Question

a. Al+H2SO4----->

b. Na+H2O------->

c. CO+Fe3O4------->

d. H2+Al2O3------>

Answer 1

\(2Al+3H_2SO_4\rightarrow Al_2\left(SO_4\right)_3+3H_2\\ Na+H_2O\rightarrow NaOH+\frac{1}{2}H_2\\ 4CO+Fe_3O_4\underrightarrow{t^o}3Fe+4CO_2\\ H_2+Al_2O_3\underrightarrow{t^o}kpu\)

Answer 2

a. 2Al + 3H2SO4 --> Al2(SO4)3 + 3H2

Answer 8

Answer 9

a. 2Al+3H₂SO₄-----> Al₂(SO₄)₃ +3H₂

b. 2Na+2H₂O-------> 2NaOH+H₂↑

c. 4CO+Fe₃O₄------->3Fe+4CO₂↑

d. 3H₂+Al₂O_3------> 2Al+3H₂O

Answer 10

a, \(2Al+3H_2SO_4\rightarrow Al_2\left(SO_4\right)_3+3H_2\uparrow\)

b,\(2Na+2H_2O\rightarrow2\text{NaOH + H2}\uparrow\)

c,\(\text{4CO + Fe_3O_4 }\underrightarrow{to}\text{4 CO_2 + 3Fe}\)

d,\(\text{3H_2 + Al_2O_3 }\underrightarrow{to}\text{3H_2O + 2Al}\)

Answer 11

2Al+ 3H2SO4-----> Al2(SO4)3 + 3H2
2Na + 2H2O----->2NaOH + H2
4CO + Fe3O4 -----> 3Fe + 4CO2
3H2 + Al2O3------> 2Al + 3H2O

Answer 12

H2 + Al2O3 ko có phản ứng nha
