Blast furnace, iron metal is obtained by reduction of haematite Fe2O3. 36 L of carbon monoxide CO are mixed with 80 g haematite Fe2O3, the products formed are

carbon dioxide gas CO2 and iron precipitate.

1. Write the balanced equation of the reaction that takes place.

2. Show that the above reaction mixture is stoichiometric.​

Imagine if during the cathode ray experiment, the size of the particles of the ray was the same as the size of the atom forming the cathode. which other model or scientific observation would have also been supported? 1. this would support dalton's postulates that proposed the atoms are indivisible because no small particles are involved. 2. this would support bohr's prediction about electrons moving in orbits having specific energy. 3. this would support bohr's prediction about electrons being randomly scattered around the nucleus in the atom. 4. this would support dalton's postulates that proposed that atoms combine in fixed whole number ratios to form compounds.
