A gas that was cooled to 200 Kelvin has a volume of 65.8 L. If its initial volume was 132.4 L, what was its initial temperature?

Answers

Answer:

Initial temperature, T1 = 99.4 Kelvin

Explanation:

Given the following data;

Initial volume, V1 = 65.8 LitresFinal temperature, T2 = 200 KelvinFinal volume, V2 = 132.4 Litres

To find the initial temperature (T1), we would use Charles' law;

Charles states that when the pressure of an ideal gas is kept constant, the volume of the gas is directly proportional to the absolute temperature of the gas.

Mathematically, Charles' law is given by the formula;

[tex] \frac {V}{T} = K [/tex]

[tex] \frac {V_{1}}{T_{1}} = \frac {V_{2}}{T_{2}} [/tex]

Making T1 as the subject formula, we have;

[tex] T_{1} = \frac {V_{1}T_{2}}{V_{2}} [/tex]

Substituting the values into the formula, we have;

[tex] T_{1} = \frac {65.8 * 200}{132.4} [/tex]

[tex] T_{1} = \frac {13160}{132.4} [/tex]

Initial temperature, T1 = 99.4 Kelvin

How many moles of KClO3 must decompose in order to produce 9 moles of oxygen gas (O2) using the following reaction by completing the t-chart below.

Answers

Answer: 6 moles of [tex]KClO_3[/tex] will be decomposed.

Explanation:

We are given:

Moles of oxygen gas produced = 9 moles

The chemical equation for the decomposition of [tex]KClO_3[/tex] follows:

[tex]2KClO_3\rightarrow 2KCl+3O_2[/tex]

By the stoichiometry of the reaction:

If 3 moles of oxygen gas is produced by 2 moles of [tex]KClO_3[/tex]

So, 9 moles of oxygen gas will be produced by = [tex]\frac{2}{3}\times 9=6mol[/tex] of [tex]KClO_3[/tex]

Hence, 6 moles of [tex]KClO_3[/tex] will be decomposed.

Compare the reactivity of Sodium and Potassium when reacting with Chlorine.​

Answers

Explanation:

Both sodium and potassium belong to the same group. They both have only one electon in their outermost shell. But they belong to different periods. Sodium has 3 shells while potassium has 5. As the distance between the valence electron and the nucleus is more in potassium. It experience lesser pull by the nucleus and so can give away the valence electron very easily as compared to sodium which experience a greater pull from the nucleus. Thus potassium is more reactive. Reactivity increases on moving down the group.

Answer:

Sodium and potassium belongs to same group . Both has 1 electron to donate but sodium is less reactive because nuclear attraction makes it little bit difficult to loose electron as compared to potassium in which nuclear attraction becomes unable to pull the electrons towards itself . Hence we easily remove electron moreover due to screening effect also takes place .

Ricardo compra un gaseosa en el súper al destaparla la gaseosa comienza a salir espuma y vuelca la mitad al piso ¿Por qué puede ocurrir eso?

Answers

Answer:

Las bebidas gaseosas como las gaseosas están hechas de un soluto de dióxido de carbono gaseoso en un líquido. La solubilidad del dióxido de carbono en el líquido depende de la presión y la temperatura de la lata de refresco, y también de agitar la lata de refresco que introduce burbujas que permanecen ocultas hasta que se abre la lata antes de que burbujee.

Por lo tanto, dado que la presión en la lata de refresco permanece constante, elevar la temperatura, agitar la lata de refresco o congelar el refresco, lo que aumenta la cantidad de dióxido de carbono en la porción líquida, hará que el refresco forme espuma y se derrame.

2. Nitric oxide contains 46.66% nitrogen and 53.34% oxygen. Water contains 11.21% hydrogen and 88.79% oxygen. Ammonia contains 17.78% hydroger and 82.22% nitrogen. Use these data to verify the law of reciprocal proportions. ​

Answers

Answer:

The law of reciprocal proportions states that if two elements react individually with a given weight of a third element, the ratio of the masses with which they combine with the third element are either the same or a simple multiple of the ratio of the masses with which they combine with each other

The compounds formed includes;

1) Nitric oxide, NO

Nitrogen = 46.66% × 30.01 = 14

Oxygen = 53.34% × 30.01 = 16

2) Water, H₂O

Hydrogen = 11.21% × 18.01528 = 2

Oxygen = 88.79% × 18.01528 ≈ 16

3) Ammonia, NH₃

Hydrogen = 17.78% × 17.031 ≈ 3

Nitrogen = 82.22% × 17.031 ≈ 14

The ratio of nitrogen to oxygen in nitric oxide = 14:16 = 7:8

The ratio of nitrogen to hydrogen in ammonia = 14:3

The ratio in which hydrogen and oxygen combine with nitrogen = 3/16

The ratio of hydrogen and oxygen combine with each other in water = 2/16

Therefore, the ratio with which hydrogen and oxygen combine with nitrogen, is (2/3) times the ratio with which they combine with each other, which verifies the law of reciprocal proportions

Putting rock salt on the roads during a snowstorm is an example of: A. Boiling point elevation B. Vapor pressure raising C. Vapor pressure lowering D. Freezing point depression

Answers

Answer:

The correct answer is - D. Freezing point depression.

Explanation:

When rock salt is spread over snow-covered icy roads, it generates a liquid layer over it by melting from the surface thereby lowering or depression in the freezing point below the ice.

Therefore, due to this liquid layer comes into the contact with the ice present on the road and causes other ice to melts. This keeps on decreasing the volume of the ice on the road therefore, rock salts spread on the roads during a snowstorm.

What is the name of N2C14? Explain how you determined the bond type and the steps you used to determine the naming convention for the compound.

Answers

Answer:

One way to predict the type of bond that forms between two elements is to compare the electronegativities of the elements. In general, large differences in electronegativity result in ionic bonds, while smaller differences result in covalent bonds. the bonding is covalent bcz its between the most electronegative atom nitrogen and carbon .

Since the electronegativity difference between nitrogen and chlorine is not very much so chemical bonding is the only bond between them Thus the name of  N2C14 is Dinitrogen Tetrachloride and there is covalent bonding in this compound

What is chemical bonding?

There are two types of bonding in chemistry, one is ionic bonding while other is covalent bonding. Ionic bonding is due to the complete transfer of electron from one  element to other. While the covalent bond is due to the equal sharing of electron by each element

Metals and non metals combine to form ionic bond while the element with the same electronegativity form covalent bonding.

To name this we have to see the number of element and accordingly use di, tri and the write the name of first element and then second element's name with ide

Thus the name of  N2C14 is Dinitrogen Tetrachloride and there is covalent bonding in this compound

Consider the reaction. 2HF(g)—H2(g)+F2(g). What is the value of Keq for the reaction expressed in scientific notation

Answers

Answer:

A). 2.1 × [tex]10^{-2}[/tex]

Explanation:

Given reaction,

2[tex]HF[/tex] (g) ⇄ [tex]H_{2}[/tex] (g) + [tex]F_{2}[/tex] (g)

The concentrations are as following;

[tex]HF[/tex] = 5.82 × [tex]10^{-2}[/tex] M

[tex]H_{2}[/tex] = 8.4 × [tex]10^{-3}[/tex] M

[tex]F_{2}[/tex] = 8.4 × [tex]10^{-3}[/tex] M

So,

[tex]K_{eq}[/tex] = [([tex]H_{2}[/tex] ) × ([tex]F_{2}[/tex])] ÷ [[tex]HF[/tex]]^2

Now,

We can determine the value of [tex]K_{eq}[/tex] by substituting the values in above formula:

[tex]K_{eq}[/tex] = [ (8.4 × [tex]10^{-3}[/tex] M) × (8.4 × [tex]10^{-3}[/tex] M)] ÷ [(5.82 × [tex]10^{-2}[/tex])^2

= 2.08 * [tex]10^{-2}[/tex]

=  2.1 × [tex]10^{-2}[/tex]

[tex]K_{eq}[/tex] = 2.1 × [tex]10^{-2}[/tex]

Thus, option A is the correct answer.

A gas at 100 Celsius has a volume of 33.5 L. What is its new volume after it is cooled to 25 Celsius?

Answers

Answer:

[tex]\boxed {\boxed {\sf 8.38 \ L}}[/tex]

Explanation:

We are asked to find the new volume of a gas after a change in temperature. We will use Charles's Law, which states the volume of a gas is directly proportional to the temperature. The formula for this law is:

[tex]\frac {V_1}{T_1}= \frac{V_2}{T_2}[/tex]

The gas starts at 100 degrees Celsius and a volume of 33.5 liters. Substitute these values into the formula.

[tex]\frac {33.5 \ L}{100 \textdegree C}=\frac{ V_2}{T_2}[/tex]

The gas is cooled to 25 degrees Celsius, but the volume is unknown.

[tex]\frac {33.5 \ L}{100 \textdegree C}=\frac{ V_2}{25 \textdegree C}[/tex]

We want to find the volume of the gas after it is cooled.  We must isolate the variable V₂. It is being divided by 25 degrees Celsius and the inverse of division is multiplication. Multiply both sides of the equation by 25 °C.

[tex]25 \textdegree C*\frac {33.5 \ L}{100 \textdegree C}=\frac{ V_2}{25 \textdegree C}* 25 \textdegree C[/tex]

[tex]25 \textdegree C*\frac {33.5 \ L}{100 \textdegree C}= V_2[/tex]

The units of degrees Celsius cancel.

[tex]25*\frac {33.5 \ L}{100 }= V_2[/tex]

[tex]8.375 \ L = V_2[/tex]

The original measurements have 3 significant figures, so our answer must have the same. For the number we found, that is the hundredth place. The 5 in the thousandths place tells us to round the 7 up to an 8.

[tex]8.38 \ L \approx V_2[/tex]

The new volume after the gas is cooled is approximately 8.38 liters.
