Shreya buys a new Seadoo. She goes 12 km north from the beach. She jumps and wakes for 6 km to the east. Then chases a boat 10 km north. What distance did she cover? What was her displacement?

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

Wow that a lot of text for my tiny so i no wanna answer

Not a  mixture of two common elements that can be separated by physical means.

They make up examples of physical properties
