Choose the correct statement regarding the behavior of water.Group of answer choicesThe heat capacity of liquid water is greater
vodka [1.7K]

Answer:

The water phase with the smallest temperature increase when adding 10 kcal of heat is solid ice.

Explanation:

The rest of the statements are incorrect. The density of ice is lower than the density of water. The heat capacity of solid ice is greater almost twice the heat capacity of the liquid water. The heat capacity of vapors is less than heat capacity of liquid.

What are the substances making up a mixture called
dimulka [17.4K]

  • The substance that made up of a particular mixture can be regarded as Solute and solvent

  • A  mixture can be regarded as material which is made up of  more than one  different Chemical substance or substances , whereby they  are not chemically combined.

  • Substance could be any matter such as <em>salt, rice, and or compounds</em>

  • A mixture can be regarded as physical combination involving two or more substances whereby each entities identities are retained, then mixed in the form such as ;
  1. <em>solutions</em>
  2. <em> suspensions </em>
  3. <em> colloids</em>.

  • A mixture could be  in this form <em>(Solute + solvent = solution)</em>

Therefore, the substance that made up of a particular mixture can be regarded as <em>Solute and solvent</em>

What gets reduced in an electrolytic cell made with nickel and copper electrodes?
jekas [21]

Answer:

D. Ni²⁺  

Explanation:

We know at once that the answer cannot be A or C, because Ni and Cu are already in their lowest oxidation states.

The correct answer must be either B or D.

An electrolytic cell is the opposite of a galvanic cell. In the former, the reaction proceeds spontaneously. In the latter, you must force the reaction to occur.  

One strategy to solve this problem is:

  1. Look up the standard reduction potentials for the half reaction·
  2. Figure out the spontaneous direction.
  3. Write the equation in the reverse direction.

1. Standard reduction potentials

                                E°/V

Cu²⁺ + 2e⁻ ⟶ Cu; 0.3419

Ni²⁺ + 2e⁻ ⟶ Ni;  -0.257

2. Galvanic Cell

We reverse the direction of the more negative half cell and add.

                                       <u>E°/V </u>

Ni ⟶ Ni²⁺ + 2e⁻;           0.257

<u>Cu²⁺ + 2e⁻ ⟶ Cu;      </u>   0.3419

Ni + Cu²⁺ ⟶ Cu + Ni²⁺; 0.599

This is the spontaneous direction.

Cu²⁺ is reduced to Cu.

3. Electrochemical cell

                                        <u>E°/V</u>

Ni²⁺ + 2e⁻ ⟶ Ni;           -0.257

<u>Cu ⟶ Cu²⁺ + 2e⁻;        </u> <u>-0.3419</u>

Cu + Ni²⁺ ⟶ Ni + Cu²⁺; -0.599

This is the non-spontaneous direction.

Ni²⁺ is reduced to Ni in the electrolytic cell.

Are frosted flakes healthier than fruit loops?
Komok [63]

Answer:

The answer is below!!

Explanation:

Although Frosted Flakes are higher in sugar than other cereals and often not considered diet food, they can be part of a healthy weight-loss plan. Cereals that are low in calories and fat content such as Frosted Flakes may help you lose weight.

“Froot Loops is an excellent source of many essential vitamins and minerals and it is also a good source of fiber with only 12 grams of sugar,” said Celeste A. Clark, senior vice president of global nutrition for Kellogg's, which makes Froot Loops.

Hope I Helped!!
