Answer:

183.22mL

Explanation:

Using Charles law equation, which is as follows:

V1/T1 = V2/T2

Where;

V1 = initial volume (mL)

T1 = initial temperature (K)

V2 = final volume (mL)

T2 = final temperature (K)

Note that standard temperature of a gas is 273K.

Hence, based on the provided information, V1 = 500.0mL, T1 = 745K, V2 = ?, T2 = 273K

Using the formula; V1/T1 = V2/T2

500/745 = V2/273

Cross multiply

V2 × 745 = 500 × 273

745V2 = 136500

V2 = 136500/745

V2 = 183.22

At standard temperature (273K), the new volume will be 183.22mL.

Answer:

D: fussion

Explanation:

The process called nuclear fussion.

for example, four hydrogen atoms combine in a nuclear fussion reaction to form one helium atom.

Answer:

I believe it's D. I searched up a lethal table chart and it states Aspirin is even more toxic than chlorine. As for the other two, it didn't specifically state it was toxic with one dose - meaning you have to take more than one dose for toxicity to take effect.

The special cases of gas laws and its description includes:

A. Boyle's law: P1 V1 = P2 V2

B. Charles's law: V/T = k or V1 / T1 = V2 / T2

C. Avogadro's law: V = kn

D. Dalton's law: Ptotal = P1 + P2 + P3 + .

Gas laws are laws that relate a gas's pressure, volume, and temperature. Boyle's law, named after Robert Boyle, states that the pressure P of a gas varies inversely with its volume V at constant temperature, or PV = k, where k is a constant. Charles' law is named after J. -A. -C.

They also include; Gay-Lussac's Law, Avogadro's Law and Dalton's law of partial pressures.

Answer:

I think it should be about maybe the times of the dinosaurs

also I think 23 to 16 billion years

Explanation:

No explanation sorry if im wrong

Mammals are the animals of the vertebrate group with the presence of the mammary gland. About 16-23 billion years ago hooved animals lived before humans.

Hoofed animals or mammals the even and odd-toed ungulates that have toes in their feet region used to balance their body weight. They have a nail-like case known as a hoof.

Hoofs protect the feet area and enable fast running in mammals. Some examples of hoofed mammals are a cow, zebra, antelope, moose, horse, deer, etc.

Therefore, humans evolved in the Oligocene Epoch and the mammals in the Cretaceous or the Jurassic period.

Answer: The enthalpy change for this reaction is, -803 kJ

Explanation:

The balanced chemical reaction is,

[tex]CH_4(g)+2O_2(g)\rightarrow CO_2(g)+2H_2O(g)[/tex]

The expression for enthalpy change is,

[tex]\Delta H=\sum [n\times \Delta H_f(product)]-\sum [n\times \Delta H_f(reactant)][/tex]

[tex]\Delta H=[(n_{CO_2}\times \Delta H_{CO_2})+(n_{H_2O}\times \Delta H_{H_2O})]-[(n_{O_2}\times \Delta H_{O_2})+(n_{CH_4}\times \Delta H_{CH_4})][/tex]

where,

n = number of moles  

Now put all the given values in this expression, we get

[tex]\Delta H=[(1\times -394)+(2\times -242]-[(2\times 0)+(1\times -75)][/tex]

[tex]\Delta H=-803kJ[/tex]

Therefore, the enthalpy change for combustion of methane is, -803 kJ

Answer:

0.914moles

Explanation:

The number of moles in a substance can be got by dividing the number of atoms/molecules/particles by Avagadro's constant (6.02 × 10^23).

That is;

number of moles (n) = number of atom (nA) ÷ 6.02 × 10^23

According to this question, there are 5.5 x 10-23 molecules of H2O

n = 5.5 x 10^23 ÷ 6.02 × 10^23

n = 0.914 × 10^(23-23)

n = 0.914 × 10^0

n = 0.914 × 1

n = 0.914moles

Answer:

See explanation below

Explanation:

In order to do this, you are missing two important data, which are the initial temperatures of the water and the rod.

For practical purposes, I will assume this data, and then you'll just replace the procedure with your data to get an accurate result.

So, for this exercise, I will assume that the rod of Chromiun was heat to 100 °C and then cooled with water at 20 °C, so the final temperature is 54.5 °C.

To get the specific heat, we need to use the following expression:

q = m.C.ΔT  (1)

Where:

q: Heat of the substance/compound

m: mass

C: specific heat

ΔT: Difference of temperature of the mixture.

With this expression, we need to calculate first the heat of the water, because:

q₁  + q₂ = 0

Therefore, with the value of the transfered heat, we can determine later the specific heat. So, As we have the specific heat of water which is 4.18 J/g °C, and the temperature and mass, we can determine the heat of the mixture:

ΔT = 54.5 - 20 = 34.5 °C

q₁ = 35 * 4.18 * 34.5

q₁ = 5047.35 J

Now, we can determine the specific heat of the rod:

q₁ = -q₂

-5047.35 = 323.98 * (54.5 - 100) * C

-5047.35 = -14741.09C

Hope this helps

Heat is the energy that a thing possesses as a result of the movement of its atoms and molecules, which are always bouncing off of one another and other objects. An object's atoms and molecules move more quickly when we add energy to it, which increases the object's energy of motion or heat.

The gas will travel more quickly in the container if the temperature is raised. This occurs as a result of the particles' increased kinetic energy caused by heating. There will be more collisions between particles if they are traveling faster.

A substance's atoms and molecules move more quickly when it is heated. Whether the substance is a solid, liquid, or gas, this occurs.

Answer:

If it can change shapes easily.

Explanation:

A fixed volume eliminates gas as a possible state of matter, therefore leaving liquid and solid.

If the substance can easily change shape, it is a liquid. If it cannot change shape, then it is a solid.

Another way to determine the state of matter is through particle movement.

If particles slip past each other, it is a liquid. If particles vibrate in place, it is a solid.
