What is the correct formula of the salt formed in the neutralization reaction of hydrochloric acid with calcium hydroxide?

                CaCl

                CaCl2

                CaClH

                CaH2

                CaO

On an activity series chlorine is more active than bromine. What is a balanced chemical equation for the reaction between chlorine gas and aqueous sodium bromide?

                Cl + NaBr --> NaCl + Br

                Cl + NaBr --> Cl + NaBr

                Cl2 + NaBr --> NaCl + Br2

                Cl2 + NaBr2 --> NaCl2 + Br2

                Cl2 + 2 NaBr --> 2 NaCl + Br2

If 4.49 g NaNO3 (FW = 85.0 g/mol) is dissolved in enough water to make 250.0 mL of solution, what is the molarity of the sodium nitrate solution?

                18.0 M

                1.32 x 10

Explanation / Answer

1) cacl2

2)cl2+2nabr=2nacl+br2

3)molarity=(4.49/85)/0.25=2.11*10^-1M
