Given a chemical reaction: GeH4 + 3 GeF4 4 GeF3H
How many grams of GeH4 are necessary to produce exactly 100.0 grams of GeF3H?

You know how the first one if filled up like the objects do the same but with the other categories

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na

Idon't know hope someone you
