To determine the number of moles of HCl from 2 moles of H2, we take stoichiometry to solve this problem. The balanced equation is 2HCl= H2+Cl2 Using stoichiometry, the expression becomes 2 mole H2*(2 molHCl/1 mole H2). The answer is 4 moles.

A)The plates are all moving in the same direction
nevsk [136]
I believe the answer is C) there is an obvious reasoning for this all you have to do is eliminate answers that don't seem right for example, A)the plates are all moving the same direction every plate moves in different directions. B) The plates are all the same size. Well, it's really obvious that that is not true because every plate has its different shape and size. D) where two plates meet, they always move apart. If this were true, then we would never have earthquakes when plates meet earthquakes happen. so there for the answer is C)
