Answer:

Ionic compounds generally form between elements that are metals and elements that are nonmetals. For example, the metal calcium (Ca) and the nonmetal chlorine (Cl) form the ionic compound calcium chloride (CaCl2). In this compound, there are two negative chloride ions for each positive calcium ion.

A mixture of 0.600 mol of bromine and 1.600 mol of iodine is placed into a rigid 1.000-L container at 350°C.
nata0808 [166]

The equilibrium constant for this reaction at 350°C is determined as 5.85.

<h3>Concentration of each component</h3>

concentration of bromine, C(Br) = 0.6 mol/1 = 0.6

concentration of iodine, C(I) = 1.6 mol/1 = 1.6

<h3>Create an ICE table</h3><h3>What is ICE table?</h3>

An ICE table is a tabular system of keeping track of changing concentrations in an equilibrium reaction.

ICE is an abbreviation that stands for initial, change, equilibrium.

Create ICE table for the reactants and products formed;

      Br2(g)   +     I2(g)    ↔     2IBr(g)

I     0.6              1.6                 0

C    -1.19            -1.19               1.19

E    0.6 - 1.19      1.6  - 1.19       1.19

E = -0.59           0.41                1.19

<h3>Equilibrium constant </h3>

The equilibrium constant is calculated as follows;

KC = [IBr]²/[Br][I]

KC = (1.19²) / (0.59 x 0.41)

KC = 5.85

Thus, the equilibrium constant for this reaction at 350°C is determined as 5.85.

Speeds up the reaction but does not change k
notka56 [123]
The answer is catalyst.

A catalyst is characterized by acceleration the rate of a chemical reaction but not modifiy the equilibrium, which is what k represents (the constant of equilibrium of the reaction).

The catalyst manages that the reaction goes through a different pathway, with a lower activation energy, so the transition compound is reached faster and the whole reaction goes faster, but the final species and their equilibriium concentrations do not change.

Vinegar contains 5g of acetic in 100mL of solution so the (w/v)% concentration is:
Andreyy89

The (w/v)% concentration of vinegar contains 5g of acetic in 100mL of solution is approx 0.5 %

<h3>What is Concentration ?</h3>

The concentration of a chemical substance expresses the amount of a substance present in a mixture.

There are many different ways to express concentration.(w/v)% is one of them.

Given ;

  • Mass of solute(acetic acid) is 5.0 g
  • Volume of solution is 100.0 mL.

We need to convert the grams of acetic acid to moles ;

Formula of acetic acid is CH₃COOH

Thus,

Molar mass of acetic acid = 2(12.01) + 4(1.01) + 2(16)  

                                           = 24.02 + 4.04 + 32

                                           = 60.06 grams per mol

Moles of acetic acid = 5.0/60.06

                                 

                                 = 0.083 moles

(w/v)% = 0.083 x 60 / 1000 x 100

          = 0.498 %

          = 0.5 %

Hence, The (w/v)% concentration of vinegar contains 5g of acetic in 100mL of solution is approx 0.5 %
