Question

Mg(s)+2HCl(aq) → MgCl2(aq)+H2(g)


In an experiment, a student places a small piece of pure Mg(s) into a beaker containing 250.mL of 6.44MHCl(aq) . A reaction occurs, as represented by the equation above.

The student collects the H2(g) produced by the reaction and measures its volume over water at 298 K after carefully equalizing the water levels inside and outside the gas-collection tube. The volume is measured to be 45.6mL . The atmospheric pressure in the lab is measured as 765 torr , and the equilibrium vapor pressure of water at 298 K is 24 torr .


Calculate the following.


(i) The pressure inside the tube due to the H2(g)

(ii) The number of moles of H2(g) produced in the reaction

Answer 1

Answer:

it is neutralization reaction
