What are 3 different kinds of chemical reactions?
There are actually four different kinds of chemical reactions. (For our purposes, the "=" sign will symbolize the yield sign)
- synthesis reaction: when two or more substances combine
ex: A + B = AB
- decomposition reaction: this is the breakup of a substance
ex: AB = A + B
- single replacement reaction: this is when a single element with replace an element of a substance
ex: A + BC = AB + C
- double replacement: two compounds switch "partners" with the other compounds to form new substances
ex: AB + CD = AD + CB
1. All matters is composed of indivisible atoms. 2. All atoms of a given element are identical in mass and all other properties. 3. Different elements have different atoms. 4. Atoms are indestructible and retain their identities in chemical reactions. 5. Chemical reactions involved the combination, separation, and rearrangement of atoms.
No, it is not a chemical reaction. Chemical reactions occur when one or more chemical compound reacts to give one or more different chemical compounds. When oil and water are mixed, they can be separated to give the original amounts of oil and water without any new chemical compounds <==============================================3
There are four types of chemical reactions: 1. Synthesis / Direct Combination: These chemical reactions occur where two or more substances react together to form just one product. 2. Decomposition: Decomposition reactions have just one reactant which breaks up to from two or more simpler products. 3. Single Displacement: Such types of chemical reactions occur when a more reactive element displaces a less reactive on from a solution its compounds. 4. Double Displacement: Double displacement…
John Dalton's five postulates of Atomic Theory: 1) All matter is composed of indivisible atoms 2) All atoms of a given element are identical in mass and all other properties 3) Different elements have different atoms; for example, some atoms have different masses 4) Atoms are indestructible and retain their identities in chemical reactions 5) Chemical reactions involve the combination, separation, and rearrangement of atoms
For salts: 1. After the color and odor. 2. After the products of some chemical reactions. 3. After a crystallographic study. 4. After a chemical analysis. 5. After a thermogravimetric study. For bases: 1. After the color and odor. 2. After the products of some chemical reactions. 3. After the determination of pH. 4. After a chemical analysis. 5. After a thermogravimetric study.
There are four common types of chemical reactions. 1. Synthesis Reactions A+B->AB This kind of reactions build or synthesize things. An example would be building protons from amino acids. 2. Decomposition Reactions AB->A+B These are mostly catabolic reactions. An example would be digesting food. 3. Exchange Reactions AB + CD -> AD + CB These exchange parts and make a new chemical compound. 4. Reversible Reaction A+B <-> AB Chemical compounds can be both made…
NOT USEFUL AT ALL: 1) All matter is made of atoms. Atoms are indivisible and indestructible. 2) All atoms of a given element are identical in mass and properties 3) Compounds are formed by a combination of two or more different kinds of atoms. 4) A chemical reaction is a rearrangement of atoms. Modern atomic theory is, of course, a little more involved than Dalton's theory but the essence of Dalton's theory remains valid. Today…
How does water reduce the activation of energy for reactions How does matter make chemical reactions possible Why don't solids react outside of aqueous solution?
1. Each element is composed of tiny particles called atoms. 2. All atoms of a given element are identical; atoms of different elements are different and have different properties (e.g. masses). 3. Atoms of an element are not changed into different types of atoms by chemical reactions; atoms are neither created not destroyed in chemical reactions. 4. Compounds are formed when atoms of more than one element combine; a given compound always has the same…
