If a substance reacts with oxygen, the chemical reaction is most likely a combustion reaction.
Decomposition Reaction Series To DetermineChemists use activity series to determine whether which type of reaction will occur single replacement Which statement is usually true about the relationship between activation energy and reaction rates High activation energy barriers result in low rates.The equation below shows a reaction that produces calcium carbonate.![]() Ca(OH)2(s) CO2(g) mc032-1.jpg CaCO3(s) H2O(l) Which describes a way to speed up the collisions between calcium hydroxide and carbon dioxide molecules to produce calcium carbonate faster Reduce the volume of the container. Which is true about reaction rates Reaction rates are not related to spontaneity. What is this type of chemical reaction called combustion A double replacement reaction can be best described as a reaction in which ions are exchanged between two compounds. Sodium chloride reacts with copper sulfate to produce sodium sulfate and copper chloride. NaCl(aq)CuSO4(aq)---Na2SO4(aq)Cu2(s) This equation represents a double replacement reaction. Which type of chemical reaction occurs in C6H12 9O2--- 6CO2 6H2O combustion Which is a characteristic of a decomposition reaction Substance XYZ breaks down into X, Y, and Z A chemical reaction has two elements as reactants. Which type of reaction might occur synthesis A chemical reaction in which one element replaces another element in a compound can be categorized as a single displacement reaction. In which type of chemical reaction do two or more substances combine to form one substance synthesis Which type of chemical reaction occurs in 2KClO3---2KCl 3O2 decomposition Propane burns in air to produce carbon dioxide and water. Which products would form if chlorine gas was bubbled through a solution of sodium bromide NaCl and Br2 The production of water proceeds according to the following equation. H2(g) O2(g)---2H2O(g) Which describes a way to speed up the collisions between hydrogen and oxygen molecules to produce more water Place the reactants in a smaller container. Which topic is commonly used to explain activation energy and how chemical reactions happen collision theory Consider the reaction below. C2H4(g) H2(g)---C2H6(g) Which change would likely cause the greatest increase in the rate of the reaction increase temperature and increase pressure Ben observes how quickly some dry wood is burning in a campfire. Which term best relates to Bens observation reaction rate An increase in temperature affects the reaction rate by increasing the number of molecules that have sufficient kinetic energy to react. Which applies to the collision theory Particles need to collide in order to react. A change in which factor will affect the rate of reaction only when gases are involved pressure Which best explains why sawdust burns more quickly than a block of wood of equal mass under the same conditions More molecules in the sawdust can collide with oxygen molecules. Mg(s) 2HCl(aq)---H2(g) MgCl2(aq) What is the most likely effect of an increase in pressure on this reaction The reaction rate decreases. Which will cause an increase in the reaction rate between molecules Molecules collide more frequently. The liquid vigorously bubbles as the solid dissolves into the solution. What will most likely happen if the temperature of the liquid is slightly reduced Fewer bubbles will be produced because of fewer collisions of reactant molecules. An increase in temperature affects the reaction rate by increasing the number of molecules that have sufficient kinetic energy to react.
