Aqueous beryllium chloride + aqueous silver nitrate  aqueous beryllium nitrate + solid silver chloride BeCl2(aq) + AgNO3(aq)  Be(NO3)2(aq) + AgCl(s) 2) When liquid isopropanol (C3H8O) burns in oxygen gas, carbon dioxide gas and liquid water are produced. liquid isopropanol (C3H8O) + oxygen gas carbon dioxide gas + liquid water C3H8O(l) + O2(g) CO2(g) + H2O(l) 3) When dissolved sodium hydroxide reacts with sulfuric acid, aqueous sodium sulfate and water are formed. aqueous sodium hydroxide + sulfuric acid  aqueous sodium sulfate + water NaOH(aq) + H2SO4(aq)  Na2SO4(aq) + H2O(l) 4) When fluorine gas is put into contact with calcium metal at high temperatures, calcium fluoride powder is created. Fluorine gas + solid calcium solid calcium fluoride F2(g) + Ca(s) CaF2(s) 5) When hydrogen gas and oxygen gas react, they form liquid water. hydrogen gas + oxygen gas react → liquid water H2(g) + O2(g) → H2O(l) 6) Iron metal reacts with aqueous lead(II) sulfate to form aqueous iron(II) sulfate and lead metal. Solid iron + aqueous lead(II) sulfate → aqueous iron(II) sulfate + solid lead Fe(s) + PbSO4(aq) → FeSO4(aq) + Pb(s) 7) Phosphoric acid and aqueous calcium hydroxide react to form a calcium phosphate precipitate and liquid water. Phosphoric acid + aqueous calcium hydroxide → solid calcium phosphate + liquid water. H3PO4(aq) + Ca(OH)2(aq) → Ca3(PO4)2(s) + H2O(l) 8) Nitrogen gas and oxygen gas react to form gaseous dinitrogen pentoxide. Nitrogen gas + oxygen gas → gaseous dinitrogen pentoxide N2(g) + O2(g) → N2O5(g) 9) Aqueous potassium iodide reacts with bromine to form aqueous potassium bromide and iodine. Aqueous potassium iodide + bromine →aqueous potassium bromide + iodine. KI(aq) + Br2(l) → KBr(aq) + I2(s) 10) Nitrogen gas and hydrogen gas react to form gaseous nitrogen trihydride. Nitrogen gas + hydrogen gas →gaseous nitrogen trihydride. N2(g) + H2(g) → NH3(g)
