Answer 1

Ответ:

2AgNO3+CaCl2=Ca(NO3)2+2AgCl

В результате реакции между нитратом серебра и хлоридом кальция получается нитрат кальция и хлорид серебра, выпадающий в осадок.

Это показательная реакция на хлорид йон. Реакция обмена.

К окислительно-восстановительным не относится поскольку реагенты не меняют степень окисления.

Answer 2

Balancing Chemical Equation and Identifying Reaction Type

To balance the chemical equation and identify the reaction type for the given reaction AgNO3 + CaCl2, we can follow these steps:

1. Write the unbalanced equation: AgNO3 + CaCl2 = 2. Balance the equation by adding coefficients to the reactants and products. 3. Identify the type of reaction (e.g., synthesis, decomposition, single displacement, double displacement, combustion, etc.). 4. Determine if the reaction is an oxidation-reduction (redox) reaction.

Let's proceed with balancing the given chemical equation and identifying the reaction type.

Balancing the Chemical Equation

The unbalanced chemical equation is: AgNO3 + CaCl2 =

To balance the equation, we need to ensure that the number of each type of atom is the same on both sides of the equation. Let's balance the equation step by step.

First, let's write the balanced chemical equation: 2AgNO3 + CaCl2 = 2AgCl + Ca(NO3)2

The balanced equation is: 2AgNO3 + CaCl2 = 2AgCl + Ca(NO3)2

Identifying the Reaction Type

The given chemical equation represents a double displacement reaction, also known as a metathesis reaction. In this type of reaction, the positive and negative ions of two ionic compounds exchange places to form two new compounds.

Determining if the Reaction is Oxidation-Reduction (Redox)

In a redox reaction, there is a transfer of electrons between the reactants. To determine if the given reaction is a redox reaction, we need to analyze the oxidation states of the elements involved.

In the balanced equation 2AgNO3 + CaCl2 = 2AgCl + Ca(NO3)2, the oxidation states of the elements involved are as follows: - Ag: +1 in AgNO3 and 0 in AgCl - N: +5 in AgNO3 and -3 in Ca(NO3)2 - Ca: +2 in CaCl2 and +2 in Ca(NO3)2 - Cl: -1 in AgCl and -1 in CaCl2

Based on the changes in oxidation states, it is evident that the given reaction involves a transfer of electrons and is therefore an oxidation-reduction (redox) reaction.

In summary, the balanced chemical equation 2AgNO3 + CaCl2 = 2AgCl + Ca(NO3)2 represents a double displacement reaction and is classified as an oxidation-reduction (redox) reaction.
