Which of the following statements describe a system at equilibrium? There may be multiple correct answers. Select all that apply

. Group of answer choices The rate of the forward reaction has decreased to zero. The concentrations of reactants and products are all equal to 1 M. The rate of the forward reaction and the rate of the reverse reaction are equal. The concentrations of the products are equal to the concentrations of the reactants. The concentrations of the reactants and products no longer change.

Answer:

The rate of the forward reaction and the rate of the reverse reaction are equal

The concentrations of the reactants and products no longer change.

Explanation:

The equilibrium state is a state of rest or motion of chemical system.

These are some of the condition for dynamic equilibrium of a system:

the systems must be involved in reversible chemical reactions.

the rate of forward reaction is equal to that of the reverse process.

the system offers no resistance to any change in any of the factors.

there is no change in concentration of each of the species in equilibrium with respect to time.

We can see that a system in equilibrium clearly identifies with the chosen options.

Answer:

293 grams Fe₂S₃(s)

Explanation:

16Fe(s)  +     3S₈(s)     =>     8Fe₂S₃(s)

Excess  |   1.25 mole    |         ? grams

moles Fe₂S₈ produced = 8/3(1.25) mole Fe₂S₃(s) Yield = 3.33 mole  Fe₂S₃(s)

∴ grams of  Fe₂S₈ = 3.33 mole x 88 g/mole = 293 grams Fe₂S₃(s)

Calculate the pH of a buffer that is 0.13 M in lactic acid and 0.11 M in sodium lactate
Gelneren [198K]
Acidity of lactic acid = pKa = 3.85
Ca = 0.13M
Cs = 0.11M
<span>Henderson-Hasselbalch equation:</span>
pH = pKa + log(Cs/Ca)
pH = 3.85 + log(0.11M/0.13M) = 3.85 + log0,846 = 3.85 - 0.073 = <u>3.777</u>

Element z reacts with bromine to form an ionic compound zbr2
slamgirl [31]

Explanation:

<u>Physical properties of ZBr₂</u>

The compound is an ionic substance. Therefore it will have properties of ionic compounds. Some of these properties are:

  • it is a hard solid usually with high melting points or a liquid with high boiling points.
  • Soluble in water and insoluble in non-polar solvents.
  • It can conduct electricity in aqueous solutions or in molten form.
  • it will undergo a fast reaction.

<u>Z is a metal</u>

To form ionic compound, a metal will combine with a non-metal. Bromine is a non-metal and it is expected that Z will be a metal. This is because ionic bonds involves transfer of electron from one specie to the other. Metals are usually the donor and non-metals are the receptor. This is how ionic bond forms. The electrostatic attraction resulting from the ions produced the ionic bond.

<u>Formula of the oxide</u>

ZO

                 Z                           0

                +2                         -2

It is obvious that Z has 2 valence electrons. It will lose the two valence electrons to attain stability.

Oxygen requires 2 electrons to resemble Neon. This combination will give a compound ZO.
