Answer:

V = 513.36m/s

Explanation:

Temperature (T) = 25°C = (25 + 273.15) = 298.15K

Speed (V) = 1.92*10³m/s

According to kinetic theory of gases, the speed (v) of a molecule is

V= √(3RT / M)

V = speed or velocity

R = ideal gas constant = 0.082J/mol.K

T = temperature of the gas

M = molar mass

Molar mass of hydrogen molecule = 2.0g/mol

Molar mass of Nitrogen molecule = (2×14.0) = 28.0g/mol

Since they're in the same temperature

V1 / V2 = √(M2 / M1)

1.92×10³ / V2 = √(28 / 2)

1.92×10³ / V2 = √(14)

1.92*10³ / V2 = 3.74

1.92*10³ = 3.74V2

V2 = 1920 / 3.74

V2 = 513.36m/s

The velocity of Nitrogen molecule is 513.36m/s

Answer & Explanation:

The molar mass of calcium chloride is 110.98 g/mol. We can use this information to solve this problem. We can set up our equation like this..

[tex]\frac{333 g(CaCl2)}{} *\frac{1mol(CaCl2)}{110.98g(CaCl2)}[/tex]

Multiply straight across on the top and straight across on the bottom.

[tex]\frac{333}{110.98}[/tex]

Now divide.

[tex]\frac{333}{110.98}=3.00[/tex]

So, there are 3.00 moles of calcium chloride contained in a 33 gram sample which is answer choice D.

Answer:

Cirrus

Cirrus cloudsCirrus clouds are delicate, feathery clouds that are made mostly of ice crystals. Their wispy shape comes from wind currents which twist and spread the ice crystals into strands.

Cirrostratus

Cirrostratus cloudsCirrostratus clouds are thin, white clouds that cover the whole sky like a veil. These clouds are most commonly seen in the winter, and can cause the appearance of a halo around the sun or the moon.

Cirrocumulus

Cirrocumulus cloudsCirrocumulus clouds are thin, sometimes patchy, sheet-like clouds. They sometimes look like they’re full of ripples or are made of small grains.

Mid-level Clouds (6,500-23,000 feet)

Altocumulus

Altocumulus cloudsAltocumulus clouds have several patchy white or gray layers, and seem to be made up of many small rows of fluffy ripples. They are lower than cirrus clouds, but still quite high. They are made of liquid water, but they don’t often produce rain.

Altostratus

Altostratus cloudsAltostratus clouds are gray or blue-gray mid-level clouds composed of ice crystals and water droplets. The clouds usually cover the entire sky.

Nimbostratus

Nimbostratus cloudsNimbostratus clouds are dark, gray clouds that seem to fade into falling rain or snow. They are so thick that they often blot out the sunlight.

Low Clouds (less than 6,500 feet)

Cumulus

Cumulus cloudsCumulus clouds look like fluffy, white cotton balls in the sky. They are beautiful in sunsets, and their varying sizes and shapes can make them fun to observe!

Stratus

Stratus cloudsStratus cloud often look like thin, white sheets covering the whole sky. Since they are so thin, they seldom produce much rain or snow. Sometimes, in the mountains or hills, these clouds appear to be fog.

Cumulonimbus

Cumulonimbus cloudCumulonimbus clouds grow on hot days when warm, wet air rises very high into the sky. From far away, they look like huge mountains or towers.

Stratocumulus

Stratocumulus cloudStratocumulus clouds are patchy gray or white clouds that often have a dark honeycomb-like appearance.

Special Clouds

Contrails

(Photo of white streaks of contrails in the sky) Contrails are made by high-flying jet airplanes. They are still clouds, though, because they are made of water droplets condensed from the water vapor in the exhaust of the jet engines.

Weather prediction: Contrails can provide information about the layers of moisture in the sky.

Mammatus clouds

Mammatus cloudsMammatus clouds are actually altocumulus, cirrus, cumulonimbus, or other types of clouds that have these pouch-like shapes hanging out of the bottom. The pouches are created when cold air within the cloud sinks down toward the Earth.

Orographic clouds

Orographic cloudsOrographic clouds get their shape from mountains or hills that force the air to move over or around them. They can also be formed by sea breezes and often appear as lines where two air masses meet.

Lenticular clouds

Lenticular clouds are shaped like lenses or almonds or...flying saucers! They may get their shape from hilly terrain or just the way the air is rising over flat terrain.

Answer:

11.81

Explanation:

We'll begin by writing the balanced dissociation equation for KOH. This is given below:

KOH —> K+ + OH-

Next, we shall determine the concentration of Hydroxide ion, [OH-]. This is illustrated below:

From the balanced equation above,

We can see that 1 mole of KOH produced 1 mole of OH-.

Therefore, 6.50x10^-3 M KOH will also produce 6.50x10^-3 M OH-.

Next, we shall determine the pOH of the solution. This is illustrated below:

pOH = –Log [OH-]

[OH-] = 6.50x10^-3 M

pOH = –Log 6.50x10^-3

pOH = 2.19

Finally, we can determine the pH of the solution as follow:

pH + pOH = 14

pOH = 2.19

pH + 2.19 = 14

Collect like terms

pH = 14 – 2.19

pH = 11.81

Therefore, the pH of the solution is 11.81

The pH of a 6.50 x 10-3 M KOH solution is 11.81 which is alkaline.

pH is a measure of how acidic or basic a solution is. Ph has a  range from 0 to 14. pHs with  less than 7 show  acidity, while a pH of greater than 7 indicates a base/ alkalinity. , pH of  7 shows the solution is neutral.

KOH is a strong base, Upon dissociation,it gives

KOH -> K⁺ + OH⁻

Here, 1 mole of KOH produced 1 mole of OH-.

Therefore, 6.50 x 10-3 M KOH will prodce 6.50 x 10-3 M H

Now, we first determine the pOH of the solution with the equation:

pOH = –Log [OH-]

[OH-] = 6.50x10^-3 M

pOH = –Log 6.50x10^-3

pOH = 2.19

Now, we know that  

pH + pOH = 14

Having gotten that  

pOH = 2.19,

pH + 2.19 = 14

pH = 14 – 2.19

pH = 11.81

Therefore, the pH of the KOH solution is 11.81 which is alkaline.

Explanation:

A landslide can be defined as a mass movement of material (e.g., rocks), which moves down a steep slope. A geologist is an expert that studies SLOW-MOVING landslides on a geological scale.

Landslides can occur suddenly or more slowly over long periods of time.

On a geological scale, landslides occur slowly so they are imperceptible to humans.

A geologist is a professional who investigates landslides on a geological scale, which is coarse on a human time-frame.

Answer:

Q= 29.2 J

Explanation:

22°C=295K

37°C=310K

Q= mC dT

Q= (15.0 g) *(0.130 J/g-K)* (310 K-295K)

Q= 29.2 J

29.2 J is required to raise the temperature of 15.0 g of lead from 22.0 °C to 37.0 °C.

The specific heat capacity is defined as the quantity of heat (J) absorbed per unit mass (kg) of the material when its temperature increases by 1 K (or 1 °C), and its units are J/(kg K) or J/(kg °C).

Given data:

22°C=295K

37°C=310K

Applying specific heat capacity formula:

Q= mC dT

Putting all the values in the formula:

Q= (15.0 g)  X (0.130 J/g-K) X (310 K-295K)

Q= 29.2 J

Hence, 29.2 J is required to raise the temperature of 15.0 g of lead from 22.0 °C to 37.0 °C.

# The main reason why the reaction above can not be balanced is:

   This chemical reaction SO2 + H2O -> H2SO2 is not correctly written.

    It must be: SO2 + H2O -> H2SO3

Explanation:

Note 1:

H2SO2 can be produced by the other chemical reaction:

2H2O + SCl2 -> 2HCl + H2SO2

....

Note 2: Answer A is false

As you can see in the reaction  SO2 + H2O -> H2SO3, the oxygen atoms are in two molecules on one side, but one in the other - However, this reaction is written correctly.

Note 3: Answer D is false

Of course the Sulfur atom must be placed in different places: in reactant and product molecules.

Note 4: Answer B is false

There are different kinds of chemical reactions, and this is normal that there are more molecules on one side than on the other.

The answer is C

The correct way to balance the reaction, would be to write it as SO2 + H2O →  H2SO3

Answer A is incorrect.

The oxygen atoms in the reaction SO2 + H2O -> H2SO3 are in two compounds on one end but on the other, it is in just one.

Answer D is wrong.

The sulfur atom has to be in the reactants and the products.

Answer B is not correct.

There are many types of chemical reactions . One side commonly has more atoms than the other.
