The Answer is Precipitation
Explanation:
Look it up on and then also got it right on the Unit Test and the Quiz.
The diagram illustrates the water cycle, the process that occurs at location W is precipitation. The correct option is a.
What is precipitation?Precipitation is any product of the condensation of atmospheric water vapour that falls under gravitational pull from clouds. The main forms of precipitation include drizzle, rain, sleet, snow, ice pellets, graupel and hail.
Precipitation occurs when a portion of the atmosphere becomes saturated with water vapour so that the water condenses and precipitates or falls. Thus, fog and mist are not precipitation but colloids, because the water vapour does not condense sufficiently to precipitate. Two processes, possibly acting together, can lead to air becoming saturated: cooling the air or adding water vapour to the air. Precipitation forms as smaller droplets coalesce via collision with other raindrops or ice crystals within a cloud. Short, intense periods of rain in scattered locations are called showers.
Precipitation is a major component of the water cycle and is responsible for depositing the fresh water on the planet.

Answer:
According to the laws of thermodynamics, Molecular movements of particles will tend to move into state of lower energy and this would mean that knowing the vibrational and translational energy of complex molecules will lose and give off energy usually in the form of heat but also sound and other transferable mediums it will tend to become less energetic and this mobile indicative of colder objects, if examining the average Molecular kinetic energy and bond energies of the compounds in question.

4. How many moles of H, would be
produced from 47 grams of H2SO4?
2A1 +3H,504 → Al2(SO4)3 +3H2
Answer:
0.48 moles of H₂ are produced.
Explanation:
Given data:
Number of moles of H₂ produced = ?
Mass of H₂SO₄ = 47 g
Solution:
Chemical equation:
2Al + 3H₂SO₄ → Al₂(SO₄)₃ + 3H₂
Number of moles of H₂SO₄ :
Number of moles = mass/molar mass
Number of moles = 47 g/ 98 g/mol
Number of moles = 0.48 mol
Now we will compare the moles of H₂SO₄ and H₂
H₂SO₄ : H₂
3 : 3
0.48 : 0.48
Thus, 0.48 moles of H₂ are produced.

What will happen if you add salt to water that is "saturated"? *
The salt will react with the water quicker because you're adding more reactants.
The added salt will sink to the bottom.
The salt will dissolve more slowly than usual.
Dissolved salt will precipitate out and sink to the bottom.
Answer:
The added salt will sink to the bottom
Explanation:
A saturated solution is that solution that contains the maximum amount of solute it can dissolve and ,hence, will no longer dissolve any more solute. This question is describing a water solution that is "saturated", this means that water can no longer dissolve any more solute because it has reached the maximum solute limit it can contain.
Hence, adding more solute to a saturated solution like the WATER being described in this question will result in the solute forming a PRECIPITATE at the bottom of the solution. Hence, in this water solution, adding salt to the saturated water solution will result in the added salt sinking to the bottom.

Describe an every day example of an object that has energy of motion and object that has stored energy
Answer:
Humans
Explanation:
Humans have energy of motion and store energy.
Every object will have any form of energy. For instance, when we are walking we gains a kinetic energy. We use electronic devices where electrical energy is stored and can be converted to mechanical energy to activate any motors.
What is energy transformation?Energy can neither be created nor be destroyed. However it can be transformed to any other forms. Thus, the total energy will conserved always.
We have a lot of example for energy transformation and storage. The energy form stored by virtue of the position of an object is called potential energy. Whereas, when the object starts moving potential energy converts to kinetic energy.
Thus, thermal vibrations of particles, our every day activities all are associated with a kinetic energy. Kinetic energy of each body depends on the mass and velocity of the body. The more the mass and velocity more will be the kinetic energy.

Why chloride described as an extended structure?
Answer:
Explanation:
Examples of extended structures could include sodium chloride or diamonds. Examples of molecular-level models could include drawings, 3D ball and stick structures, or computer representations showing different molecules with different types of atoms.]
Chloride is described as an extended structure because its atoms are arranged following an endless repeating pattern and are of distinct ratio
Crystals and polymers mostly form extended structures as seen in the formation of sodium chloride whereby the ions in the compound are arranged following a repeating pattern. ( i.e. has a giant ionic structure ).
Chloride is a considered an extended structure because in sodium chloride it forms an unending repeated pattern of ions which makes it a perfect example of an extended structure.
Hence we can conclude that Chloride can be described as an extended structure because its atoms are arranged following a repeating pattern and are of distinct ratio.

If scientists had tried to repeat thomosons experiment and found that they could not would thomosons cocnclusion still have been valid?
Answer:
No
Explanation:
The conclusions from Thomoson's claims would be invalid if his experiment could not be replicated.
One of the attributes of a valid experiment in science is replication. That is, an experiment must be repeatable with similar outcomes under similar conditions as the original experiment when independently performed by another scientist. Once an experiment cannot be replicated, the outcomes of such an experiment become invalid in science.
Hence, Thomoson's conclusion would be invalid if his experiment could not be replicated.

A compound has a molar mass of 100 g/mol and the percent composition (by mass) of 65.45% C, 5.45% H, and 29.09% 0. Determine the empirical formula and the molecular formula.
A) CHO and C6H6O6
B) C3H3O and C6H6O2
C) C3HO and C6H2O2
D) CH2O and C4H8O4
E) CH4O and C3H12O3
Answer:
B) C3H3O and C6H6O2
Explanation:
Given data:
Molar mass of compound = 100 g/mol
Percentage of hydrogen = 5.45%
Percentage of carbon = 65.45%
Percentage of oxygen = 29.09%
Empirical formula = ?
Molecular formula = ?
Solution:
Number of gram atoms of H = 5.45 / 1.01 = 5.4
Number of gram atoms of O = 29.09/ 16 = 1.8
Number of gram atoms of C = 65.45 / 12 = 5.5
Atomic ratio:
C : H : O
5.5/1.8 : 5.4/1.8 : 1.8/1.8
3 : 3 : 1
C : H : O = 3 : 3 : 1
Empirical formula is C₃H₃O.
Molecular formula:
Molecular formula = n (empirical formula)
n = molar mass of compound / empirical formula mass
Empirical formula mass = 12×3 + 1.01 ×3 + 16×1 = 55.03
n = 100 / 5503
n = 2
Molecular formula = n (empirical formula)
Molecular formula = 2 (C₃H₃O)
Molecular formula = C₆H₆O₂
If a balloon containing 3000 L of gas at 39°C and 99 kPa rises to an altitude where the pressure is 45.5 kPa and the temperature is 16°C,

Further explanationGiven
3000 L of gas at 39°C and 99 kPa to 45.5 kPa and 16°C,
Required
the new volume
Solution
Combined with Boyle's law and Gay Lussac's law
[tex]\tt \dfrac{P_1.V_1}{T_1}=\dfrac{P_2.V_2}{T_2}[/tex]
T₁ = 39 + 273 = 312
T₂ = 16 + 273 = 289
Input the value :
V₂ = (P₁V₁.T₂)/(P₂.T₁)
V₂ = (99 x 3000 x 289)/(45.5 x 312)
or we can write it as:
V₂ = 3000 L x (289/312) x (99/45.5)
Why is it important to know the temperature of the water when dealing with ions in
an aqueous solution?
Water does not ionize at higher temperatures.
Water becomes very acidic when at low temperatures.
Temperature affects the concentration of water.
The ionization constant of water is usually given at 25 °C.
Water at a higher temperature will produce more ions than water at a lower temperature.
