CHÚC BN HỌC TỐT :))))

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?

\(C_xH_yO_z+\left(x+\dfrac{y}{4}-\dfrac{z}{2}\right)O_2\rightarrow xCO_2+\left(\dfrac{y}{2}\right)H_2O\)

Cô có chỉnh sửa đề 1 chút cho phù hợp

\(\dfrac{4x+v-2z}{2}\)2xCO₂ + vH₂O

C_xHyO_Z +(x+y/4-z/2) O_{2 -> x}CO2 +y/2 H₂O

b)2CxHy + (2x-y)O2 → 2xCO2 + 2yH2O

c)2CmH2m-2+(3m-1)O2 → 2mCO2 + (2m-2) H2O

d)2CxHyOz+(2x+y-z)O2

→2xCO2 + 2yH2O
