Fill in the systematic names of the following chemical compounds.
Note: for compounds containing hydrogen, you may give the common name instead.
| molecular formula | name of compound |
| :---------------- | :--------------- |
| $SiO _2$ | |
| $SO _3$ | |
| $SO _2$ | |
| SiO | |
| $NH _3$ | |
Answer (1)
S i O 2 is silicon dioxide.
S O 3 is sulfur trioxide.
S O 2 is sulfur dioxide.
S i O is silicon monoxide.
N H 3 is ammonia.
The systematic names of the chemical compounds are:
S i O 2 : silicon dioxide
S O 3 : sulfur trioxide
S O 2 : sulfur dioxide
S i O : silicon monoxide
N H 3 : ammonia
Explanation
Problem Analysis We need to systematically name the given chemical compounds based on their molecular formulas. For compounds containing hydrogen, we can use the common name.
Naming S i O 2 S i O 2 is composed of silicon and oxygen. The systematic name is silicon dioxide.
Naming S O 3 S O 3 is composed of sulfur and oxygen. The systematic name is sulfur trioxide.
Naming S O 2 S O 2 is composed of sulfur and oxygen. The systematic name is sulfur dioxide.
Naming S i O S i O is composed of silicon and oxygen. The systematic name is silicon monoxide.
Naming N H 3 N H 3 is composed of nitrogen and hydrogen. The common name is ammonia.
Examples
Understanding chemical nomenclature is crucial in various fields, such as environmental science, where identifying pollutants like sulfur dioxide ( S O 2 ) helps in assessing air quality and implementing mitigation strategies. In materials science, knowing the composition of silicon dioxide ( S i O 2 ) is essential for developing advanced ceramics and semiconductors. In agriculture, understanding the properties of ammonia ( N H 3 ) is vital for optimizing fertilizer use and minimizing environmental impacts. These examples highlight how chemical nomenclature bridges theoretical knowledge with practical applications, enabling informed decision-making and innovation across diverse disciplines.
