Answer:
P2I4 is otherwise known as "<em>Diphosphorus Tetraiodide</em>"
Answer:
A) SiO2 is the limiting reactant
B) Theoretical yield= 72333.3g
C) % yield =91.5%
Explanation:
SiO2(s) + 2C(s) --------------> Si(s) + 2CO(g)
n(SiO2)= 155000/60 = 2583.33 mols
n(C)= 79000/12= 3291.66 mols
a)SiO2 is the limiting reactant
According to the balanced reaction equation,
60g of SiO2 produced 28g of SiO2
155000g of SiO2 will produce 155000×28/60= 72333.3g
Therefore theoretical yield of Si= 72333.3g
% yield= 66200/72333.3×100/1 =91.5%
Vinegar is a mixture because other thing are added to make a whole new thing
1 mole ---------- 22.4 L at ( STP)
? moles -------- 75.8 L
75.8 x 1 / 22.4 => 3.3839 L
