Phương trình số 1 là H2O hay là H2O2 vậy bạn?

Mk nhớ là đốt cháy hợp chất hữa cơ thì chỉ cho CO2 và H2O thôi mà?

Trả lời :

a) \(CO_2+C\underrightarrow{t^{\text{o}}}2CO\)

b) \(2H_2O_2\underrightarrow{\text{xt }MnO_2}2H_2O+O_2\)

c) \(3O_2\underrightarrow{\text{tia UV}}2O_3\)

d) \(N_2+O_2\underrightarrow{t^{\text{o}},\text{ xt }PtO_2}2NO\)

a) \(CO_2+C\underrightarrow{t^o}2CO\)

b) \(2H_2O_2\underrightarrow{MnO_2}2H_2O+O_2\uparrow\)

c) \(3O_2\underrightarrow{\text{tia cực tím}}2O_3\)

d) \(N_2+O_2\underrightarrow{t^o, MnO_2}2NO\)

\(2C_xH_yO_z+\dfrac{4x+y-2z}{2}O_2\underrightarrow{t^o}2xCO_2+yH_2O\)

\(2C_xH_yO+\dfrac{4x+y-2}{2}O_2\underrightarrow{t^o}2xCO_2+yH_2O\)
