when iron and oxygen the reactin form Fe2O3 balance equation for this is <span>4Fe + 3O2---> 2Fe2O3
9moles of O2 are needed to produce 6mol of Fe2O3 since the ratio of oxygen to iron(II)oxide is 3:2
hope its help</span>
Answer:
is there a way of reducing light pollution at the edges of a forest work?
The right answer is 271.78 degrees for cyclohexane.
For each liquid there is a precise relationship between pressure and boiling temperature, we can define the boiling temperature as the moment when the first bubble of vapor appears on the surface of a liquid.
Explanation:
More is the electronegativity of atoms attached to the alpha carbon atom more will be the attraction of electron towards it. As a result, release of hydrogen ion will be easier.
Therefore, there will be increased in acidity of the compound.
Since, fluorine, chlorine and bromine are all group 17 elements and fluorine is more reactive than chlorine. On the other hand, chlorine is more reactive than bromine.
Hence, ability to attract the electrons towards itself will be maximum in fluorine and least in bromine.
Therefore, decreasing order of acidity of the given compounds is as follows.
