Answer;

-Macroscopic properties remain constant

-Concentrations remain constant

-No change to copper solution seen;

-Rate of reverse/backwards reaction = rate of forward reaction;

Explanation;

In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time, so that there is no observable change in the properties of the system.

-It is a a condition in the course of a reversible chemical reaction in which no net change in the amounts of reactants and products occurs. A reversible chemical reaction is one in which the products, as soon as they are formed, react to produce the original reactants.

What is the electronegativity difference between oxygen and fluorine? What type of bond is this?
JulijaS [17]

Answer:

Veja, por exemplo, que os elementos mais eletronegativos são os que estão no canto superior direito da tabela, isto é, o flúor (4,0) e o oxigênio (3,5), e os menos eletronegativos são os que estão no canto inferior esquerdo, que são o frâncio (0,8) e o césio (0,8).

How many grams of water contain 2.50 x 10^24 atoms of hydrogen?
Mama L [17]

The mass of water that contains 2.5×10²⁴ atoms of Hydrogen is 74.79 g

<h3>Avogadro's hypothesis </h3>

From Avogadro's hypothesis,

6.02×10²³ atoms = 2 g of H

Therefore,

2.5×10²⁴ atoms = (2.5×10²⁴ × 2) / 6.02×10²³

2.5×10²⁴ atoms = 8.31 g of H

<h3>How to determine the mass of water </h3>
  • 1 mole of water H₂O = (2×1) + 16 = 18 g
  • Mass of H in 1 mole of water = 2 g

2 g of H is present in 18 g of water.

Therefore,

8.31 g of H will be present in = (8.31 × 18) / 2 = 74.79 g of water.

Thus, 2.5×10²⁴ atoms of Hydrogen is present in 74.79 g of water.

A certain compound of bromine and fluorine is used to make UF6, which is an important chemical in the processing and reprocessin
Aleksandr [31]

Answer: The empirical formula is BrF_3

Explanation:

If percentage are given then we are taking total mass is 100 grams.

So, the mass of each element is equal to the percentage given.

Mass of Br=  58.37 g

Mass of F = (100-58.37) = 41.63 g

Step 1 : convert given masses into moles.

Moles of Br=\frac{\text{ given mass of Br}}{\text{ molar mass of Br}}= \frac{58.37g}{80g/mole}=0.73moles

Moles of F =\frac{\text{ given mass of H}}{\text{ molar mass of H}}= \frac{41.63g}{19g/mole}=2.2moles

Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.

For Br = \frac{0.73}{0.73}=1

For F = \frac{2.2}{0.7}=3

The ratio of Br: F= 1 : 3

Hence the empirical formula is BrF_3
