Question

Допоможіть будь ласка потрібно сьогодні Складіть формули оксидів за їх назвою: а) сульфур (VI) оксид б) ферум (II) оксид в) нітроген (V) оксид г) карбон (IV) оксид

Answer 1

А) SO3
б) FeO
в) N2O5
г) CO2

Answer 2

Formulas of Oxides Based on Their Names:

a) Сульфур (VI) оксид: The formula for sulfur (VI) oxide can be determined by understanding the valency of sulfur and oxygen. Sulfur has a valency of 6, and oxygen has a valency of 2. Therefore, the formula for sulfur (VI) oxide is SO3.

b) Ферум (II) оксид: The formula for iron (II) oxide can be derived from the valency of iron and oxygen. Iron has a valency of 2, and oxygen has a valency of 2. Therefore, the formula for iron (II) oxide is FeO.

c) Нітроген (V) оксид: The formula for nitrogen (V) oxide can be determined based on the valency of nitrogen and oxygen. Nitrogen has a valency of 5, and oxygen has a valency of 2. Therefore, the formula for nitrogen (V) oxide is N2O5.

г) Карбон (IV) оксид: The formula for carbon (IV) oxide can be established by considering the valency of carbon and oxygen. Carbon has a valency of 4, and oxygen has a valency of 2. Therefore, the formula for carbon (IV) oxide is CO2.
