Study Notes
Balancing Chemical Equation
- The given chemical equation is: SiCl4 + H2O -> SiO2 + HCI
- To balance the equation, the correct coefficients are: SiCl4 + 2H2O -> SiO2 + 4HCI
- This equation indicates that one molecule of silicon tetrachloride (SiCl4) reacts with two molecules of water (H2O) to form one molecule of silicon dioxide (SiO2) and four molecules of hydrogen chloride (HCI)
