The most reactive metal on the periodic table is Francium, However, Francium is an artificial element and only minimal quantities have been produced, so for all practical purposes, the most reactive metal available is Cesium, in the alkali metal family.
ANSWER In theory, Francium, in practice the Cesium
Answer: 1.8 moles Fe and 2.7 moles are produced.
Explanation:
The balanced chemical reaction is:
According to stoichiometry :
3 moles of require 1 mole of
Thus 2.7 moles of will require=
of
Thus is the limiting reagent as it limits the formation of product and
is the excess reagent.
As 3 moles of give = 2 moles of
and 3 moles of
Thus 2.7 moles of will give =
of
and
of
Thus 1.8 moles Fe and 2.7 moles are produced.
Answer: The pressure required is 0.474 atm
Explanation:
Boyle's Law: This law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.
(At constant temperature and number of moles)
The equation is,
where,
= initial pressure of gas = 1.0 atm
= final pressure of gas = ?
= initial volume of gas =
= final volume of gas =
(
Now put all the given values in the above equation, we get:
The pressure required is 0.474 atm
