Question

cân = PTHH sau

1) Fe(OH)₂+O₂--->Fe₂O₃+H₂O

2) Al(OH)₃--> Al₂O₃+H₂O

3) C_xH_yOz+O₂--> CO₂+H₂O

4) KMnO₄+HCl-->KCl+MnCl₂+Cl₂+h₂o

5) CnH₂n+O₂-->CO₂+H₂O

Answer 1

1) 4Fe(OH)2+O2--->2Fe2O3+4H2O

2) 2Al(OH)3--> Al2O3+3H2O

3) 2zCxHyOz+xO2--> 2xzCO2+yzH2O ( chưa chắc chắn)

4) 2KMnO4+16HCl-->2KCl+2MnCl2+5Cl2+8H2O

5) CnH2n+O2-->CO2+H2O ( không rõ đề)

Answer 2

1) 4Fe(OH)₂+O₂\(\rightarrow\)2Fe₂O₃+4H₂O

2) 2Al(OH)₃\(\rightarrow\)Al₂O₃+3H₂O

3) C_xH_yO_z+(x+\(\dfrac{y}{4}-\dfrac{z}{2}\))O₂\(\rightarrow\)xCO₂+\(\dfrac{y}{2}H_2O\)

4) 2KMnO₄+16HCl\(\rightarrow\)2KCl+2MnCl₂+5Cl₂+8H₂O

5) C_nH_2n+\(\dfrac{3n}{2}\)O₂\(\rightarrow\)nCO₂+nH₂O

Answer 3

Cái thứ 5 mik k hiểu lắm nên k làm được nha

1.4Fe(OH)₂+O₂----->2Fe₂O₃+4H₂O

2.2Al(OH)₃----->Al₂O₃+3H₂O

3.2zC_xH_yO_z+xO₂----->2xzCO₂+yzH₂O

4.2KMnO₄+16HCl----->2KCl+2MnCl₂+5Cl₂+8H₂O

Chúc bạn học tốt
