If pressure is kept constant and the temperature of a gas is doubled, what will happen to the volume?

the volume will be doubled

Explanation: the expression from the question clearly indicates Charles' law. Charles' law states that volume is proportional to temperature at constant pressure. This simply means as one variable increase, the other variable will also increase. Please see attachment for mathematical explanation

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
