The atmospheric conditions required for the formation of clouds are , air needs only to be cooled to saturation and beyond formation of clouds and precipitation.
What is precipitation?
Precipitation is defined as any liquid or frozen water which forms in the atmosphere and then gets received on Earth.It is one of the most important steps of the water cycle.
Precipitation takes place in form of clouds when water vapor gets accumulated in clouds and they get bigger and heavy, when the clouds become heavy enough they fall to the land in the form of rain.f a cloud is present at higher altitudes , the water present in the clouds freezes and fall to the ground in form of snow,hail.
Precipitation occurs always in case of fresh water because the sea salt does not evaporate with the water.The different types of precipitation are rain, drizzle,snow,snow hail,etc.

Answer:
WHY: You can abbreviate an element's electron configuration using the noble gas notation method because when you get down to the lower elements, specifically the d's and the f's, the electron configuration will be very long. The noble gas notation method is a faster answer while also being correct.
HOW: We can abbreviate an element's electron configuration by finding the last noble gas a specific element passed, for example calcium would have just passed Argon. Once you have the "address" of the previous noble gas, then you add on the difference between the element chosen and the noble gas, for example calcium would be [Ar] 4s^2.

N2 + 3H2, -> 2NH3
If I have 50.6 L of N2 and excess H2, how many liters of NH3 can I produce?
Answer:
C. 101.2 L
Explanation:
N2 + H2= NH3
Balancing it,
N2 + 3 H2 = 2.NH3
(1 mol) (3 mol) (2 mol)
which means
1 molecule of nitrogen reacts with 3 molecule of hydrogen to form ammonia.
Likewise,
50.6 l of nitrogen reacts with 50.6 × 3= 151.8 l of hydrogrn to form 50.6 × 2= 101.2 l of ammonia.

Use the solubility table to predict if a precipitate will form in the double replacement reaction. if yes identify the precipitate.
CuSO4 + 2KOH -> Cu(OH) + K2SO4
Answer:
A precipitate will be formed, it will be Cu(OH)2.
Explanation:
This is due to it's solubility.
There will be a precipitate due the solubility which will be result in the Cu(OH)2 precipitate.
What is double replacement reaction?A double replacement reaction is a chemical reaction in which two reactant and product exchange cations or anions to produce two new products.
Double replacement reactions are also referred to as double displacement reactions or metathesis reactions.
The simplest way to detect a double displacement reaction is to see if the cations exchanged anions with one another.
If the states of matter are mentioned, look for soluble reactants and the creation of a single solid product, as the reaction typically produces a precipitate.
As a result of the solubility, a precipitate will form, resulting in the Cu(OH)2 precipitate.
Thus, this is the result of the reaction.

which physical method can separate a mixture of steel ball bearings and marbles? boiling evaporation filtration
Steel ball bearings and marbles can be separated through manual sorting due to their difference in appearance.
Before answering the question, let us define the given choices.
The boiling separation technique is used when the boiling points of the components of a mixture are different. It is mostly done for the separation of homogeneous mixtures. The evaporation separation technique is usually used for the separation of a solvent and a soluble solid. Enough heat is provided for the solvent to be evaporated. The process is also slower compared to the boiling separation technique. Filtration is used to separate insoluble solid particles from the liquid. Materials such as filter paper are used in this process.The given separation techniques are not suitable for the separation of steel balls bearings, and marbles. Instead, the sorting separation technique must be used. This is used for manually sorting coarse materials based on their physical characteristic, which in this case is their difference in appearance.

alculate the molarity of a solution that contains 20.0grams of sodium hydroxide in 200. ml of solution.
The molarity of a solution that contains 20.0grams of sodium hydroxide in 200. ml of solution is 2.3 M.
What is Molarity?Molarity is defined as the ratio of number of moles of solute to the volume of the solution.
Molarity = number of moles of solute/ Volume of solution
Given,
given mass of sodium hydroxide= 20 g
Volume of the solution = 200 mL.
Firstly, we will calculate the moles of sodium hydroxide.
What is Mole?Mole is defined as the ratio of given mass of substance to the molar mass of substance.
Mole = given mass/ molar mass
Molar mass of sodium hydroxide = 40 g
Mole = 20/40
= 0.5 mol
Molarity = (0.5/ 200) × 1000 = 2.5M
Thus, we calculated that the molarity of a solution that contains 20.0grams of sodium hydroxide in 200. ml of solution is 2.3 M.

the melting point of scandium fluoride is 1552°c, explain why scandium fluoride has a high melting point.
Answer:
Scandium(III) fluoride, ScF3, is an ionic compound. It is slightly soluble in water but dissolves in the presence of excess fluoride to form the ScF63− anion.
hope it will help you......
A high melting point is caused by a high fusion heat, a low fusion entropy, or a blend of the two. The crystal phase of highly symmetrical molecules is densely packed with many efficient intermolecular interactions, resulting in a higher enthalpy change on melting.
What is intermolecular force?An intermolecular force is a force that mediates the interaction of molecules, including electromagnetic forces of attraction or repulsion that act between atoms and other types of neighboring particles, such as atoms or ions.
The intermolecular forces can be in order of strength, ion-dipole, hydrogen bonding, dipole-dipole, and Van der Waals forces.
Because it is the power of attraction or repulsion between atoms or molecules rather than the ability to share or give/take electrons.
ScF3, or Scandium(III) fluoride, is an ionic compound. It is only slightly soluble in water, but in excess fluoride it dissolves to form the ScF63 anion.
Thus, due to the strong intermolecular forces, it have high melting point.

What is the percent yield if 155 grams of calcium carbonate is treated with 250 grams of hydrichloric acid andb142 grams of calciym chloride is obtained
Answer:
375 grams
Explanation:
The percent yield if 155 grams of calcium carbonate is treated with 250 grams of hydrochloric acid and 142 grams of calcium chloride is obtained is 82.55%
What is percent yield?Percent yield is defined as the amount of product actually made compared with the maximum calculated yield. It is the ratio of actual yield to the theoretical yield.
Mass of calcium carbonate = 155 g
Mass of HCl = 250g
Mass of calcium chloride product = 142 g
Moles of calcium carbonate = 155 / 100 = 1.55 moles
Moles of HCl = 250 / 36.5 = 6.85 moles
Mass of calcium chloride = Moles x Molar mass
= 1.55 mole x 111 g/ mole
= 172 g /mole
Theoretical yield = 172 g
Actual yield = 142 g
Percent yield = Actual yield / Theoretical yield x 100
= 142 / 172 x 100
= 82.55 %
Thus, the percent yield if 155 grams of calcium carbonate is treated with 250 grams of hydrochloric acid and 142 grams of calcium chloride is obtained is 82.55%
