Answer:
0.3 moles of H2 will be produced.
Explanation:
Balanced reaction: 2 Al + 6 HCl → 2 AlCl3 + 3 H2
Given Al mass = 5.4 g, we know Mr of Al is 27
Using the formula:
moles = mass / Mr
moles of Al = 5.4 / 27
moles of Al = 0.2 moles
Here we see that "2" molar mass before Al; so in this reaction, "1" molar mass will have [(0.2)/2] = 0.1 moles. He see "3" molar mass before H2, therefore moles of H2 is (3 * 0.1) = 0.3 moles.

Explanation:
At convergent plate boundaries two plates are moving towards one another and different scenarios are in play.
Most importantly, at these margins the crust is being destroyed.
- At continental - continental crust margin, there is an uplift because the density of the two crust is similar and lesser than that of the mantle below.
- At continental - oceanic crust margin, subduction zones are found where the denser oceanic crust sinks beneath into the mantle.
- This is also the case with ocean - ocean convergence zone.
Some of the features found at this margin include, oceanic trenches, accretionary wedges, volcanic islands, earthquakes
