Answer:

Explanation:

The term change of phase means the same thing as the term change of state. ... i.e. during phase change, the energy supplied is used only to separate the molecules ; no part of it is used to increase the kinetic energy of the molecules. So its temperature will not rise, since kinetic energy of molecules remains the same.

Answer:

Answer:

The reaction combines the sodium with the hydrogen and oxygen in water to form sodium hydroxide and hydrogen gas, and you get a lot of energy released as heat as well. This heat actually melts any remaining sodium that has not reacted yet, and ignites the hydrogen gas, so you get the bang and the flash.

Considering the definition of percentage by mass, the correct answer is option D. the percent composition of carbon dioxide is 6.6%

The percentage by mass expresses the concentration and indicates the amount of mass of solute present in 100 grams of solution.

In other words, the percentage by mass of a component of the solution is defined as the ratio of the mass of the solute to the mass of the solution, expressed as a percentage.

The percentage by mass is calculated as the mass of the solute divided by the mass of the solution, the result of which is multiplied by 100 to give a percentage. This is:

[tex]percentage by mass=\frac{mass of solute}{mass of solution} x100[/tex]

In this case, you know:

Replacing in the definition of percentage by mass:

[tex]percentage by mass=\frac{13.203 grams}{200 grams} x100[/tex]

Solving:

percentage by mass= 6.60 %

Finally, the correct answer is option D. the percent composition of carbon dioxide is 6.6%

Answer:

A: Add a substance to the wash that reduces the number of charges transferred.

Explanation:

The attraction between opposite charges make the clothes attract together. To reduce them Increase the temperature of the air in the dryer to weaken the electric forces. Hence, option A is correct.

An electric dryer is used to dry the clothes and hair or other substances using electric current. A substance can have both negative and positive charges. The opposite charges will attract together while the negative charges repel.

By exposing clothes to electric dryer it will gain electrons from the dryer and the positive poles of the clothes will attracts it. The electric current from the dryer will make clothes temporarily polarised.

If temperature increases, the intermolecular force of attraction decreases by making the kinetic energy of molecules raised. Therefore by increasing the temperature of air from the dryer the attraction can be reduced.

No. Q < Kc, so reaction will shift to the right.

Explanation:

Answer: Ionic bonds form only between metals and nonmetals. That's because metals “want” to give up electrons, and nonmetals “want” to gain electrons. It takes energy to remove valence electrons from an atom and form a positive ion. Energy is released when an atom gains valence electrons and forms a negative ion

Explanation:

The equation of the reaction is given as;

12C + 16 H2 --> 4 C3H8

a. Simplify the equation;

The coefficients are 12, 16 and 4.

4 is a common factor, so divide all through by 4.

12/4 = 3, 16/4 = 4, 4/4 = 1

The equation is given as;

3 C + 4 H2 -->  C3H8

b. If 21 moles of  C3H8 are formed, how many moles of C was needed.

From the reaction;

3 mol C atoms reacts to form 1 mol of  C3H8

x mol would react to form 21 moles of  C3H8

3 = 1

x = 21

x = 21  * 3

x = 63 moles

Answer: D. 1600 L

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.

To calculate the moles, we use the equation:

[tex]\text{Number of moles}=\frac{\text{Given volume}}{\text {Molar volume}}[/tex]

[tex]\text{Number of moles of nitrogen}==\frac{1000L}{22.4L}=44.6moles[/tex]

[tex]\text{Number of moles of hydrogen}==\frac{2400L}{22.4L}=107.1moles[/tex]

[tex]N_2(g)+3H_2(g)\rightarrow 2NH_3(g)[/tex]  

According to stoichiometry :

3 moles of [tex]H_2[/tex] require 1 mole of [tex]N_2[/tex]

Thus 107.1 moles of [tex]H_2[/tex] will require=[tex]\frac{1}{3}\times 107.1=35.7moles[/tex] of [tex]N_2[/tex]

Thus [tex]H_2[/tex] is the limiting reagent as it limits the formation of product and [tex]N_2[/tex] is the excess reagent.

As 3 moles of [tex]H_2[/tex] give = 2 moles of [tex]NH_3[/tex]

Thus 107.1 moles of [tex]H_2[/tex] give =[tex]\frac{2}{3}\times 107.1=71.4moles[/tex]  of [tex]NH_3[/tex]

Volume of [tex]NH_3=moles\times {\text {Molar volume}}=71.4moles\times 22.4L/mol=1600L[/tex]

Thus volume of ammonia produced is 1600 L

Answer:

Decomposition

Explanation:

This shows a compound splitting into two

By definition, PbSO₄ → PbSO₃ + O₂ is a decomposition reaction, because a single substance decomposes producing two different substances.

First, you have to know that in a decomposition reaction, a single substance decomposes, producing two or more different substances. That is, in this type of reaction, two or more substances are formed from a compound.

The atoms that make up a compound are separated to give the products according to the formula:

AB → A + B

This type of reaction can occur spontaneously or caused by certain external factors, such as heat, which promote the decomposition of the molecule into simpler substances.

In this case, it is possible to observe that PbSO₄ → PbSO₃ + O₂ is a decomposition reaction, because a single substance decomposes producing two different substances.

If all the particles in a material are made up of

several smaller particles, and every larger particle

is identical, is the material a pure substance or

not? Explain your reasoning.

A pure substance is something like a compound and element. This material made of several particles which seem to be two different particles, I believe, is a mixture. So, it is not a pure substance mixtures are made up of more than one particle while compounds (In a fixed ratio, the fusion of two or more than two atoms) and elements are made up of one molecule essentially.

The given material is not a pure substance as it is made up of several smaller particles and some larger particles that are identical.

A pure substance is defined as a substance that has fixed chemical composition throughout the substance. A pure substance are not necessarily have to be of single substance or compound.

The given material is not a pure substance because it is made up of several different small particles. The material is made up of both small particle and large particles and both the particle do not have similar composition.

A pure substance is a homogeneous mixture. These substance has similar composition throughout the substance size of the particle  does not matter.

Thus, it is not a pure substance as it is made up of several smaller particles and some larger particles that are identical.
