Moles(AL)/moles(CL2) = 2/3
moles(CL2) = 3/2 * 3.90
moles(CL2) = 5.85 mol
<span> so now we use the number of moles of NO 5.27 moles. use again the PV=nRT
R=62.36367(L mmHg K−1 mol−1)
T=35C + 273 = 308K
P=632 mm Hg
V=97.3 L
n=632*97.3/62.3636367*308=3.20145770868
Look at the mole ratio of NO to NO2 its 2:2 they share the same number of moles.
Atomic weight of each element in NO2
N:14 O:16
Molar Mass:(16*2)+(14*1)=46 g
Actual number of moles=3.20
Theortical number of moles=5.20
Percentage Yield=(Actual Yield/Theortical Yield)*100</span>
The correct answer is letter (d.) Mg, Ca, Sr, Ba
These four elements are found in Group 2 of the periodic table, which are alkaline metals, therefore they have the very similar properties because of their 2 valence electrons, which makes them reactive.
Na2SO4 and H2O are the products.
