Metal A with halogen X forms a compound with the chemical formula AX2. This composition is due to heat, respectively
Reaction: (g) 22AX (s) + X → (s) 22AX 9 g of /, decomposes.
Whenever 91 2AX completely decomposes
Og/and 21 AX 29 ml of gas / and 12 2X. The atomic mass of
halogen X is many times the atomic mass of metal
A) Consider 12 liters.
