B) For the following reaction: (3 points) CAH10(g) + Cl2(g) → C HỌCI(1) + HCl(9)00
i) Write the K expression (K equation)
given the following:
K-10 (CH.]=0.50 mol/L [HCI] = 0.25 mol/L

Only one reactant yields 2 or more products. meaning you will only have 1 product and it will break down into 2 or more products. eg. h2o -> h2 + o2

The answer is c) pyrite

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
