Question

Ca0; SO3; Mn2O7; CO2; Zns;​

Answer 1

Ответ:

Ca(+2)O(-2), S(+6)O3(-2), Mn2(+7)O7(-2), C(+4)O2(-2), Zn(+2)S(-2)

Объяснение:

У Кислорода в соединениях проявляется степень окисления -2

У Кальция и Цинка постоянная степень окисления +2

У Углерода, Марганца и Серы во втором соединении определяем с.о. по Кислороду

Answer 2

Ca0, SO3, Mn2O7, CO2, and Zns are chemical formulas representing different compounds. Here's some information about each compound:

Ca0 (Calcium Oxide):

- Calcium oxide, also known as quicklime or burnt lime, is a white, caustic, alkaline crystalline solid. - It is produced by heating calcium carbonate (CaCO3) at high temperatures, causing it to decompose and release carbon dioxide (CO2). - Calcium oxide is commonly used in various industrial applications, including the production of cement, steel, and glass. - The chemical formula for calcium oxide is CaO.

SO3 (Sulfur Trioxide):

- Sulfur trioxide is a chemical compound composed of one sulfur atom and three oxygen atoms. - It is a colorless liquid that readily reacts with water to form sulfuric acid (H2SO4). - Sulfur trioxide is an important industrial chemical used in the production of sulfuric acid, which is widely used in various industries. - The chemical formula for sulfur trioxide is SO3.

Mn2O7 (Manganese Heptoxide):

- Manganese heptoxide is a highly reactive compound composed of two manganese atoms and seven oxygen atoms. - It is a dark red solid that is a powerful oxidizing agent and can react violently with organic compounds. - Manganese heptoxide is primarily used as an oxidizing agent in organic synthesis and laboratory experiments. - The chemical formula for manganese heptoxide is Mn2O7.

CO2 (Carbon Dioxide):

- Carbon dioxide is a colorless, odorless gas composed of one carbon atom and two oxygen atoms. - It is a natural component of the Earth's atmosphere and is produced by various natural and human activities, including respiration, combustion, and industrial processes. - Carbon dioxide plays a crucial role in the Earth's climate system and is a greenhouse gas that contributes to global warming. - The chemical formula for carbon dioxide is CO2.

Zns (Zinc Sulfide):

- Zinc sulfide is a compound composed of one zinc atom and one sulfur atom. - It occurs naturally as the mineral sphalerite and is commonly used as a pigment in various applications, including paints, plastics, and ceramics. - Zinc sulfide is also used in the production of phosphors for fluorescent lights and cathode ray tubes. - The chemical formula for zinc sulfide is ZnS.
