8. How does water vapor get into the troposphere in the first place?
Answer:
Water vapor enters the atmosphere through evaporation from water bodies (oceans, seas, lakes, rivers), ice/snow cover and soil, as well as through evapotranspiration from vegetation
Explanation:
The cycle, which occurs in the troposphere, begins as the sun evaporates large amounts of water from the earth's surface and the moisture is transported to other regions by the wind. As air rises, expands, and cools, water vapor condenses and clouds develop

How many moles of magnesium is 3.01 x 1022 atoms of calcium?
preferably a step by step answer....thank u<3
Answer:
0.03 mol
Explanation:
The equation relating the number of moles and number of atoms is:
Number of atoms = number of moles × 6.02 × 10²³
[6.02 × 10²³ is the Avogadro's constant and is the number of particles in 1 mole of any substance.]
By rearranging the equation, we can find the number of moles of calcium.
Number of moles = (3.01 × 10²²) ÷ (6.02 × 10²³)
Number of moles = 0.05 moles of calcium
Now the only data we know about these two elements are their Mr values, so we are going to find the number of moles of magnesium using ratio.
Moles : Mr
0.05 mol : 40.1
x : 24.3
[we are going to assume that x is the number of moles of magnesium that we have to find out.]
Cross multiply the ratios.
40.1x = 0.05 × 24.3
x = 1.215 ÷ 40.1 = 0.03 mol
A reaction proceeds with 2.72 moles of magnesium chlorate and 3.14 moles of sodium hydroxide. this is the equation of the reaction: mg(clo3)2 2naoh → mg(oh)2 2naclo3. determine the theoretical amount of each product that the reaction will produce. the reaction will produce of magnesium hydroxide and of sodium chlorate.
The theoretical amount of each product obtained are:
1.57 moles of Mg(OH)₂3.14 moles of NaClO₃Balanced equationMg(ClO₃)₂ + 2NaOH —> Mg(OH)₂ + 2NaClO₃
How to determine the limiting reactantFrom the balanced equation above,
1 mole of Mg(ClO₃)₂ reacted with 2 moles of NaOH
Therefore,
2.72 moles of Mg(ClO₃)₂ will react with = 2.72 × 2 = 5.44 moles of NaOH
From the calculation above, we can see that a higher amount (5.44 moles) of NaOH than what was given (3.14 moles) is needed to react completely with 2.72 moles of Mg(ClO₃)₂
Therefore, NaOH is the limiting reactant
How to determine the theoretical yield of Mg(OH)₂From the balanced equation above,
2 moles of NaOH reacted to produce 1 mole of Mg(OH)₂
Therefore,
3.14 moles of NaOH will react to produce = 3.14 / 2 = 1.57 moles of Mg(OH)₂
Thus, the theoretical yield of Mg(OH)₂ is 1.57 moles
How to determine the theoretical yield of NaClO₃From the balanced equation above,
2 moles of NaOH reacted to produce 2 mole of NaClO₃
Therefore,
3.14 moles of NaOH will also react to produce 3.14 moles of NaClO₃
Thus, the theoretical yield of NaClO₃ is 3.14 moles

Ionic Compounds have high boiling and melting points as they're very strong and require a lot of energy to break.The electrostatic forces of attraction between oppositely charged ions lead to the formation of ions.(c) If the ionic compound is dissolved in water, the ions in the solid separate and disperse uniformly
What is an ionic compound?Ionic compounds contain ions and are held together by the attractive forces among the oppositely charged ions.
An ionic bond is formed by the complete transfer of some electrons from one atom to another. The atom losing one or more electrons becomes a cation—a positively charged ion.
In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.
When ionic compounds dissolve in water, the ions in the solid separate and disperse uniformly throughout the solution.
