Present in a state where it molecules are far apart during a change of state it's molecules slow down which change of state has most likely taken place from a gas to a liquid from a liquid to a gas from a solid to a liquid from a gas to a plasma

Answers

Answer:

The change of state that has occurred is from a gas to a liquid

Note: The question is incomplete. The complete question is given blow.

H₂O is initially present in a state where its molecules are far apart. During a change of state, its molecules slow down. Which change of state has most likely taken place?

from a gas to a liquid

from a liquid to a gas

from a solid to a liquid

from a gas to a plasma

Explanation:

Water can exists in three states: as gaseous water vapor, as liquid water, and as solid ice. Each of these states of water can be interconverted from one to another by the addition or removal of heat in a process known as change of state.

Liquid water can be converted to solid ice by the removal of heat, while solid ice ice can be converted to liquid water by the addition of heat. Also, liquid water can be converted to water vapor by the addition of heat, while water vapor can be converted to liquid water by the removal of heat.

Of the three states of water, the one in which the molecules are farthest apart is in the gaseous state. The molecules have high kinetic energy and move randomly while colliding with one another. When a heat is removed from these highly energetic molecules, the molecules slow down and lose some of their kinetic energy and a change of  occurs from gaseous to liquid state.

Therefore, the change of state that occurred as described, is from gas to liquid.

Antacid has a pH of 11. What does that tell you about its concentration of hydrogen ions? What does that tell you about its concentration of hydroxide ions?

Answers

Answer: The concentration of hydrogen ions is [tex]10^{-11}M[/tex] and the concentration of hydroxide ions is [tex]10^{-3}M[/tex]. Thus the concentration of hydroxide ions is more than the concentration of hydrogen ions.

Explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration.  

[tex]pH=-\log [H^+][/tex]

[tex]pOH=-\log[OH^-][/tex]

Putting in the values:

[tex]11=-\log[H^+][/tex]

[tex][H^+]=10^{-11}M[/tex]

[tex]pH+pOH=14[/tex]

[tex]pOH=14-11=3[/tex]

[tex]3=-log[OH^-][/tex]

[tex][OH^-]=10^{-3}M[/tex]

Thus the concentration of hydroxide ions is more than the concentration of hydrogen ions.

Many ski resorts and mountain cities can be reached directly by planes which deposit travelers a mile or more above sea level. This can result in altitude sickness due to hypoxemia, or reduced oxygen in the blood, caused by the unaccustomed exposure to the lower atmospheric pressure at high elevations. On a given day, the prevailing atmospheric pressure in Albuquerque, NM (elevation 1620 meters) might be 0.799 atm. Calculate this pressure expressed in mmHg and in torr. Relationship between altitude and barometric pressure.

Answers

Answer:

See explanation

Explanation:

To convert from atm to mmHg

1 atm = 760 mmHg

0.799 atm = 0.799 atm * 760 mmHg/1 atm = 607.24 mmHg

To convert from atm to torr

1 atm = 760 torr

0.799 atm = 0.799 atm * 760 torr/1 atm = 607.24 torr

Briefly describe each of the suns layers. I’ll give brainless

Answers

Answer:  The inner layers are the Core, Radiative Zone and Convection Zone.

The outer layers are the Photosphere, the Chromosphere, the Transition Region and the Corona.

Nuclear fusion of hydrogen in the core of the Sun produces tremendous amounts of energy that radiate out from the Sun.

The corona is the outermost layer of the Sun, starting at about 1300 miles (2100 km) above the solar surface (the photosphere). The temperature in the corona is 500,000 K (900,000 degrees F, 500,000 degrees C) or more.

The chromosphere is a layer in the Sun between about 250 miles (400 km) and 1300 miles (2100 km) above the solar surface (the photosphere). The temperature in the chromosphere varies between about 4000 K at the bottom (the so-called temperature minimum) and 8000 K at the top (6700 and 14,000 degrees F, 3700 and 7700 degrees C), so in this layer (and higher layers) it actually gets hotter if you go further away from the Sun, unlike in the lower layers, where it gets hotter if you go closer to the center of the Sun.

The photosphere is the deepest layer of the Sun that we can observe directly. It reaches from the surface visible at the center of the solar disk to about 250 miles (400 km) above that. The temperature in the photosphere varies between about 6500 K at the bottom and 4000 K at the top (11,000 and 6700 degrees F, 6200 and 3700 degrees C)

What is the molarity of a solution made from dissolving 3.0 moles of Saline (NaCl) in 0.25 L of solution?

Answers

Answer: the answer is 12M

Explanation: 3.0mol/ 0.25L =12M

12M is the molarity of a solution made from dissolving 3.0 moles of Saline (NaCl) in 0.25 L of solution.

What is molarity?

The amount of molecules of molecules divided by the quantity of liters in solution is the definition of molarity, a concentration unit in chemistry. It is crucial to comprehend how it is calculated as well as when to employ it in comparison to other units because it is among the most widely used concentration units.

A chemical solution's concentration is measured in molarity (M). It refers to the solute's moles per liter of solution. To be clear, this is not the same as the liters of solvents (a common mistake).

molarity = number of moles of solute/ volume of solution in litre

molarity =3.0mol/ 0.25L

             =12M

Therefore, 12M is the molarity of a solution made from dissolving 3.0 moles of Saline (NaCl) in 0.25 L of solution.

Suppose Rutherford's lab was 10 meters (m) long and the speed of an alpha particle is 3.0x10^8 meters per second (m/s). How much time would he plan on the alpha particles taking to move from the alpha particle source to the gold foil target? Write it in a mathematical equation

Answers

Answer:

t = d/v , 33.3 ns

Explanation:

Since distance, d = vt where v = speed and t = time taken to cover the distance.

Since the distance, d covered by the alpha particle is the length of Rutherford's lab which is 10 m long and the speed of the alpha particle is v = 3 × 10⁸ m/s, the time, t it takes the alpha particle to move from the alpha particle source to the gold foil target is thus

t = d/v

= 10 m/3 × 10⁸ m/s

= 10/3 × 10⁻⁸ s

= 3.33 × 10⁻⁸ s

= 33.3 × 10⁻⁹ s

= 33.3 ns
