Question

Answer 1

Khí mùi hắc thu được là SO₂.

Ta có: \(n_{SO_2}=\dfrac{5,6}{22,4}=0,25\left(mol\right)\)

a, PT: \(2Al+6H_2SO_{4\left(đ\right)}\underrightarrow{t^o}Al_2\left(SO_4\right)_3+3SO_2+6H_2O\)

_____1/6_____0,5_________________0,25 (mol)

b, \(m_{Al}=\dfrac{1}{6}.27=4,5\left(g\right)\)

c, Ta có: \(m_{H_2SO_4}=0,5.98=49\left(g\right)\)

\(\Rightarrow m_{ddH_2SO_4}=\dfrac{49}{98\%}=50\left(g\right)\)

\(\Rightarrow V_{ddH_2SO_4}=\dfrac{50}{1,84}\approx27,17\left(ml\right)\)
