Question

Молю памогите Расставьте коэффициенты в схемах химических реакций и определите тип реакции. А) SO2 + H2O = H2SO3 Б) СО2 + Zn = ZnO + C В) KNO3 = KNO2 + O2 Г) CaCL2 + Na2CO3 = CaCO3 + NaCL Д) H2 + N2 = NH

Answer 1

Объяснение:

SO2+H2O=H2SO3 (соединение)

CO2+2Zn=2ZnO+C (замещение)

2KNO3=2KNO2+O2 (разложение)

CaCl2+Na2CO3=CaCO3+2NaCl (обмен)

3H2+N2=2NH3 (соединение)

Answer 2

A) SO2 + H2O = H2SO3

The given chemical equation is the reaction between sulfur dioxide (SO2) and water (H2O) to form sulfurous acid (H2SO3). This is a combination reaction where two or more substances combine to form a single product.

B) CO2 + Zn = ZnO + C

The given chemical equation is the reaction between carbon dioxide (CO2) and zinc (Zn) to form zinc oxide (ZnO) and carbon (C). This is a displacement reaction where one element displaces another element in a compound.

C) KNO3 = KNO2 + O2

The given chemical equation is the decomposition of potassium nitrate (KNO3) into potassium nitrite (KNO2) and oxygen gas (O2). This is a decomposition reaction where a single compound breaks down into two or more simpler substances.

Г) CaCl2 + Na2CO3 = CaCO3 + NaCl

The given chemical equation is the reaction between calcium chloride (CaCl2) and sodium carbonate (Na2CO3) to form calcium carbonate (CaCO3) and sodium chloride (NaCl). This is a double displacement reaction where the positive ions of two compounds exchange places.

Д) H2 + N2 = NH3

The given chemical equation is the reaction between hydrogen gas (H2) and nitrogen gas (N2) to form ammonia (NH3). This is a combination reaction where two or more substances combine to form a single product.
