March 20, 2015 The five major chemical reactions are decomposition, synthesis reactions, single displacement reactions, double displacement reactions, combustion reactions. Decomposition reactions happens when a compound breaks down into smaller parts. Synthesis Reactions occurs when elements or compounds are joined together. Single Displacement Reactions happens when single elements replace an element in a compound. Double Displacement Reactions occurs when an element from each of two compounds switch places. Combustion Reactions happen when a hydrocarbon combines with oxygen. The outcome of this combustion reactions are always carbon dioxide and water.
Examples:
Decomposition
KCLO3-->KCL+O2
Single Displacement
KBr+F2-->KF+Br2
Synthesis
S8+F2-->SF6
Double Displacement
NaSO4+Pb(NO3)-->NaNo3+PbSO4
Combustion
C3H8+O2-->Co2+H2o
A mole is a unit of measurement used to express amounts of a chemical substance. It measures mass or volume of amounts of a product/reactant in a chemical reaction. Moles can be converted to grams by dividing the moles by the molar mass of the element. You can convert moles into particles by multiplying the moles by 6.022x1023. If you multiply the moles by 22.4 you …show more content…
" -Antoine-Laurent de Lavoisier (1785) Antoine Lavoisier discovered in 1785 that while a chemical reaction is taking place, matter nor mass can be gained nor destroyed. In other words, during a chemical reaction molecules have the possibility of separation, combining or coming together & multiple other possibilities but in the infinite universe, matter cannot expand nor

catalase experiement Essay

catalase: a study of enzyme action Introduction Thousands of chemical reactions take place within living cells of organisms. Many of these reactions can also be carried out in the laboratory, but outside the cell, they are often much slower. To speed up these reactions so they would take place as fast as they do in cells would require temperatures or pHs that are inconsistent with life. How then is it possible for reactions to occur in cells at rates fast enough to meet the needs of the body?…
