Below is the word equation for this reaction: Calcium Carbonate + Hydrochloric Acid = Calcium Chloride + Carbon Dioxide + Water Below is the fully balanced chemical equation for this reaction. CaCo3 + HCl  CaCl2 + CO2 + H2O Aim The aim of this investigation is to find out whether the concentration of the acid affects the

! Isolation of the Components of BC Powder Introduction Aspirin‚ Caffeine and Salicylamide were extracted from an over-the-counter pain reliever (BC Powder). These components were separated by manipulating their solubilities by adjusting the acidity and basicity of the solution. By doing this‚ the three components were forced into conjugate acid (or base) forms‚ causing selective solubility in either an aqueous or organic solvent. These layers were then separated by use of a separation funnel

Introduction In this experiment‚ exo-norborneol was produced by a hydration of alkenes by using an acid and excess water. Hydration of alkenes is the acid-catalyzed addition of water to a carbon-carbon pi bond that leads to the formation of an alcohol. Norbornene is a bridged cyclic hydrocarbon‚ this molecule contains a double bond that induces significant ring strain‚ and therefore‚ it is highly reactive. In order for this reaction to occur‚ equilibrium must be established between the hydration

driveway. Furthermore‚ the grass seems to be growing more slowly up to 1 foot from the driveway. Question: Might grass growth be inhibited by salt? Introduction: The chemical components that make up salt are the fused elements of sodium and chloride (Editorial Board‚ 2012). If there is abundance or very little salts present in dissolve fluids‚ there could be interference with routine cell functions. Plants depend on water for fluids within the living cells. Too much salt disrupts the flow

reaction. A precipitate reaction happens when cations and anions of certain aqueous solutions react and combine forming a precipitate‚ which is an insoluble ionic solid. In this precipitate reaction we dissolved both chosen chemicals (powder Calcium Chloride dihydrate and powder Sodium Carbonate) in distilled water and then mixed them together in a single beaker. Finally we filtered this mixture and let all the water evaporate leaving behind solely the precipitate. In order to determine the amounts needed

Group 1 and 2 are willing to give. Therefore‚ out of all the main group elements‚ Halogens react vigorously with Group 1 and Group 2 metals. All the alkali metals react vigorously with halogens to produce salts‚ most important NaCl and KCl. Sodium Chloride is used as a preservative for meat and to melt the ice on the roads. KCl is important for plant fertilizers since potassium helps plant growth. The metal halides form white ionic crystalline solids. They are all soluble in water except LiF because

Go to a grocery store or big box store and pick up toilet cleaner containing hydrogen chloride (a.k.a. hydrochloric or muriatic acid). One brand‚ the Works‚ contains 20% hydrogen chloride. 2.) You don’t need too much just enough to reach about the 1/5 mark on a bottle 3.) Get a plastic bottle with a screw top. Do not use a metal or glass container! 5.) Go outside‚ far from

Introduction In chemistry‚ the term of an aqueous solution is defined as a substance that is soluble in water. For example‚ sodium chloride (NaCl) dissolves in water‚ or other known as table salt. In many cases when a substance is dissolved in water‚ it forms ions‚ an electrically charged atom. When this reaction occurs it is called an electrolyte at which the solution conducts electricity

an alkyl or acyl halide with a Lewis acid‚ or acylation‚ which is done with acid chlorides or anhydrides(Lefevre). Acylation was used because it does not have as many disadvantages aklyations reactions have such as polyalkylation‚ second electrophilic attacks‚ and the rearrangement of alkyl carbocation electrophile (McMurry). Acylation reactions require molar amounts of a Lewis catalyst‚ in our case Aluminum Chloride (AlCl 3) was used (Arata‚ Nakamura‚ & Shouji). Materials and Methods Reflux
