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.

Determine the number of molecules of OF2 and moles of fluorine contained in 5.53 moles of OF2.
Answer: [tex]33.31\times 10^{23}[/tex] molecules of [tex]OF_2[/tex]
and 11.06 moles of Flourine
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.
1 mole of [tex]OF_2[/tex] contains= [tex]6.022\times 10^{23}[/tex] molecules of [tex]OF_2[/tex]
Thus 5.53 moles of [tex]OF_2[/tex] contains=[tex]\frac{6.022\times 10^{23}}{1}\times 5.53=33.31\times 10^{23}[/tex] molecules of [tex]OF_2[/tex]

A student adds an alka-seltzer to the Koolaid and stirs. The pH meter now reads 8.3. What was released by the alka-seltzer tablet to cause this change?
Answer:
It released hydroxide ions (OH ¯).
Explanation:
A PH of 8.3 indicates that the solution has become a basic solution.
Now, for us to have a basic solution from the addition of an alka-seltzer to Koolaid, it means the Alka-seltzer released plenty of hydroxide ons (OH¯) to the solution.

What volume of 0.130 M HCl is required for the complete neutralization of 1.30 g of NaHCO3 (sodium bicarbonate)?
Answer: Volume required is 0.115 L or 115 ml
Explanation:
moles of [tex]NaHCO_3[/tex] = [tex]\frac{\text {given mass}}{\text {Molar mass}}=\frac{1.30g}{84g/mol}=0.015mol[/tex]
The balanced chemical equation is:
[tex]HCl+NaHCO_3\rightarrow NaCl+H_2CO_3[/tex]
1 mole of [tex]NaHCO_3[/tex] requires = 1 mole of HCl
Thus 0.015 mol of [tex]NaHCO_3[/tex] requires = [tex]\frac{1}{1}\times 0.015=0.015[/tex] mole of HCl
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

Imagine blowing up a latex balloon. Assume that you tie the balloon to prevent air from escaping and then squeeze the balloon with one hand, so there is less space inside it. Then assume you use both hands (and maybe a friend’s hands) to squeeze the balloon so there is even less space inside. What do you think will happen to the balloon if you keep squeezing it to a smaller and smaller volume? Explain your prediction.
Answer:
Balloon will burst
Explanation:
The amount of volume that can be held by the latex will reduce yet the volume of air inside does not change. therefore the air inside will force the latex to break.
Assume that you tie the balloon to prevent air from escaping and then squeeze the balloon with one hand, so there is less space inside it then balloon will burst.
What is latex balloon?
latex is what latex balloons are made of. Due to tiny microscopic holes in the latex, it is porous and does not hold helium for as long as foil balloons (mylar balloons).
While latex balloons usually float for only 8–24 hours, foil balloons typically float for 4–21 days. But you can actually get a latex balloon to float longer than a foil balloon by using a product called hi-float, which extends the life of a latex balloon by 25 times the average float time.
In addition to being available in a variety of colors and prints in sizes ranging from 5" to 3 feet, latex balloons can also be printed in many colors, however if you want a detailed design you really need to use foil balloons.
Therefore, Assume that you tie the balloon to prevent air from escaping and then squeeze the balloon with one hand, so there is less space inside it then balloon will burst.

After the reaction mixture is added to the top of the silica gel column, the instructions state: "Open the stopcock and drain the column until the meniscus is just above the top layer of the material. Add another 0.5 mL of solvent and repeat the process toensure that all of the desired products are adsorbed onto the silica gel. This process ensures that none of the desired products are dissolved in solution above the column."Why is this procedure important? How would the TLC plates look different than your prediction in Q1 if a student skipped this step?
Answer:
Kindly check the explanation section.
Explanation:
Without mincing words let's dive straight into the solution to the question.
The instructions given in the question above is very important as it concerns the total adsorption of the product on the silica gel. The instruction is made so that adsorption of the product is on the silica gel so as to avoid the distortion in polarity of the compound.
Part B.
If the student avoid the step, there would be problem of which the compound which is in mixture will be running out of the column. Also, the compounds won't be made pure.
In summary, for the first part adsorption is done on the silica gel thus, the instructions is to be followed.
For the second part, if the step is not avoided then the Compounds will be made pure if the step

Answer:
The options are unclear, however, the correct option is:
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.

Explanation:
The mechanism involves SN1 nucleophilic substitution reaction. The -OH group of the alcohol is first protonated. Since water is a good leaving group, -OH2 leaves the substrate creating a primary carbo cation.
A 1,2 methyl shift now occurs to create a tertiary carbo cation which is more stable leading to the major product shown in the image attached to this answer.
Calculate the number of moles of H2SO4 required to react with 0.93 moles of Al. Do not include units in your answer. Round to the tenths place or further.
Answer:
1.40 moles of H₂SO₄.
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below below:
2Al + 3H₂SO₄ —> Al₂(SO₄)₃ + 3H₂
From the balanced equation above,
2 moles of Al reacted with 3 moles of H₂SO₄.
Finally, we shall determine the number of mole of H₂SO₄ required to react with
0.93 moles of Al. This can be obtained as follow:
From the balanced equation above,
2 moles of Al reacted with 3 moles of H₂SO₄.
Therefore, 0.93 moles of Al will react with = (0.93 × 3)/2 = 1.40 moles of H₂SO₄.
Thus, 1.40 moles of H₂SO₄ is needed for the reaction.

How many grams of CaO can be produced using 3.9 moles CaCO3?1
CaCO3 --> 1CaO + 1CO *
Answer: 218.4 g of [tex]CaO[/tex] will be produced from 3.9 moles of [tex]CaCO_3[/tex]
Explanation:
The balanced chemical equation is:
[tex]CaCO_3\rightarrow CaO+CO_2[/tex]
According to stoichiometry :
1 mole of [tex]CaCO_3[/tex] produce = 1 mole of [tex]CaO[/tex]
Thus 3.9 moles of [tex]CaCO_3[/tex] will produce=[tex]\frac{1}{1}\times 3.9=3.9moles[/tex] of [tex]CaO[/tex]
Mass of [tex]CaO=moles\times {\text {Molar mass}}=3.9moles\times 56g/mol=218.4g[/tex]
Thus 218.4 g of [tex]CaO[/tex] will be produced from 3.9 moles of [tex]CaCO_3[/tex]
218.4 grams of CaO is produced using 3.9 moles CaCO₃.
How we calculate weight of any substance from moles?Moles of any substance will be define as:
n = W / M
Given chemical reaction is:
CaCO₃ → CaO + CO₂
From the above equation it is clear that according to the concept of stoichiometry 1 mole of CaCO₃ is producing 1 mole of CaO. By using above formula we calculate grams as follow:
W = n × M, where
n = no. of moles of CaO = 3.9 moles
M = molar mass of CaO = 56 g/mole
W = 3.9 × 56 = 218.4 g
Hence, 218.4 grams of CaO is produced.
