cac bạn ơi dấu bằng ong rồi cách ra làm cái khác nhé ình viết sai
chỉ có phần chất tham gia phản ứng thôi
\(4Al+3O_2\underrightarrow{t^o}2Al_2O_3\)
\(4K+O_2\rightarrow2K_2O\)
\(2Al\left(OH\right)_3\underrightarrow{t^o}Al_2O_3+3H_2O\)
\(Al_2O_3+6HCl\rightarrow2AlCl_3+3H_2O\)
\(CaCl_2+Fe\left(OH\right)_3\rightarrow\) Không phản ứng
\(BaCl_2+H_2SO_4\rightarrow2HCl+BaSO_4\downarrow\)
1. \(2Al+3Fe\left(NO_3\right)_2\rightarrow2Al\left(NO_3\right)_3+3Fe\)
2. \(P_2O_5+3Ba\left(OH\right)_2\rightarrow Ba_3\left(PO_4\right)_2+3H_2O\)
3. \(Al\left(OH\right)_3+3HCl\rightarrow AlCl_3+3H_2O\)
4. \(Al_2\left(SO_4\right)_3+3Ca\left(OH\right)_2\rightarrow3CaSO_4+2Al\left(OH\right)_3\)
5. \(Fe_3O_4+8HCl\rightarrow FeCl_2+2FeCl_3+4H_2O\)
6. \(Mg\left(NO_3\right)_2\underrightarrow{t^o}MgO+2NO_2+\dfrac{1}{2}O_2\)
7. \(2xFe+yO_2\underrightarrow{t^o}2Fe_xO_y\)
8. \(CH_4+2O_2\underrightarrow{t^o}CO_2+2H_2O\)
9. \(C_2H_6O+3O_2\underrightarrow{t^o}2CO_2+3H_2O\)
Bạn tham khảo nhé!
\(1.Al+Fe\left(NO_3\right)_2--->Al\left(NO_3\right)_2+Fe\)
\(2.P_2O_5+3Ba\left(OH\right)_2--->Ba_3\left(PO_4\right)_2+3H_2O\)
\(3.Al\left(OH\right)_3+3HCl--->AlCl_3+3H_2O\)
\(4.Al_2\left(SO_4\right)_3+3Ca\left(OH\right)_2--->3CaSO_4+2Al\left(OH\right)_3\downarrow\)
\(5.Fe_3O_4+8HCl--->FeCl_2+2FeCl_3+4H_2O\)
\(6.2Mg\left(NO_3\right)_2\overset{t^o}{--->}2MgO+4NO_2+O_2\)
\(7.xFe+\dfrac{y}{2}O_2\overset{t^o}{--->}Fe_xO_y\)
\(8.CH_4+2O_2\overset{t^o}{--->}CO_2+2H_2O\)
\(9.C_2H_6O+3O_2\overset{t^o}{--->}2CO_2+3H_2O\)
Của bạn nè:
a, Al2(SO4)3 + 3BaCl2 \(\rightarrow\) 2AlCl3 + 3BaSO4
b, 2Al(OH)3 \(\rightarrow\) Al2O3 + 3H2O
c, 4Al + 3O2 \(\rightarrow\) 2Al2O3
d, BaCl2 + 2AgNO3 \(\rightarrow\) Ba(NO3)2 + 2AgCl
e, Ca(OH)2 + 2HCl \(\rightarrow\) CaCl2 +2H2O
f, 3Fe3O4 + 8Al \(\rightarrow\) 3Fe + 4Al2O3
g, Ca(OH)2 + CO2 \(\rightarrow\) CaCO3 + H2O
\(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\)a) Al2(SO4) + 3BaCl2 -> 2AlCl3 + 3BaSO4
b) 2Al(OH)2 -> Al2O3 + 3H2O
c) 4Al +3O2 -> 2Al2O3
d) BaCl2 + 2AgNO3 -> Ba(NO3)2 + 2AgCl
e) Ca(OH)2 + 2HCl -> CaCl2 +2H2O
f) 3Fe3O4 +8Al -> 9Fe + 4Al2O3
g) Ca(OH)2 + CO2 -> CaCO3 + H2O
