Question

СРОЧНО укажите гомогенную реакцию 1 SO2+NO2 2 No+O2 3 C+O2 a 1 b 2 3 c 1 2 3 d 3 e 1 2 какой металл реагирует с щелочью вытесняет водород a /Fe b /Al c/ Mg d/Cu 3/Au какая реакция в растворе идет до конца a CaCl2+Na2CO3 b AgNo3+KCl c NH4Cl+NaOh d NaNO3+BaCl2 e FeCl3+NaOh

Answer 1

Гомогенные реакции это 1 и 2 
SO2 + NO2 = SO3 + NO 
2NO + O2 = 2NO2
Ответ под буквой Е

Металл, который реагирует с щелочью и вытесняет водород, это Al. Т.е. ответ под буквой Б
NaOh + Al = Na2AlO2 + H2

В третьем задании, может вы "не" пропустили? Потому что все реакции, кроме реакции под буквой Д, идут до конца. 
а) CaCl2 + Na2CO3 = CaCO3↓ + 2NaCl
b) AgNO3+KCl = AgCl↓ + KNO3 
c) NH4Cl+NaOH = NH3↑ + H2O + NaCl
d) NaNO3+BaCl2 ≠ данная реакция невозможна, так как не образует газ, вода или осадок
e) FeCl3+3NaOH = Fe(OH)3↓ + 3NaCl

Answer 2

Homogeneous Reaction:

A homogeneous reaction is a chemical reaction in which all the reactants and products are in the same phase, either all in the gas phase, all in the liquid phase, or all in the solid phase. In the given reaction, we have a mixture of gases and solids, so it is not a homogeneous reaction.

Metal Reacting with Alkali:

The metal that reacts with alkali and displaces hydrogen is Aluminum (Al). When aluminum reacts with alkali, such as sodium hydroxide (NaOH), it forms aluminum hydroxide (Al(OH)3) and displaces hydrogen gas (H2) according to the following reaction:

2Al + 6NaOH -> 2Na3AlO3 + 3H2

Complete Dissociation in Solution:

A reaction that goes to completion or proceeds to the maximum extent in a solution is called a complete dissociation reaction. In the given options, the reaction that goes to completion in solution is c) NH4Cl + NaOH. When ammonium chloride (NH4Cl) reacts with sodium hydroxide (NaOH), it forms ammonia (NH3), water (H2O), and sodium chloride (NaCl) according to the following reaction:

NH4Cl + NaOH -> NH3 + H2O + NaCl

The other options, such as CaCl2 + Na2CO3, AgNO3 + KCl, NaNO3 + BaCl2, and FeCl3 + NaOH, do not undergo complete dissociation in solution.
