The Tropical Zone experiences Tradewinds. True or false?
Answer:
It is true , that the tropical zone experiences the trade winds .
Explanation:
TRADE WINDS -: The trade winds or easterlies are the dominant east-to - west permanent winds that flow in the equatorial area of the Planet (between latitudes 30 ° N and 30 ° S). In the Northern Hemisphere, the trade winds blow primarily from the northeast and from the southeast in the Southern Hemisphere, strengthening throughout the winter and when the Arctic oscillation is in its warm phase. Trade winds have been used by sailing ship captains for centuries to cross the world's oceans and have enabled colonial expansion into the Americas and the construction of trade routes across the Atlantic and Pacific oceans. They act as the steering flow for tropical storms in meteorology. developing over the Atlantic , Pacific, and Southern Indian Oceans and landing in North America, Southeast Asia, Madagascar, and East Africa. Under trade wind regimes, shallow cumulus clouds are seen and are capped from being larger by a trade wind inversion induced by downward air aloft from within the subtropical ridge.
When trade winds blow through tropical areas , due to more direct sunlight , air masses heat up across lower latitudes. Those that develop over (continental) land are drier and hotter than those that develop over (maritime) oceans and travel northward to the subtropical ridge 's western periphery. Masses of maritime tropical air are often referred to as masses of commercial air. There are extensive areas of trade winds in all tropical oceans except the northern Indian Ocean.
Hence , the statement is true.

Calcule la masa de un líquido con una densidad de 2.5 g/mL y un volumen de 15 mL.
A. 375 g
B. 3.75 g
C. 37.5 g
Answer:
The answer is option CExplanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volumeFrom the question
volume of liquid = 15 mL
density = 2.5 g/mL

how can i find the sum of 18236.34+3244213-7654=
Answer:
3250113.34
Explanation:
Align decimals together
If the other numbers don't have decimals, you can add a decimal and zeros after the decimal as it means the same thing
2 1 1 1
18236.34
3244223.00
+ 7654.00
3250113.34 is the answer
Answer:
-3254795.34
Explanation:
you add 18236.34 and 3244213 and get 3262449.34
then you subtract 7654 from 3262449.34 and get -3254795.34
The half-life of Zn-71 is 2.4 minutes. If one had 100.0 g at the beginning, how many grams would be left after 7.2 minutes has elapsed?
7.2 / 2.4 = 3 half-lives
(1/2)3 = 0.125 (the amount remaining after 3 half-lives)
100.0 g x 0.125 = 12.5 g remaining

please help if u can ty..
Answer:
a) [tex]BaF_{2}[/tex]
b) [tex]SnCl_{4}[/tex]
c) [tex]Cr_{2}O_{3}[/tex]
d) [tex]FeO[/tex]
e) [tex]Li_{3} P[/tex]
Explanation:
The charges of the ions have to be 0, so they balance.
a) [tex]Ba^{2+}[/tex] has the charge of +2 and [tex]F^{-}[/tex] has the charge of -1. So its [tex]0=(+2)+(-1)*2[/tex]. That means you need one [tex]Ba^{2+}[/tex] and two [tex]F^{-}[/tex] to balance the equation. -> [tex]BaF_{2}[/tex]
b) [tex]Sn^{4+}[/tex] has the charge of +4 and [tex]Cl^{-}[/tex] has the charge of -1. So its [tex]0=(+4)+(-1)*4[/tex]. That means you need one [tex]Sn^{4+}[/tex] and four [tex]Cl^{-}[/tex] to balance the equation. -> [tex]SnCl_{4}[/tex]
c) [tex]Cr^{3+}[/tex] has the charge of +3 and [tex]O^{2-}[/tex] has the charge of -2. So its [tex]0=(+3)*2+(-2)*3[/tex]. That means you need two [tex]Cr^{3+}[/tex] and three [tex]O^{2-}[/tex] to balance the equation. -> [tex]Cr_{2}O_{3}[/tex]
d) [tex]Fe^{2+}[/tex] has the charge of +2 and [tex]O^{2-}[/tex]has the charge of -2. So its [tex]0=(+2)+(-2)[/tex]. That means you need one [tex]Fe^{2+}[/tex] and one [tex]O^{2-}[/tex] to balance the equation. -> [tex]FeO[/tex]
e) [tex]Li^{+}[/tex] has the charge of +1 and [tex]P^{3-}[/tex]has the charge of -3. So its [tex]0=(+1)*3+(-3)[/tex]. That means you need three [tex]Li^{+}[/tex] and one [tex]P^{3-}[/tex] to balance the equation. -> [tex]Li_{3} P[/tex]

What is the exponent when you convert 0.000978 into scientific notation
A. 4
b. -4
c. 3
d. -6
.. HELPPPPP
Answer:
B: -4
Explanation:
0.000978
0.00978(x10)
0.0978(x10x10)
0.978(x10x10x10)
9.78(x10x10x10x10)
9.78 X (10^4)
9.78X10^-4
because you move the decimal to the left it becomes negative 4
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10 If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Compound Lattice Energy (kJ/mol) Compound Lattice Energy (kJ/mol) LiF 1030 NaCl 788 LiCl 834 MgCl2 2326 LiI 730 AlCl3 5376 Lattice Energy 1 Lattice Energy 2 For the lattice energies given above … in Lattice Energy 1, explain why LiF has a greater lattice energy than LiI in Lattice Energy 2, explain why NaCl has a smaller lattice energy than AlCl3
Answer:
The lattice energy decreases down the group and increases across the period, therefore, the lattice energy of LiF > lattice energy of LiI, and the lattice energy of NaCl < the lattice energy of AlCl₃
Explanation:
The given parameters are;
Compound [tex]{}[/tex] Lattice Energy (kJ/mol)
LiF [tex]{}[/tex] 1030
NaCl [tex]{}[/tex] 788
MgCl₂ [tex]{}[/tex] 2326
LiI [tex]{}[/tex] 730
AlCl₃ [tex]{}[/tex] 5376
Lattice is the energy that must be added in order to split one mole of a ionic solid compound into gaseous ions
Given that the force of attraction between charges is inversely proportional to the square of the distance separating the charges, we have that as the atomic radius increases progressively down the group, the lattice energy decreases, therefore, LiF which has a shorter inter nuclear distance than LiI due to fluorine, F, being higher up on the periodic table than iodine, I, has a greater lattice energy than LiI
Similarly, given that the atomic radius decreases across the period, and that sodium, Na, comes before aluminum, Al, as we move across period 3, of the periodic table, the inter nuclear distance between atoms of in NaCl is larger than the internuclear distances between the atoms of AlCl₃, as well as the presence of more chlorine atoms in AlCl₃ than in NaCl, the lattice energy of NaCl is smaller than the lattice energy of AlCl₃.
