Arrange the metals used in this experiment (including H2 and Ag) in order of decreasing reactivity (most reactive metal first).
1 answer:
Explanation:
According to the reactivity series chart, elements from high to lower reactivity are arranged as follows.
K, Na, Ca, Mg, Al, C, Zn, Fe, Sn, Pb, H, Cu, Ag, Au
So, using this standard reactivity chart of metals we will place the given metals in the order of decreasing reactivity as follows.
Na > Ca > Mg > Al > Zn > Fe > Sn > Pb > > Cu > Ag

Answer : The volume of consumed are,
L.
Explanation :
The balanced chemical reaction will be:
First we have to calculate the moles of Al.
Molar mass of Al = 27 g/mole
Now we have to calculate the moles of .
From the reaction we conclude that,
As, 4 mole of Al react with 3 moles of
So, 2 mole of Al react with moles of
Now we have to calculate the volume of consumed.
As we know that, 1 mole of substance occupies 22.4 liter volume of gas.
As, 1 mole of occupies 22.4 liter volume of
gas
So, mole of
occupies
liter volume of
gas
Therefore, the volume of consumed are,
L.
