In the diagram, what is happening to the ENERGY during Segment C? Phase Change Diagram_Water Question 16 options: The kinetic en

ergy is increasing because the molecules are speeding up. The potential energy is decreasing as the molecules break apart from each other. The potential energy is increasing because the heat is being used to break the connections between the molecules. The kinetic energy is decreasing because the molecules are slowing down.

There was an increase in kinetic energy during the segment C and in other segments

Recall: That temperature is a measure of the average kinetic energy, so increasing temperature all cause increasing kinetic energy and vice versa.

However too, the heat energy which is added during the phase change is usually used to overcome forces in order to hold the molecules together.

<h3>What is kinetic energy?</h3>

Kinetic energy is the type of energy an object or a body posesss due to it motion

The body usually maintains it's kinetic energy unless the speed changes

<h3>What it potential energy?</h3>

Potential energy is a type of energy an object or a body had due to its relative position.

Does wasting water also waste energy? Explain your reasoning.
77julia77 [94]

Answer:

Yes.

Explanation:

Wasting household water does not ultimately remove that water from the global water cycle, but it does remove it from the portion of the water cycle that is readily accessible and usable by humans. Also, "wasting" water wastes the energy and resources that were used to process and deliver the water.

yulyashka [42]

The element cesium forms a  positive ion with the charge +1 . The symbol for this ion is Ce⁺, and the name is cesium ion. The number of electrons in this ion is 54.

<h3>What group does the element cesium belong to in the periodic table?</h3>

Cesium belong to the Group 1A of the periodic table.

Group 1A elements are known as alkali metals.

The alkali metals react with water to form alkalis. They form ions with a positive charge of +1 by the loss of an electron.

In conclusion, cesium is an alkali metals it belongs to group 1A of the periodic table. It forms a positive ion with a charge of +1 by the loss of an electron.

Calculate the amount of CO2 (in kg) released when 1 kg of coal is burned. Assume that carbon content of the coal is 50% by mass.
Delvig [45]

Answer:

1.8321 kg

Explanation:

The given 1 kg of coal contains 50% of the carbon atom by mass. Thus, mass of carbon in coal is \frac {50}{100}\times 1\ kg=0.5\ kg

Also, 1 kg = 1000 g

So, mass of carbon = 500 g

The formula for the calculation of moles is shown below:

moles = \frac{Mass\ taken}{Molar\ mass}

Molar mass of carbon = 12.0107 g/mol

Moles of methanol = 500 g / 12.0107 g/mol = 41.6295 moles

Considering the reaction:

C+O_2\rightarrow CO_2

From the reaction,

1 mole of C react to form 1 mole of CO_2

So,

41.6295 moles of C react to form 41.6295 moles of CO_2

Moles of CO_2 = 41.6295 moles

Molar mass of CO_2 = 44.01 g/mol

So, Mass = Moles × Molar mass = 41.6295 moles × 44.01 g/mol = 1832.1143 g

Also, 1g = 0.001 kg

<u>So, amount of CO_2 released = 1.8321 kg</u>

Which statements are true? The oxidation number for Cu(s) is +2. An oxidizing agent gains electrons. Na+ is formed from the redu
just olya [345]

<u>Answer:</u> The correct statements are:

An oxidizing agent gains electrons and Zn^{2+} is formed from the oxidation of Zn(s).

<u>Explanation:</u>

For the given options:

  • <u>Statement 1</u>: The oxidation number for Cu(s) is +2

Copper is the 29th element of the periodic table having electronic configuration of [Ar]3d^{10}4s^1

This element can show +1 or +2 oxidation states. Thus, this statement is false.

  • <u>Statement 2:</u> An oxidizing agent gains electrons.

Oxidizing agents are defined as the agents which oxidize other substance and itself gets reduced. These agents undergoes reduction reactions and reduction reaction is the reaction in which an atom gains electrons.

Thus, this statement is True.

  • <u>Statement 3:</u>  Na^+ is formed from the reduction of Na(s)

Oxidation reaction is defined as the reaction in which an atom looses its electrons. Here, oxidation state of the atom increases.

X\rightarrow X^{n+}+ne^-

Sodium is the 11th element and it will loose electrons to form sodium ion.

Na\rightarrow Na^++e^-

Hence, this statement is false.

  • <u>Statement 4:</u> The oxidation number for Hg(l) is 0.

Mercury is the 80th element of the periodic tale having electronic configuration of [Xe]4f^{14}5d^{10}6s^2

This element can show +1 or +2 oxidation states. Thus, this statement is false.

  • <u>Statement 5:</u> A reducing agent gains electrons.

Reducing agents are defined as the agents which reduces the other substance and itself gets oxidized. These agents undergoes oxidation reactions and oxidation reaction is defined as the reaction in which an atom looses its electrons.

Thus, this statement is false.

  • <u>Statement 6:</u>  Zn^{2+} is formed from the oxidation of Zn(s)

Oxidation reaction is defined as the reaction in which an atom looses its electrons. Here, oxidation state of the atom increases.

X\rightarrow X^{n+}+ne^-

Zinc is the 30th element and it will loose electrons to form zinc ion.

Zn\rightarrow Zn^{2+}+2e^-

Thus, this statement is True.

Hence, the correct statements are:

An oxidizing agent gains electrons and Zn^{2+} is formed from the oxidation of Zn(s).
