I need help with Chemistry homework.. I don't know how to write formulas..Please help me!
Write the formulas for silicon dioxide.
For some, such as silicon dioxide, the name tells you. Write the symbols.
Si and O. The name says DI oxide so put 2 for O as a subscript and the formula is SiO2.
SiO2 is a formula but it says formula(s)
SiO2 is THE formula for silicon dioxide. That's it. That's the only formula for silicon dioxide.
Sure! I can help you with that. The formula for silicon dioxide can be determined by knowing the chemical symbols and the valency (or charge) of each element. In the case of silicon dioxide, it is composed of silicon (Si) and oxygen (O).
To write the formula for silicon dioxide, you need to consider the valency of each element. Silicon has a valency of +4, meaning it can form four bonds with other elements. Oxygen has a valency of -2, meaning it can form two bonds with other elements.
Since the total valency of silicon needs to balance with the total valency of the oxygen atoms in the compound, you need two oxygen atoms to balance the four bonds of silicon. Therefore, the correct formula for silicon dioxide is SiO2.
To determine the formula of a compound, it is important to know the valency of the elements involved. You can find the valency of elements in the periodic table or in a chemistry reference book. Understanding the valency and balancing the charges is key to writing correct chemical formulas.
