The channel cleaner, Drainex contains little pieces of aluminum which respond with scathing soft drink to create dihydrogen. What volume of dihydrogen at 20 °C and one bar will be delivered when 0.15g of aluminum responds?

solution:

Aluminum responds with scathing soft drink as per the response

 

The response of aluminum with scathing soft drink can be addressed as:

 

\[2Al\text{ }+\text{ }2NaOH\text{ }+\text{ }2H2O\text{ }\to \text{ }2NaAlO2\text{ }+\text{ }3H2\]

Thusly volume of hydrogen at STP delivered when 0.15g of Al reactsv

 

\[\begin{array}{*{35}{l}}

=0.15\text{ }x\text{ }3\text{ }x\text{ }22.4/54\text{ }=\text{ }187ml  \\

~  \\

Presently\text{ }P1~=\text{ }1\text{ }bar,  \\

~  \\

P2~=\text{ }1\text{ }bar  \\

~  \\

T1~=\text{ }273\text{ }K  \\

~  \\

T2~=\text{ }20\text{ }+\text{ }273\text{ }=\text{ }293\text{ }K  \\

~  \\

V1~=\text{ }187\text{ }ml  \\

~  \\

V2~=\text{ }x  \\

\end{array}\]

At the point when strain is held constant,then

 

\[V2~=\text{ }P1~V1~T2~/P2~T1\]

Or then again

 

\[x\text{ }=\text{ }1\text{ }X\text{ }187\text{ }X\text{ }293~/~0.987\text{ }X\text{ }273\text{ }=\text{ }201\text{ }ml\]

Thusly, 201 mL of dihydrogen will be delivered
