Question

ПОМОГИТЕ ПОЖАЛУЙСТА СРОЧНО НАДО Реакция в результате которой выделяется газ: 1) Cu + FeCL3 = 2) Cu + H2O2 + HCL = 3) Ba + H2O = 4) CaO + NO3 =

Answer 1

3 ) Ba + 2H2O = Ba(OH)2 + H2↑ ЭТО СТО ПУДОВ ГАЗ Н2  

Answer 2

Chemical Reactions Resulting in Gas Formation

1) Cu + FeCl3 =

The reaction between copper (Cu) and iron(III) chloride (FeCl3) does not result in the formation of a gas. Instead, it leads to a displacement reaction where copper displaces iron from iron(III) chloride to form copper(II) chloride and iron.

2) Cu + H2O2 + HCl =

The reaction between copper (Cu), hydrogen peroxide (H2O2), and hydrochloric acid (HCl) does not result in the formation of a gas. Instead, it leads to the oxidation of copper by hydrogen peroxide in the presence of hydrochloric acid.

3) Ba + H2O =

The reaction between barium (Ba) and water (H2O) does not result in the formation of a gas. Barium is a reactive metal, but it does not react with water at room temperature.

4) CaO + NO3 =

The reaction between calcium oxide (CaO) and nitrate (NO3) does not result in the formation of a gas. Calcium oxide is a basic oxide and does not directly react with nitrate to produce a gas.

These reactions do not result in the formation of gas as per the chemical properties of the substances involved. If you have any further questions or need assistance with anything else, feel free to ask!
