I do not know i am doing this for the points
Answer: This is because the number of shell increases .
Explanation: On moving from left to write on the periodic table the reactivity of non metals increases because number of shells increases and the force with which the nucleus hold electrons decreases.

products are copper and aluminium chloride
reactants are aluminium and copper chloride
Explanation:
products are formed at the end of a reaction
reactants are what's reacting to form the products ie the things at the start of the equation
Answer:
Number of moles is 3.0moles
Explanation:
Volume (v) = 67.2L
Pressure at STP = 1atm
Temperature at STP = 273.15K
R = 0.082J/mol.K
Number of moles (n) = ?
From ideal gas equation,
PV = nRT
P = pressure
V = volume of the gas
n = number of moles
R = ideal gas constant
T = temperature of the gas
PV = nRT
solving for n,
n = PV / RT
n = (1.0 * 67.2) / (0.082 * 273.15)
n = 67.2 / 22.398
n = 3.0 moles
The number of moles present is 3.0
