This phenomenon of difference in precipitation on earth and ocean surface is due to a variety of factors.
First of all, gravity allows any water from the Earth's surface to flow into the ocean. In the ocean, there are glaciers as well that can melt.
The ocean, the atmosphere, and the land all continuously exchange moisture as part of the water cycle.
Over the ocean, weather patterns develop and dissolve more slowly than over land, hence there is greater atmospheric circulation there. As a result, additional clouds are forming.
What is water cycle? The steady evaporation of ocean water raises the ambient air's temperature and humidity, resulting in the formation of rain and storms that are then carried by trade winds. In actuality, the majority of rain that falls on land originates in the ocean.For more information on water cycle kindly visit to

9. Circle the atom in each pair that has the greater ionization energy.
A) Li or Be
B) Ca or Ba
C) Na or K
D) P or Ar
E) Cl or Si
F) Li or K
A) Be
B) Ca
C) Na
D) Ar
E) Cl
F) Li
This question simply deals with ionization energy trends across the periodic table or down the group.
Ionization energy is the energy that is needed to remove an electron from its orbital around an atom in such a manner that it will no longer be associated with that same atom.
Now, from studies, it has been found that Ionization energy decreases down a group but it tends to increase as we go from the left to right going across the periodic table.
A) Li(Lithium) and Be(Berrylium) belong to the same period which is period 2 on the periodic table. Berrylium comes after berrylium in that period and as such from the rule earlier, berrylium will have the greater ionization energy.
B) Ca(Calcium) and Ba(Barium) belong to the same group 2 in the periodic table with barium further down the group. Thus, from the trend, Ca(Calcium) will have the greater ionization energy.
C) Na(Sodium) and K(Potassium) belong to the same group 1 in the periodic table with potassium further down the group. Thus, from the trend, Na(Sodium) will have the greater ionization energy.
D) P(Phosphorus) and Ar(Argon) belong to the same period which is period 3 on the periodic table. Argon comes after Phosphorus in that period and as such from the rule earlier, argon will have the greater ionization energy.
E) Cl(Chlorine) and Si(Silicon) belong to the same period which is period 3 on the periodic table. Cl(Chlorine) comes after Si(Silicon) in that period and as such from the rule earlier, Cl(Chlorine) will have the greater ionization energy.
F) Li(Lithium) and K(Potassium) belong to the same group 1 in the periodic table with potassium further down the group. Thus, from the trend, Li(Lithium) will have the greater ionization energy.

In the reaction above, how many moles of sodium chloride would be produced
if you started with 20 grams of magnesium chloride and excess sodium
phosphate? The equation is not balanced.
(If anyone can answer in depth if appreciate it )
Answer:
24.5 g of NaCl
Explanation:
We begin from the balanced reaction:
3MgCl₂ + 2Na₃PO₄ → 6NaCl + Mg₃(PO₄)₂
If the sodium phosphate is in excess, then the limting reagent is the magnessium chloride.
We convert mass to moles:
20 g . 1mol / 95.2g = 0.210 moles.
3 moles of MgCl₂ can produce 6 moles of NaCl
0.210 moles of salt, may produce (0.210 . 6) /3 = 0.420 moles
Ratio of reactant is twice the product
We convert the moles to mass:
0.420 mol . 58.45 g/mol = 24.5 g

define the term pure substance
Answer:
Pure substances are substances that are made up of only one kind of particles and has a fixed or constant structure. Pure substances are further classified as elements and compounds. An element is a substance that consists of only one type or kind of atom
Answer:
define the term pure substance :
A pure substance does not have to be of a single element or compound, This can either be one single element or one single compound, but every sample of this substance that you examine must contain exactly the same thing with a fixed, definite set of properties
Explanation:
Complete the sentence:

Why does the moon have a stronger gravitational effect on the earth then the sun?
Explanation:
The tidal forces of the Moon are much stronger than the Sun's because it is so much closer to our planet, causing a much greater variation in the gravitational force from one location to another. The Sun's gravitational force, on the other hand, varies much less because the Sun is so far.
Please mark me has brainliestA reaction is first order with respect to reactant A and second order with respect to reactant B. Starting with [A] = 0.175 M and [B] = 0.00250 M, the reaction rate is 2.83 x 10−5 M.S−1. What is the rate constant k? Show your work.
Answer:
[tex]k=25.9M^{-2}s^{-1}[/tex]
Explanation:
Hello there!
In this case, since rate laws are written by considering the rate constant, concentration and specific orders of reaction of the concentration of the species contributing to the rate of reaction, we write:
[tex]r=k[A][B]^2[/tex]
Since it is first-order with respect to reactant A and second-order with respect to reactant B. In such a way, given the rate and concentrations of both A and B, the involved rate constant k turns out to be:
[tex]k=\frac{r}{[A][B]^2} \\\\k=\frac{2.83x10^{-5}M/s}{(0.175M)(0.00250M)^2}\\\\k=25.9M^{-2}s^{-1}[/tex]

What is the average speed of a race car if it travelled a total of 500 miles in 3.5 hours
Answer:
speed = 142.8571 miles per hour OR 142.8571 mi/h
Explanation:
speed= [tex]\frac{distance}{time}[/tex]
distance = 500, time = 3.5hours or 210 minutes
speed= [tex]\frac{500}{210}[/tex] = 142.8571
