Two gas samples are stored in a container with a solid barrier separating the gases. Gas A is at 125 °C, and Gas B is at 80 °C.

What will occur when the solid barrier is removed?

The molecules of Gas A will collide and mix with Gas B molecules. Gas A and Gas B molecules will all speed up. The final temperature will be greater than 125 °C.

The molecules of Gas A will collide and mix with Gas B molecules. Gas A molecules will slow down, and Gas B molecules will speed up. The final temperature will be between 80 °C and 125 °C.

The molecules of Gas A will collide but not mix with Gas B molecules. There will be no changes in the temperature of either side of the container.

Which statement is true about the rotational period of the moon?

Answers

less than the revolution perilous around earth

The statement is true  about the rotational period of the moon " the rotational period of the moon is equal to the revolution period around Earth."

What is rotational period?

A celestial object's rotation period may relate towards its sidereal rotation period, which is the time it takes for the object to complete one revolution around in its axis of rotation in sidereal seems like to the background stars.

What is revolution period?

The orbital period is also known as the revolution period. it takes for one astronomical object to complete one cycle around another. It refers to planets and asteroids orbiting the Sun, moons orbiting planets, planetary systems orbiting other stars, or double stars in astronomy.

What is moon?

In the night sky, the moon is just the brightest object. The moon doesn't at all produce its own light. It has no radiance. That is visible because the sun's light bounces off of it.

The rotational period of the moon is equal to the revolution period around Earth because the moon's rate of spin becomes tidally locked to its rate of revolution, it maintains the same face oriented towards the Earth In other words, every time the moon rounds the Earth, it rotates exactly once.

Therefore, the rotational period of the moon is equal to the revolution period around Earth will be correct answer.

a.
Covalent bond, ionic bond
c.
Van der waals force, dipole
b.
Electrostatic repulsion, strong nuclear force
d.
All of the above

Answers

Answer:

Electrostatic repulsion, strong nuclear force

Explanation:

The nucleus consists of protons and neutrons. protons are positively charged while neutrons possess no charge.

Since protons are positively charged, they repel each other strongly (like charges repel). This strong repulsion of like charges makes the nucleus somewhat unstable leading to spontaneous fission of heavy nuclei.

However, an opposing force called nuclear attractive force tends to hold the nucleons together. This attraction occurs when two nucleons are bonded by a particle called a π meson.

Hence, the two forces that act in the nucleus to create a  'nuclear tug-of-war' are electrostatic repulsion and a strong nuclear force.

How much heat do you need to raise the temperature of 300 g of ethanol from 0°C to 20°C?​

Answers

Answer:

14.6

Explanation:

I just took the test

The amount of heat to raise the temperature is 14.7J.

How do you calculate the heat needed to raise the temperature?

The specific heat capacity of a substance is the quantity of heat needed to raise the temperature of a unit quantity of the substance by one degree. Calling the amount of heat added Q, which will cause a change in temperature ∆T to a weight of substance W, at a specific heat of material Cp, then Q = w x Cp x ∆T

By applying the formula, we get

Q = w x Cp x ∆T

Q = 300 * 2.46 * 20/1000

Q = 14.760J

What is heat?

Heat is energy that is transferred from one body to another as the result of a difference in temperature.

When maganese dioxide is added to hydrogen chloride you get water maganese dichloride and chlorine gas write the balanved equation

Answers

Answer: When maganese dioxide is added to hydrogen chloride you get water maganese dichloride and chlorine gas then balanced equation is [tex]MnO_{2} + 4HCl \rightarrow 2H_{2}O + MnCl_{2} + Cl_{2}[/tex].

Explanation:

The word equation is given as maganese dioxide is added to hydrogen chloride you get water maganese dichloride and chlorine gas.

Now, in terms of chemical formulae this reaction equation will be as follows.

[tex]MnO_{2} + HCl \rightarrow H_{2}O + MnCl_{2} + Cl_{2}[/tex]

Here, number of atoms on reactant side are as follows.

Mn = 1O = 2H = 1Cl = 1

Number of atoms on product side are as follows.

Mn = 1O = 1H = 2Cl = 4

To balance this equation, multiply HCl by 4 on reactant side and multiply [tex]H_{2}O[/tex] by 2 on product side. Therefore, the equation can be rewritten as follows.

[tex]MnO_{2} + 4HCl \rightarrow 2H_{2}O + MnCl_{2} + Cl_{2}[/tex]

Hence, number of atoms on reactant side are as follows.

Mn = 1O = 2H = 4Cl = 4

Number of atoms on product side are as follows.

Mn = 1O = 2H = 4Cl = 4

Since, this equation contains same number of atoms on both reactant and product side. Therefore, this equation is now balanced equation.

Thus, we can conclude that when maganese dioxide is added to hydrogen chloride you get water maganese dichloride and chlorine gas then balanced equation is [tex]MnO_{2} + 4HCl \rightarrow 2H_{2}O + MnCl_{2} + Cl_{2}[/tex].

How many moles of hypomanganous acid. H3 MnO4, are contained in 22.912 g?

Answers

0.188mol

Explanation:

Using the formula;

mole = mass/molar mass

Molar mass of hypomanganous acid. (H3MnO4) = 1(3) + 55 + 16(4)

= 3 + 55 + 64

= 122g/mol

According to this question, there are 22.912g of H3MnO4

mole = 22.912g ÷ 122g/mol

A 25.0 L tank of nitrogen gas is at 25 oC and 2.05 atm . If the temperature stays at 25 oC and the volume is decreased to 14.5 L , what is the new pressure?

Answers

Answer:

[tex]\boxed {\boxed {\sf P_2 \approx 3.53 \ atm}}[/tex]

Explanation:

In this problem, the temperature stays constant. The volume and pressure change, so we use Boyle's Law. This states that the pressure of a gas is inversely proportional to the volume. The formula is:

[tex]P_1V_1=P_2V_2[/tex]

Now we can substitute any known values into the formula.

Originally, the gas has a volume of 25.0 liters and a pressure of 2.05 atmospheres.

[tex]25.0 \ L * 2.05 \ atm = P_2V_2[/tex]

The volume is decreased to 14.5 liters, but the pressure is unknown.

[tex]25.0 \ L * 2.05 \ atm = P_2 * 14.5 \ L[/tex]

Since we are solving for the new pressure, or P₂, we must isolate the variable. It is being multiplied by 14.5 liters and the inverse of multiplication is division. Divide both sides by 14.5 L .

[tex]\frac {25.0 \ L * 2.05 \ atm }{14.5 \ L}=\frac{P_2 *14.5 \ L}{14.5 \ L}[/tex]

[tex]\frac {25.0 \ L * 2.05 \ atm }{14.5 \ L}= P_2[/tex]

The units of liters cancel.

[tex]\frac {25.0 * 2.05 \ atm }{14.5 }=P_2[/tex]

[tex]\frac {50.25\ atm }{14.5 }=P_2[/tex]

[tex]3.53448276 \ atm = P_2[/tex]

The original values of volume and pressure have 3 significant figures, so our answer must have the same.

For the number we found, that is the hundredth place.

3.53448276

The 4 in the thousandth place (in bold above) tells us to leave the 3 in the hundredth place.

[tex]3.53 \ atm \approx P_2[/tex]

The new pressure is approximately 3.53 atmospheres.
