Answer:

C) salt

Explanation:

  • Water is a very important component of life forms and is thus an essential factor for the individual as it is an important  factor that stretches further, as it tends to absorb the heat and give out the cooling effects.  
  • The more or high density of water is characterized by the presence of sea salts and thus the amount of freshness in water is dependent on their amount of salt concentration, the layer that represents this is called as halocline and this plays a big role in the regulating the temperature of the oceanic waters.
  • Warm water bodies are known to have a high amount of salt contents and thus dryness is generally associated with the topics as compared to cool and dense water of the polar areas.

Choose the statement below that is TRUE.
Leni [432]

Answer: Option (a) is the correct answer.

Explanation:

A weak acid is defined as an acid that dissociates partially when dissolve in water or a polar solvent.

For example, acetic acid is a weak acid and when dissolved in water it dissociates partly into ions as follows.

         CH_{3}COOH(aq) \rightleftharpoons CH_{3}COO^{-}(aq) + H^{+}(aq)

And, a strong acid is defined as an acid which when dissolved in water dissociates completely into ions.

For example, HCl is a strong acid and when dissolved in water it dissociates completely.

       HCl \rightarrow H^{+} + Cl^{-}

Thus, we can conclude that the statement a weak acid solution consists of mostly non-ionized acid molecules, is true.

Consider the reaction: A (aq) ⇌ B (aq) at 253 K where the initial concentration of A = 1.00 M and the initial concentration of B
Ugo [173]

Answer:

The maximum amount of work that can be done by this system is -2.71 kJ/mol

Explanation:

Maximum amount of work denoted change in gibbs free energy (\Delta G) during the reaction.

Equilibrium concentration of B = 0.357 M

So equilibrium concentration of A = (1-0.357) M = 0.643 M

So equilibrium constant at 253 K, K_{eq}= \frac{[B]}{[A]}

[A] and [B] represent equilibrium concentrations

K_{eq}=\frac{0.357}{0.643}=0.555

When concentration of A = 0.867 M then B = (1-0.867) M = 0.133 M

So reaction quotient at this situation, Q=\frac{0.133}{0.867}=0.153

We know,  \Delta G=RTln(\frac{Q}{K_{eq}})

where R is gas constant and T is temperature in kelvin

Here R is 8.314 J/(mol.K), T is 253 K, Q is 0.153 and K_{eq} is 0.555

So, \Delta G=8.314\times 253\times ln(\frac{0.153}{0.555})mol/K

                           = -2710 J/mol

                            = -2.71 kJ/mol

The air inside a flexible 3.5L container has a pressure of 115Kpa. What should the volume of the container be increased to in th
LenaWriter [7]

Answer:

V₂ = 4.82 L

Explanation:

Given data:

Initial volume of gas = 3.5 L

Initial pressure = 115 Kpa

Final volume = ?

Final Pressure = 625 torr

Solution:

Final Pressure = 625 torr (625/760 =0.82 atm)

Initial pressure = 115 Kpa (115/101 = 1.13 atm)

The given problem will be solved through the Boly's law,

"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"

Mathematical expression:

P₁V₁ = P₂V₂

P₁ = Initial pressure

V₁ = initial volume

P₂ = final pressure

V₂ = final volume  

Now we will put the values in formula,

P₁V₁ = P₂V₂

1.13 atm × 3.5 L = 0.82 atm × V₂

V₂ = 3.955 atm. L/0.82 atm

V₂ = 4.82 L
