  • question_answer How many moles of lead (II) chloride will be formed from a reaction between 6.5 g of PbO and 3.2 g of HCl?

    A)  0.333        

    B)  0.011

    C)  0.029        

    D)  0.044

    Correct Answer: C

    Solution :

     \[PbO+2HCl\xrightarrow{{}}PbC{{l}_{2}}+{{H}_{2}}O\] \[{{n}_{PbO}}=\frac{6.5}{223}=0.029\] \[{{n}_{HCl}}=\frac{3.2}{36.5}=0.087\]
    PbO gives \[PbC{{l}_{2}}\] HCl gives \[PbC{{l}_{2}}\]
    Moles 0.029  0.029 0.087     0.048
    \[\Rightarrow \]\[{{n}_{PbC{{l}_{2}}}}=0.029\]
