When magnesium ion doesn't give any characteristics colour with the flame test as electronic transisitons do not give out visible light.
This reaction is decomposition. It is the breakdown of a compound into simpler and smaller elements.
Answer:
chongus because he's the only good one
Answer is 128.892 g.
moles (mol) = mass (g) / molar mass (g/mol)
According to the given data,
moles = 4.60 mol
mass = ?
molar mass = 28.02 g/mol
By substitution,
4.60 mol = mass / (28.02 g/mol)
mass = 4.60 mol x 28.02 g/mol
mass = 128.892 g
Hence, mass of 4.60 mol of N₂ is 128.892 g.
