Answer:

420.7 degrees C

Explanation:

Use the formula V1/T1 = V2/T2 (Charles' Law) to find T2. Make sure to convert  your temperatures to Kelvin by adding 273 to the Celsius temperature.

V1 = 4.50 L

V2 = 10 L

T1 = 39.2 C = 312.2 K

Solve V1/T1 = V2/T2 for T2 and you get T2 = V2T1/V1

T2 = (10 L)(312.2 K) / (4.50 L) = 693.8 K

You can subtract 273 to get the temperature back to Celsius.

T2 = 693.8 - 273 = 420.7 degrees C

Answer:

2CO + O2 =====> 2CO2          ΔH = -566 KJ

Explanation:

A thermochemical equation is a chemical equation that includes the enthalpy change of the reaction (Lumen Learning).

In a thermochemical equation, we can easily see the heat of reaction written after the symbols of reactants and products. It tells us whether heat was evolved or gained in the chemical process. When heat is gained ΔH = positive. When heat is evolved, ΔH = negative.

The thermochemical equation for the reaction of CO and O2 is shown below;

2CO(g) + O2(g) =====> 2CO2 (g)         ΔH = -566 KJ

Answer:

0.0153 mol

Explanation:

Mass of crucible and lid: 29.307 g

Mass of crucible, lid, and silver: 30.958 g

Number of moles = Mass /Molar mass

Mass of Silver = Mass of crucible, lid, and silver  -  Mass of crucible and lid

Mass of siilver = 30.958 g - 29.307 g

Mass of silver = 1.651 g

Molar mass of silver = 107.868 g/mol

Number of moles = 1.651 g / 107.868 g/mol

Number of moles = 0.0153 mol

Answer:

6.80×10¯²⁶ J

Explanation:

From the question given above, the following data were obtained:

Frequency (f) = 102.5 MHz

Energy (E) =?

Next, we shall convert 102.5 MHz to Hz. This can be obtained as follow:

1 MHz = 10⁶ Hz

Therefore,

102.5 MHz = 102.5 MHz × 10⁶ Hz / 1 MHz

102.5 MHz = 1.025×10⁸ Hz

Finally, we shall determine the energy. This can be obtained as follow:

Frequency (f) = 1.025×10⁸ Hz

Planck's constant (h) = 6.63×10¯³⁴ Js

Energy (E) =?

E = hf

E = 1.025×10⁸ × 6.63×10¯³⁴

E = 6.80×10¯²⁶ J

Answer:

In physics and chemistry, the law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed.

Explanation:

That is what I think on the subject

A law is more specific, such as this particular description of matter, whereas a theory can be more general and often includes more of a why. Atomic Theory explains why the law of conservation of matter exists; in chemical reactions, atoms simply rearrange and have the same mass before and after.

A theory is a well-thought-out elaboration for natural-world anecdotes that has been built using the methodological approach and incorporates many facts and hypotheses.

A scientific law, in overall, is a description of an observed phenomenon. It does not explain why or what causes the phenomenon.

A scientific theory is an explanation for a concept. It is a common misconception that with enough research, theories can become laws.

A law is more precise, such as this detailed definition of matter, whereas a theory is more general and frequently includes more of a why.

Atomic Theory explains why the law of conservation of matter exists; atoms simply rearrange and have the same mass before and after chemical reactions.

Thus, that's why, the law of conservation of mass law and not a theory.

Hello

Once in the Earth's atmosphere, clouds and the surface absorb the solar energy. The ground heats up and re-emits energy as longwave radiation in the form of infrared rays.

Explanation:

thanks

As the earth heats up, the atmosphere is warmed by long-wave infrared radiation. Thermal energy is released by the earth.

An atmosphere surrounding the earth and the place where all living and non-living things live together. The atmosphere keeps all objects safe and cover-up, and it also gives a covering from the outer rays and gases that can be harmful to biotic and abiotic factors.

The sun's rays come to the earth and increase the temperature of the earth, these rays reflect back to the atmosphere but are trapped, and this increase the warmth of the earth.

These rays are long wave infrared radiation and thermal energy is the energy that is heat energy and produces warmth

Thus, the atmosphere is warmed by long-wave infrared radiation.

Answer:

78.12 L

Explanation:

Given that,

Initial volume, V₁ = 105 L

Initial temperature, T₁ = 20°C = 20+273 = 293 K

New temperature, T₂ = -55 °C = 218 K

We need to find the new volume of the balloon. The relation between the volume and the temperature is given by :

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

Where

V₂ is the new volume

[tex]V_2=\dfrac{V_1T_2}{T_1}\\\\V_2=\dfrac{105\times 218}{293}\\\\V_2=78.12\ L[/tex]

So, the new volume is 78.12 L.

Balanced equation for Fe reacting with [tex]Cl_2[/tex]

[tex]2Fe + 3Cl_2[/tex] → [tex]2FeCl_3[/tex]

Iron filings are small shavings of ferromagnetic material.

When hydrochloric acid (HCl) reacts with iron filings (Fe) a dissolving metal reaction occurs with the Fe being converted to iron chloride ([tex]FeCl_2[/tex]) and hydrogen ([tex]H_2[/tex]).

The balanced equation is:

[tex]Fe + 2HCl[/tex] → [tex]FeCl_2 + H_2[/tex]

Note that reaction only produces [tex]FeCl_2[/tex] and not [tex]FeCl_3[/tex]. To make [tex]FeCl_3[/tex] you have to get more forcing and react Fe with chlorine gas ([tex]Cl_2[/tex]) at elevated temperature.

Since we are balancing equations here, below is the balanced equation for Fe reacting with [tex]Cl_2[/tex] (offered at no extra charge):
