Question
Balance the equation:
Si(OH)4+NaBr → SiBr4+NaOH
- Si(OH)4+2NaBr → SiBr4+NaOH
- Si(OH)4+4NaBr → SiBr4+4NaOH
- Si(OH)4+NaBr → SiBr4+4NaOH
- Si(OH)4+2NaBr → SiBr4+2NaOH
Hint:
A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge are the same for both the reactants and the products.
The correct answer is: Si(OH)4+4NaBr → SiBr4+4NaOH
Balanced equation:
Si(OH)4+4NaBr → SiBr4+4NaOH
