Chemistry : The Six Types Of Chemical Reaction In Chemistry

What is the appearance of reactant, Evidence of chemical reaction, and properties of a product?

A chemical reaction is when substances (reactants) change into other substances (products). The five general types of chemical reactions are synthesis (also known as direct combination), decomposition, single replacement (also known as single displacement), double replacement (also known as double displacement), and combustion. In this lab, the five general types of chemical reactions were conducted and observations were taken before, during, and after the reaction. Then the reactants and observations were used to determine the products to form a balanced chemical equation. The purpose of this lab was to learn and answer the question: How can observations be used to determine the identity of substances produced in a chemical reaction?

One type of chemical reaction, called combustion, involves the burning of various compounds and elements. Some substances are more

When the two smaller reactants join together, water is produced and removed during the synthesis of the larger molecule. This is also called Dehydration Synthesis.

There are now many classification systems to classify the different types of reactions. These include decomposition, polymerization, chain reactions, substitute reactions, elimination reactions, addition reactions, ionic reactions, and oxidation-reduction reactions.

The difference between endothermic and exothermic reactions is that endothermic reactions absorb heat, and exothermic give off heat. Dilution of ammonium chloride is an example of an endothermic reaction. This is the active ingredient in chemical ice packs you can obtain in a pharmacy. Other reactions are melting and boiling which also absorb heat to happen, although you may not consider them chemical reactions. Combustion is a typical exothermic reaction any type of burning.An exothermic reaction occurs if the energy of the bonds formed in the products

Chemical change results in one or more substances of entirely different composition. Chemical change requires a chemical reaction.

There are five clues that help indicate if a chemical change occurs. The clues to a chemical change include a change of colour, the forming of a precipitate, the forming of gas bubbles, the production of heat or light, and if the change is difficult to reverse. In the chemical reactions lab, several chemical changes will occur. Participants must use this knowledge to decipher what change has occurred after the chemical

The purpose of this lab is to become more familiar with the products of different types of chemical reactions by conducting several chemical reactions and observing the changes that occurred. In addition, by performing various experiments, the observations will help in writing chemical equations, which represent the process involved in a chemical reaction. Overall, the chemical changes observed throughout can determine the products that are formed from the reactants. In chemical reactions, substances that are referred to as reactants produce other substances called products. There are several ways to determine that a chemical reaction has occurred, and which type of reaction has taken place, exothermic or endothermic, which will help predict

Exothermic reactions can be used for everyday purposes. For example, hand warmers and self-heating cans for drinks (such as coffee) use exothermic reactions.

The four kinds of chemical reactions are synthesis, decomposition, single-displacement and double-displacement. Materials: Bunsen burner, sparker, tongs, 5 test tubes, scoop, wooden splint, lead(II)nitrate, magnesium wire, copper(II) carbonate, hydrochloric acid, zinc, potassium iodide, test tube tack, googles, apron, gloves and a metal test tube holder. Methods: Experiment 1: Synthesis 1, Obtain a piece of magnesium wire.

Introduction During this unit, we learned about 5 types of chemical reactions. They consist of Synthesis, Decomposition, Single Displacement, Double Displacement, and Combustion. A synthesis reaction or direct combination reaction is one of the most common types of chemical reactions. In a synthesis reaction, two or more chemical species combine to form a more complex product. A + B → AB.

Chemical reactions that release energy are called exothermic reactions, these reactions are observed by an increase in temperature of the reaction mixture.

In the chemical and physical change lab, we figured out what a chemical change is. A chemical change is a change in which one or more substances are converted into a different substances. That means if a chemical change occurred the substances will be turned into a different substance. In order to know if a chemical change happened you will see bubbles, a color change, energy released as heat and light or a solid participate. The first example, of a chemical change in this lab is bubbles. In stations 6 and 8 each had bubbles in them. In station 6 the zinc was put into the HCI acid and once they touched they got bubbly and cloudy. Also in station 8 when a spoonful of baking soda and HCI acid touches the solution, it started to bubble and fizz.

When we did the labs I notice many evidece that there are during a chemical reactions since we did many labs to be able to understand this conecpts. Another thing is to be able to notice there are chemical reaction is when it gives off or takes energy an example of this is when we did the chalk with vinger you either got a big reaction or you just get a small bubbling. One of the other thing is when gas is formed or the smell of the reaction, change in colors and change of presipitates. Antoher big thing in a chamical reaction is oxidations. When we did the labs I notice many of these things.
