Question

Дано: m(F2)=7,8г F2+NaCl V(Cl2)=? СРОЧНООО РЕШЕНИЕ

Answer 1

Решение:

7,8г...................................х
F2 + 2NaCl = 2NaF + Cl2 
38 г.................................22,4

Ar (F2) = 38г

7,8г-----хл
38г-----22,4л

х = (7,8×22,4)/38 = 4,6 л

Ответ: V(Cl2) = 4,6 л

Answer 2

Balancing Chemical Equation

To solve the given chemical equation, we need to balance it. The equation provided is:

m(F2) = 7.8g + F2 + NaCl + V(Cl2) = ?

First, let's balance the chemical equation to determine the products formed.

Balancing the Equation

The given equation seems to be incomplete, but we can still balance it based on the information provided. Balancing chemical equations involves ensuring that there are an equal number of each type of atom on both sides of the equation.

Balancing Steps

1. Start by balancing the non-hydrogen and non-oxygen atoms. In this case, we have F, Na, and Cl. 2. Then, balance the hydrogen and oxygen atoms if they are present in the equation.

Solution

Based on the given equation, it seems to be incomplete, and it's not clear what the products of the reaction are. However, if we assume that the reaction involves the formation of NaF and NaCl, the balanced equation would be:

2NaCl + F2 → 2NaF + Cl2

In this balanced equation, 2 moles of NaCl react with 1 mole of F2 to produce 2 moles of NaF and 1 mole of Cl2.

Calculation

Given: m(F2) = 7.8g

To find the volume of Cl2 produced, we need to know the molar mass of F2 and the stoichiometry of the reaction. Without this information, it's not possible to calculate the volume of Cl2 produced.

If you have additional information about the reaction or the products formed, please provide it so that we can accurately calculate the volume of Cl2 produced.
