Beryllium metal does not react with water or steam, even if the metal is heated to red heat. Reaction of beryllium with the halogens Beryllium metal reacts chlorine, Cl 2 , or bromine, Br 2 , to form the beryllium dihalides beryllium (II) chloride, BeCl 2 , and beryllium (II) bromide, BeBr 2 , respectively.
7/7/2013· general equation for the reaction of a metal with water if the metal Is more reactive than hydrogen. metal + water = metal hydroxide + hydrogen gas magnesium doesn''t react with liquid water but would react with steam (gaseous water)
Calcium Metal is available as disc, granules, ingot, pellets, pieces, powder, rod, wire, and sputtering target. Ultra high purity and high purity forms also include metal powder, submicron powder and nanoscale, quantum dots, targets for thin film deposition, pellets for evaporation and single crystal or polycrystalline forms.
As metal carbonates react with acid, a neutralisation reaction happens. Salt, water, and carbon dioxide are produced. This can be expressed in the following general equation: metal carbonate + acid → salt + water + carbon dioxide To test for carbon dioxide the
Metal-Acid Reactions Most metals react with dilute acids to form a salt and hydrogen. These reactions have the general formula: Example zinc + hydrochloric acid → zinc chloride + hydrogen Zn (s) + 2 HCl (aq) → ZnCl 2 (aq) + H 2 (g) More reactive metals
milk, sea water and various solid materials. It can also be used to determine the total hardness of fresh water provided the solutions used are diluted. The coined concentration of calcium and magnesium ions is considered to be the measure of water hardness.
Tests for carbonate ion, compounds, reactions, precipitates The carbonate ion is the anion of carbonic acid which is a weak acid.Some compounds of carbonate ion forms precipitates and some metal carbonates are soluble in water. Barium chloride or calcium

Commercial calcium carbonate products typically contain at least 95–98% CC, with the remainder being various metal oxides. CC for plastics may be ground from limestone (such as dolomite) or another natural raw source, or chemically precipitated into fine, uniform particles with predictable properties.
