The Coriolis effect is the acceleration of the objects with the moving earth. The Coriolis effect affects both deep water and surface currents in the ocean.
What is the Coriolis effect?The Coriolis effect (also known as the Coriolis force).
It describes the apparent deflection of items traveling in a straight line relative to the Earth's surface (such as airplanes, wind, missiles, and ocean currents).
The Coriolis effect is the acceleration of the objects with the moving earth.
Thus, The Coriolis effect impacts both deep water and surface currents in the ocean.

If 2.2 moles of calcium oxide are decomposed, how many moles of oxygen are produced?
2CaO --> 2Ca + O2
Answer: Since the reaction is 2Ca(NO3)2 = 2CaO + 4NO2 + O2
1) - given the stoichiometric coefficients, we know that 2 moles of Ca(NO3)2 will produce 4 moles of NO2, hence, 1 mole will produce 2 moles of NO2
2) - 328 g produces 22.4 L, since One mole of any gas at S.T.P. occupies the same volume which is 22.4 L.
Hence, 65.6 g produces (65.6*22.4)/328 = 4.48 L
3) - 328 g produces 112 g CaO. Therefore, 65.6 g produces = (65.6*112)/328 = 22.4 g CaO.
4) - Given the stoichiometric coefficients, we know 5 moles of gaseous products are already being produces ( 4+1) by 2 moles of reactant.
5) - 44.8 L at STP = 2 moles of NO2, since One mole of any gas at S.T.P. occupies the same volume which is 22.4 L.
Hence, to produce 2 moles of NO2, we need 1 mole of reactant = 164 g

how does lanthanide contraction influence the density of period 6 transition element
Answer:
For example, the atomic radius of the metal zirconium, Zr, (a period-5 transition element) is 155 pm (empirical value) and that of hafnium, Hf, (the corresponding period-6 element) is 159 pm. ... The increase in mass and the unchanged radii lead to a steep increase in density from 6.51 to 13.35 g/cm3.

which of the following is unbalanced
A. SnO2 + H2 → Sn + 2 H2O
B. 2Na + 2H2O → 2NaOH + H2
C. N2O5 + H2O → HNO3
D. 2Fe + 3Cl2 → 2FeCl3
Answer:
The unbalanced chemical equation is;
C. N₂O₅ + H₂O → HNO₃
Explanation:
In balancing a chemical reaction equation, only the coefficients of the terms of the reactants and/or the products are adjusted (and not the subscripts to the atoms in the compounds) to ensure that the total number of each element is the same on either side of the arrow for the chemical reaction
A coefficient term is the number multiplier of the compounds and elements in a chemical reaction
Therefore, the balanced chemical equation is obtained by changing the coefficient of the product from the implied '1' to a '2' as follows;
N₂O₅ + H₂O → 2HNO₃

Which two particles can form an ionic bond with each other?
A.
a negative oxygen ion and a negative chlorine ion
B.
a positive sodium ion and a positive magnesium ion
C.
a positive calcium ion and a negative oxygen ion
D.
a neutral fluorine atom and a negative sulfur ion
Answer:
C. a positive calcium ion and a negative oxygen ion
Explanation:
Ionic bonds are generally positive and negative because one is gaining electrons while the other is losing.
The term chemical bond generally refers to the attractive force that holds the constituent atoms or ions of a molecular species together. Here an ionic bond is formed between a positive calcium ion and a negative oxygen ion. The correct option is C.
What is an ionic compound?An ionic compound is formed by the transfer of one or more electrons between the atoms. An ionic bond or electrovalent bond refers to the strong electrostatic forces of attraction that hold together oppositely charged ions.
The number of electrons lost or gained by an atom of an element so as to acquire a stable octet configuration in its outermost shell is called the electrovalency of the element.
Here 'Ca' has 20 valence electrons and 'O' has 6 valence electrons. So in order to attain the stable octet configuration of 'Ar', 'Ca' loses two electrons whereas 'O' accepts two electrons to attain stable octet configuration of 'Ne'.
Thus the correct option is C.

Choose ALL that apply
lesson 2.09
Question 7 options:
As a result, air near the equator heats up and rises because it is less dense.
The sun's energy heats air at the equator more than it does at the poles.
Radiant energy from the sun strikes Earth unevenly.
As it rises, it cools and begins to flow toward the poles. As this air leaves the equator, cooler and heavier air from the poles flows along the surface to take its place.
i’m pretty sure it all of them!
ALL options above described can impact the wind patterns.
Wind patterns are completely dependent on the amount of heat present in the environment, which is influenced by sun rays.The sun rays are perpendicular near the Equator, thereby increasing the temperature of the air and changing win patterns.As air rises, it cools and travels to higher latitudes (i.e. toward the poles).In conclusion, ALL options above described can impact the wind patterns.

Why is it important to have the correct atomic number when identifying an atom/element?
Answer:
The number of protons in an atom is called its atomic number. This number is very important because it is unique for atoms of a given element. All atoms of an element have the same number of protons, and every element has a different number of protons in its atoms.

You bought a balloon for a birthday party in January. It was so cold outside that you ran into the house and forgot the balloon in the car. You go out to the car a few hours later and get the balloon. You noticed that the balloon was a little deflated. Once you brought the balloon into the house, after about 20 minutes, the balloon was back to normal.
Part A: Explain what happened to cause the balloon to deflate and then inflate. Be sure to use unit vocabulary and specific details to support your answer.
Part B: Using the information you provided in Part A, explain what would happen if you left an inflated balloon in the car on a very hot summer day.
Answer:
Part A: When air is left in specific environments, it can either expand or contract depending in the given environment, so, if left in a cold car for a few hours, the air inside said balloon will contract.
Part B: If left in said car on a very hot summer day, the air in said balloon will expand, and if left in said car long enough, said balloon will explode due to the air inside expanding
