The coriolis effect is responsible for many large scale weather patterns. The coriolis force is responsible for the deflection of objects. It is this effect which drive the global wind and ocean circulation patterns. The correct option is C.
What is coriolis effect?The apparent effect produced by a rotating frame of reference is defined as the coriolis effect. This effect occurs when an object moving along a straight path is viewed from a non-fixed frame of reference.
Because of the earth's rotation, when an object moving in a straight path is viewed from earth, it appears to lose its course. So the travelling long distances around the earth appear to move at a curve instead of a straight line due to coriolis effect.
The coriolis effect is found to be strongest near poles and it is absent at the equator. The coriolis force is an apparent force caused by the rotation of earth.
Thus the correct option is C.

For most substances the density of a solid form is slightly greater than the density of liquid form water however is different it is slightly less dense in the solid form than it is in liquid form compare water in the solid form with neon argon in oxygen and proposal reason why solid water is less dense liquid water
Answer:
Answer: When water freezes, water molecules form a crystalline structure maintained by hydrogen bonding. Solid water, or ice, is less dense than liquid water. Ice is less dense than water because the orientation of hydrogen bonds causes molecules to push farther apart, which lowers the density.
Explanation:
The breakdown of a certain pollutant X in sunlight is known to follow first-order kinetics. An atmospheric scientist studying the process fills a 20.0Lreaction flask with a sample of urban air and finds that the partial pressure of X in the flask decreases from 0.473atm to 0.376atm over 5.6hours.
Calculate the initial rate of decomposition of X, that is, the rate at which Xwas disappearing at the start of the experiment.
Round your answer to 2 significant digits.
Answer:
0.019 atm / hr
Explanation:
Initial Concentration (Pressure) [A]o = 0.473 atm
Final Concentration (Pressure) [A] = 0.376 atm
Time = 5.6 hours
The breakdown follows first order kinetics.
The integrated rate law for a first order reaction is given as;
ln[A] = ln[A]o - kt
ln(0.376) = ln(0.473) - k (5.6)
ln(0.376) - ln(0.473) = - 5.6 k
5.6 k = 0.23
k = 0.0411 hr⁻¹
The rate of decomposition is given as;
Rate = k [X]
Where [X] represents Concentration (Pressure) = 0.473 atm
Rate = 0.0411 * 0.473 = 0.019 atm / hr

A sample of 0.600 mol of a metal M reacts completely with excess fluorine to form 46.8 g of MF2.?
a) How many moles of F are in the sample of MF2 that forms? (1.20 mol F)
b) How many grams of M are in this sample of MF2?
c) What element is represented by the symbol M? (Ca)
Answer:
See Explanation
Explanation:
Given:
moles M = 0.600 mole
moles F = excess (for rxn stoichiometry)
Formula Weight (F.Wt.) of F = 19 grams/mole (from Periodic Table)
Yield in grams = 46.8 grams (assuming theoritical yield)
Rxn: M + F₂ => MF₂
0.600mol Excess 0.600mol (1:1 rxn ratio for M:MF₂)
a. moles of F in MF₂ = 2(0.600) moles F = 1.2 moles F
b. mole weight MF₂ = 46.8g/0.600mol = 78g/mole
F.Wt. MF₂ = F.Wt. M + 2(F.Wt. F)
=> mass M = F.Wt. M = [F.Wt. MF₂ - 2(F.Wt. F)] = 78g/mol. - 2(19g/mol.)
= (78 - 38) grams/mole = 40 grams/mole
c. Calcium (Ca) has F.Wt. = 40 grams/mole (compared to Calcium on Periodic Table.
From the question, the metal is the limiting reactant and must be used to obtain the required results which are;
a) There are 1.20 mol F in MF2.
b) There are 40g of M in MF2.
c) M is calcium.
From the reaction equation;
M + F2 ----> MF2
Since the reaction is 1:1, 0.600 mol of MF2 is formed
Note that 1 mole of MF2 contains two moles of F and one mole of M
Hence, number of moles of F in MF2 = 2 * 0.600 mol = 1.20 mol F
Since 1 mole of M is contained in MF2, there are 0.600 moles of M in MF2.
If 1 mol of M forms 1 mole of MF2
And, 0.600 mol of M form 0.600 mol of MF2
Number of moles of MF2 = mass/molar mass
Number of moles of MF2 = 0.600 mol
Mass of MF2 formed = 46.8 g
Molar mass of MF2 = mass/Number of moles of MF2
Molar mass of MF2 = 46.8 g/0.600 mol
Molar mass of MF2 = 78 g/mol
Molar mass = Sum of Relative atomic mass of component atoms.
Hence;
78 = M + 2(19)
M = 78 - 2(19)
M = 40 g
The element must be calcium

Starting with 5.00 g barium chloride n hydrate yields 4.26 g of anhydrous barium chloride after heating. Determine the integer n.
Answer:
BaCl₂·(H₂O)₂
Explanation:
The reaction that takes place is:
BaCl₂·(H₂O)ₙ → BaCl₂ + nH₂OThe information given by the problem tells us that 5.00 g of reactant were consumed. Of those 5.00 g, 4.26 g were converted into BaCl₂, this means that the other 0.74 g were converted into water.
We convert 0.74 g of water into moles, using its molar mass:
0.74 g H₂O ÷ 18 g/mol = 0.041 mol H₂OThen we convert 4.26 g of BaCl₂ into moles:
4.26 g BaCl₂ ÷ 208.23 g/mol = 0.0204 mol BaCl₂We can write these results as (BaCl₂)₀.₀₂·(H₂O)₀.₀₄. We multiply those coefficients by 50 in order to make them integers, and we're left with:

Aqueous solutions of ionic compounds cause to dissociate, hence, ions are free to conduct electricity
Explanation:
Ionic compounds are compounds formed from ions (charged atoms). For example, NaCl is an ionic compound from the following ions; Na+ (cation) and Cl- (anion). One characteristics of ionic compounds is their ability to dissociate into the ions that form them when in an aqueous solution i.e. NaCl will dissociate into Na+ and Cl- when in an aqueous solution.
These disssociated ions are free to conduct electricity, hence, making ionic compounds good conductors of electricity.

A student connects a battery to a wire and wraps the wire around an iron nail to produce an electromagnet. Which action
should the student take to increase the number of paper clips the electromagnet can pick up?
He should replace the iron nail with a plastic spoon.
He should add another battery.
He should decrease the current through the wire
He should reduce the number of turns
Answer:
He should add another battery.
Explanation:
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a core of magnetic material usually an iron core. When an electric current-producing battery is connected to the wire, an electric current will begin to flow and the iron core will become magnetized. When the battery is disconnected, the iron core will lose its magnetism.
Electromagnets works based on the electromagnetic field which is a field force due to the interaction of the electric and magnetic fields. the force on the wire is proportional to the size of the current, the length and thickness of the iron core, as well as the number of turns of wire around the iron core.
Therefore, from the number of possible action given that the student can take in order to increase the magnetism of his electromagnet, adding another battery, thereby increasing the current will be the best way to increase the number of paper clips tat his electromagnet can pick up.
Answer:
they are correct he should add another battery trust me

Answer:
Both empirical and molecular are C₈H₈O₃.
Explanation:
Hello!
In this case, according the attached picture, it is possible to figure out the molecular formula of the mandelic acid by counting each carbon, hydrogen and oxygen in the molecule.
In such a way, we can see the presence of eight carbon atoms, eight hydrogen atoms and three carbon atoms; thus, the molecular formula is:
C₈H₈O₃
Furthermore, since the empirical formula is the smallest representation of the molecular formula when we are able to simplify it, we evidence no simplification is possible, consequently, the empirical formula equals the molecular one.
