Answer:
model of mountain formation
Explanation:
The formation of mountains takes millions of years. This formation of mountains involves so much processes that do not occur quickly.
Hence, a model that can adequately show something that happens very slowly is the model for the formation of mountains.
Water: hydrogen bonding
carbon tetrafluoride: dispersion or Van del Waals
dichloromethane: dipole-dipole
If it's the liquid inside:
mercury
The reaction is given as
Fe2O3 (s)+ 3CO(g)--->3CO2(g)+ 2Fe(s)
No.of moles=mass in gram/molar mass
As for Fe mole =156.2g/55.847=2.7969~2.797
The ratio b/w CO and Fe is 3:2
Moles of CO needed= 2.797x3/2=4.1955
Mass of CO needed= 4.195mol x 28.01g/mol= 117.515g
