Answer:
Explanation:Because of the delocalised electrons exposed above and below the plane of the rest of the molecule, benzene is obviously going to be highly attractive to electrophiles - species which seek after electron rich areas in other molecules.
Answer is: <span>b.20.0 L </span><span>liters of ammonia are needed to react completely.
</span>V(NO) = 30 L.
n(NO) = V(NO) ÷ Vm.
n(NO) = 30 L ÷ 22,4 L/mol.
n(NO) = 1,34 mol.
From chemical reaction: n(NO) : n(NH₃) = 6 : 4 (3 : 2).
n(NH₃) = 4 · 1,34 mol ÷ 6.
n(NH₃) = 0,892 mol.
V(NH₃) = 0,892 mol · 22,4 L/mol.
V(NH₃) = 20 L.
1.2 mm
a) Calculate the <em>volume</em> of the block
<em>V </em>= 50 g x (1 cm^3/8.64 g) = 5.79 cm^3
b) Calculate the <em>height</em> of the block
The formula for the volume (V) of a block is
<em>V = lwh
</em>
where
<em>l</em> = the length of the block
<em>w</em> = the width of the block
<em>h</em> = the height of the block
We can solve this formula for the height.
<em>h = V</em>/(<em>lw</em>)
∴ <em>h</em> = 5.79 cm^3/(10 cm x 5 cm) = 0.12 cm = 1.2 mm
