Question

Mg+ 2HCL> MgCl2 + H2 what is the volume of H2 produced in cm3 when 0.5mol of Mg reacts with excess acid

Answer 1

hey mate here is pratyush to help you out from India....

1 mole Mg can produce 22.4L H2 gas
=>0.5 mol Mg can produce 11.2L gas

11.2L=11.2*1000cm³
=1.12*10^4cm³(answer)

hope it helps you...

be brainly

Answer 2

Magnesium reacts with hydrochloric acid to produce magnesium chloride.

It can be represented as:

Mg + 2 HCl  ---------> MgCl₂ + H₂

To calculate the volume of H₂:

• 1 mole Mg = 22.4 L H₂ gas

• So, 0.5 mol Mg = 11.2 L H₂gas

• 11.2 L = 11.2 × 1000 cm³

       = 1.12 × 10⁴cm³

Therefore, 1.12 × 10⁴cm³ of H₂ will be produced when 0.5 moles of Mg reacts with acid.
