Question

Mg (s) + 2HCl (aq) → MgCl2 (aq) + H2 (g)

If you start with 4.50 grams of Magnesium (Mg), how many grams of Hydrogen gas (H2) will you theoretically...

Answer 1

Step-by-step explanation:

So you should obtain 0.1875 moles of H2 The theoretical yield of H2, in grams, can be found by multiplying the 0.1875 moles by the molar mass of H2 (2 grams/mole). We would expect, and love to find, 0.37g in our possession.

Answer 2

Mg(c) + 237shi (4z) ¥at h2)
