Part C Close the simulation window for carbon dioxide and return to the Cool Molecules Explore page.
Next, click Cand H in the periodic table and repeat the process for methane (CH4). In the table below, record the names of its vibrational modes
and describe the vibration of the molecule in each mode. Also record the number of unique possible states for each mode.

The answer would be

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

Answer//the law of conservation of mass.;
