classify the following chemical reaction 1 through 5
9:12 Chapter 8-Chemical Reactions E... DIRECTIONS: Determine whether each statement is true or false. Write the word TRUE if the statement is true or write FALSE if the statement is FALSE. If the statement is false, change the BOLD word or words to make the statement true. 1. The substances formed as a result of a chemical reaction are called REACTANTS. 2. A CHEMICAL EQUATION uses symbols and formulas to represent a reaction. 3. A number written in front of a chemical symbol or formula is a (an) COEFFICIENT. 4. To balance the following equation, the number 2 should be placed in front of O2: KC103 ----------à KCI 02 5. In a SYNTHESIS reaction, complex substances from simpler substances. 6. The formation of carbon dioxide during combustion of fuel is an example of a DECOMPOSITION reaction. 7. In an exothermic reaction, products have MORE energy than reactants. 8. The COLLISION THEORY can be used to account for the factors that affect reaction rates. 9. CONCENTRATION, is a measure of the energy of motion of molecules. 10. Increasing surface area INCREASES reaction rate. CLASSIFY THE FOLLOWING CHEMICAL REACTIONS 1. NiC12 -------à Ni + 2. MgBr2 Cl 2 2K ------à Mg 2KB. 3. 4C 6H2 02 -----à 2C2H60 4. 2LİI Pb(NO3)2 ------à 2LINO3 + PbI2 5. 2H2O 02 ------à 2H2O2 + Name Chemical Beactions
