, are you feeling better             now? You were sick yesterday, right? Sarah             : I am getting much better                       miss. Teacher     : Good. Okay, we will start our lesson. Sunday yesterday we've been     talking      about atoms. Now we will discuss about Classes and periods in the periodic elements periodic system. Before we start,...

How do oil spills occur? Oil Spills may happen for several reasons. 1. When oil tankers have equipment faults . When oil tankers break down, it may get stuck on shallow land. When the tanker is attempted to move out of shallow land, abrasion may cause a hole in the tanker that will lead to large amounts of oil being released into the oceanic bodies. However, although this form of oil spill is the most commonly known and has the highest media attention, only 2% of oil in water bodies is a result of this action. 2. From nature and human activities on land. The large majority of oil spilled is from natural seeps geological seeps from the ocean floor as well as leaks that occur when products using petroleum or various forms of oil are used on land, and the oil is washed off into water bodies. 3. Water Sports. Other causes of oil spills are spills by petroleum users of released oil. This happens when various water sports or water vehicles such as motorboats and jet ...

Electrolysis is dissociating an electrolyte into an ion on the electrode in the presence of an electric current. Electrical conduction through an electrolyte solution will result in a chemical change. Matter is everything that occupies space and has mass. As the universe is composed of matter, tables, chairs and air we normally breathe is one included into the material. Element is a substance that can not be changed into a simpler form under normal or normal laboratory conditions. In other words, the element is a pure substance that can not be deciphered into a simple substance through a chemical reaction. The compound is a single substance consisting of two or more elements which can be broken down into simpler forms through chemical reactions. Benzene, also known as the chemical formula C6H6, PhH, and benzol, is an organic chemical compound that is colorless and flammable liquid and has a sweet smell. Bases are the opposite of acids, ie they are intended for elements / chemic...

Definitions: Compare and contrast essays  are multi-paragraph compositions that explain ways in which two (or, very occasionally, more) subjects are similar or different. In these papers,  compare  means describing similarities between the subjects. When we are comparing Uberman and Catman, we might describe their tragic backstories, their secret double lives, and their fondness for crime fighting. Basically, the comparison tells what they have in common. The arch-enemy of comparing is contrasting. When you  contrast  two things, you explain ways in which they are different. Contrasting Catman and Uberman, we might take note of the way Catman uses his opponent's strength against him, while Uberman depends on brute force. HOW TO WRITE A COMPARE AND CONTRAST ESSAY The purpose of a compare and contrast essay is to analyze the differences and/or the similarities of two distinct subjects. A good compare/contrast essay doesn’t only point out how the su...
