(Theo mình pt số 3 sản phẩm là:\(FeCl_{\dfrac{2y}{x}}\))
\(2C_nH_{2n-2}+\left(3n-1\right)O_2\underrightarrow{o}2nCO_2+\left(2\left(n-1\right)\right)H_2O\)
\(2C_nH_{2n+2}+\left(3n+1\right)O_2\underrightarrow{o}2nCO_2+\left(2\left(n+1\right)\right)H_2O\)
\(Fe_xO_y+2yHCl\rightarrow xFeCl_{\dfrac{2y}{x}}+yH_2O\)
\(4C_xH_yN_t+\left(4x+y\right)O_2\underrightarrow{o}4xCO_2+2yH_2O+2tN_2\)
a)CxHy+(x+\(\dfrac{y}{4}\))O2->xCO2+\(\dfrac{y}{2}\)H2O
b)CxHyOz+(x+\(\dfrac{y}{4}\)-\(\dfrac{z}{2}\))O2->xCO2+\(\dfrac{y}{2}\)H2O
c)FexOy+yCO->xFe+yCO2
d)Fe3O4+8HCl->FeCl2+2FeCl3+4H2O
1) CxHyOz +\(\left(x+\frac{y}{4}-\frac{z}{2}\right)\)O2----> xCO2 +\(\frac{y}{2}\)H2O
2) CnH2n-6 + \(\left(n+\frac{n-3}{4}\right)\)O2 ----> nCO2 + \(\frac{y}{2}\)H2O
1) CxHyOz +\(\left(x+\frac{y}{4}-\frac{z}{2}\right)\) O2----> xCO2 + \(\frac{y}{2}\)H2O
1) 2CnH2n + 3nO2 -> 2nCO2 + 2nH2O
2) 2CnH2n+2 + (3n+1)O2 -> 2nCO2 + (2n+2)H2O
3) 2CnH2n-2 + (3n-1)O2 -> 2nCO2 + (2n-2)H2O
4) 2CnH2n-6 + (3n-3)O2 -> 2nCO2 + (2n-6)H2O
5) 2CnH2n+2O + (3n+1)O2 -> 2nCO2 + (2n+2)H2O
6) 4CxHy + (4x+y)O2 -> 4xCO2 + 2yH2O
7) 4CxHyOz + (4x+y-2z)O2 -> 4xCO2 + 2yH2O
8)4CxHyOzNt +(4x+y-2z)O2 ->4xCO2 +2yH2O +2tN2
9) 4CHx + (2y+x)O2 -> 4COy + 2xH2O
10) 2FeClx + (3-x)Cl2 -> 2FeCl3
2)CnH2n+2+(3n+1)/2O2 -> nCO2+(n+1)H2O
3)CnH2n-2+(3n-1)/2O2->nCO2+(n-1)H2O
4)CnH2n-6+3/2(n-1)O2 -> nCO2+(n-3)H2O
a, FeO+CO-----------> Fe+CO2
b, FeO2 +CO-----------> FeO+CO2
c, C2H4 + 3O2 ------------> 2CO2+ 2H2O
1) 4CxHy + (4x+y)O2 → 4xCO2 + 2yH2O
2) 2CnH2n + 3O2 → 2nCO2 + 2nH2O
3) 2CnH2n+2 + (3n+1)O2 → 2nCO2 + (2n+2)H2O
4) 2CnH2n-2 + (3n-1)O2 → 2nCO2 + (2n-2)H2O
5) 4CxHyOz + (4x+y-2z)O2 → 4xCO2 + 2yH2O
6) 4CxHyOzNt + (4x+y-2z)O2 → 4xCO2 + 2yH2O +2tN2
7) 4Mg + 5H2SO4 (Đặc, nóng) → 4MgSO4 + H2S + 4H2O
8) 3Zn + 4H2SO4 (Đặc, nóng) → 3ZnSO4 + S + 4H2O
9) 8Mg + 18HNO3 (Loãng) → 8Mg(NO3)2 + 2NH3 + 6H2O
10) Fe + HNO3 (Loãng) → Fe2(SO4)3 + N2 + H2O (Phương trình có vấn đề)
a) FexOy + yH2 → xFe + yH2O
b) 2CxHy +\(\frac{4x-y}{2}O_2\) → 2xCO2 + yH2O
c) 2CxHyOz + \(\frac{4x+y-2z}{2}\)O2 → 2xCO2 + yH2O
d) FexOy + 2yHCl → xFeCl2y/x + yH2O
đ) CnH2n+2 + \(\frac{3n+1}{2}\)O2 → nCO2 + (n+1)H2O
e) 2CnH2n + 3nO2 → 2nCO2 + 2nH2O
f) CnH2n - 2 + \(\frac{3n-1}{2}\)O2 → nCO2 + (n-1)H2O
