For each of the following, 1) underline the reactants and circle the products, 2) write a word equation and 3) write a symbolic equation.

1) When dissolved beryllium chloride reacts with silver nitrate dissolved in n , aqueous beryllium nitrate and silver chloride powder are made.

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 , 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 gas is put into contact with metal at high temperatures, calcium 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 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)

11) Solutions of magnesium nitrate and potassium phosphate react to form solid magnesium phosphate and a solution of potassium nitrate.

Aqueous magnesium nitrate + aqueous potassium phosphate →solid magnesium phosphate + aqueous potassium nitrate.

Mg(NO3)2(aq) + K3PO4(aq) → Mg3(PO4)2(s) + KNO3(aq)

12) When placed in liquid water, sodium metal reacts to produce aqueous sodium hydroxide and hydrogen gas.

Liquid water + sodium metal →aqueous sodium hydroxide + hydrogen gas

H2O(l) + Na(s) → NaOH(aq) + H2(g)
