Question

KMnO4→ O2 → SiO2→ K2SiO3 →H2SiO3

Answer 1

Ответ:

2KMnO4=K2MnO4+MnO2+O2

O2+Si=SiO2

2Mg+SiO2=Si+2MgO

Si+2H2=SiH4

SiH4+2NaOH=Na2SiO3+3H2O

Na2SiO3+CaCl2=CaSiO3+2NaCl

CaSiO3+2HCl+Na2CO3=H2SiO3+CaCO3+2NaCl

Answer 2

Looks like a chemical reaction sequence! You've got potassium permanganate (KMnO4) reacting to produce oxygen (O2), then silicon dioxide (SiO2) is involved, leading to potassium metasilicate (K2SiO3) and ultimately hydrogen silicate (H2SiO3). It's like a molecular journey! Anything specific you'd like to know or discuss about this sequence?
