The statement in which La Niña affect the climate of the Pacific Ocean is "The cold water sinks deeper into the ocean."
What is La Niña effect?La Niña is a climate phenomenon that depicts the cooling of surface ocean waters along the coast of South America's tropical west coast.
What is climateThe average weather in a certain place over a longer length of time is referred to as climate.
The jet stream moves northward and weakens across the eastern Pacific as a result of La Niña. The South experiences warmer and drier weather than usual during La Nia winters. The North and Canada are wetter and colder than the rest of the country. The seas off the Pacific coast are cooler and contain more nutrients than typical during La Niña.
Water in the eastern Pacific is colder than typical because to La Niña. El Niño might cause the water to be warmer than usual in the same place. During La Niña years, drought-stricken areas are drenched, while El Niño years are drenched.
Hence the correct option is 2.

-- A scientist combines 14 grams of potassium nitrate with an unknown amount of
potasslum chloride. If the total mass of the products is 27.6 grams, what was the
mass of the potassium chloride?
Cada
Answer:
The unknown amount of potassium chloride is 13.6 grams.
Explanation:
The reaction of 14 grams of KNO₃ with KCl produces a total mass of 27.6 grams of the products.
The law of conservation of mass tells us that the total mass of the reactants must be the same that the total mass of the products. So, we can find the mass of KCl as follows:
[tex] m_{r} = m_{p} [/tex]
Where r is for reactants and p is for products
[tex] m_{KNO_{3}} + m_{KCl} = m_{p} [/tex]
[tex] 14 g + m_{KCl} = 27.6 g [/tex]
[tex] m_{KCl} = 27.6 g - 14 g = 13.6 g [/tex]
Therefore, the unknown amount of potassium chloride is 13.6 grams.

The equivalence point for a strong acid – strong base titration will occur at:
pH < 7
pH = 7
pH > 7
pH = 14
I believe the ans is (2) pH = 7.
Explanation:
At the equivalence point, the salt of strong acid and strong base is completely hydrolyzed which gives a neutral solution with pH 7 as H+ ion concentration is equal to OH- ion concentration.

How many moles of CaF2 will form from 36 moles of AlF3?
Answer:
54 moles
Explanation:
The ratio of AIF3 to CaF2 is, as seen in the equation, 2:3. This means you multiply 36 moles by 3, and then divide it by 2. This equals 54 moles of CaF2.

How many grams of chlorine would exert a pressure of 610 torr in a 3.26-liter container at standard temperature? 4.25gCL
Answer:
[tex]m=8.28gCl_2[/tex]
Explanation:
Hello there!
In this case, according to the given information, it possible for us to realize that this problem is solved via the ideal gas equation:
[tex]PV=nRT[/tex]
By which we solve for the moles of chlorine gas as shown below:
[tex]n=\frac{PV}{RT}[/tex]
Next, we plug in the given pressure (in atm), the volume and standard pressure (273.15K) to obtain:
[tex]n=\frac{610/760atm*3.26L}{0.08206\frac{atm*L}{mol*K}*273.15K}\\\\n=0.117molCl_2[/tex]
Then, since the molar mass of chlorine gas (Cl2) is 70.9 g/mol, the mass of this gas turns out to be:
[tex]m=0.117molCl_2*\frac{70.9gCl_2}{1molCl_2} \\\\m=8.28gCl_2[/tex]

When 9.20 moles of carbon dioxide are produced from the reaction above, how many moles of Iron(III) Oxide must have been present before the reaction took place?
Answer:
3.1 moles of Iron(III) Oxide
Explanation:
The equation of the reduction of iron III oxide using carbon is shown;
Fe2O3 + 3CO → 2Fe + 3CO2
From the reaction equation;
1 mole of Iron(III) Oxide yielded 3 moles of carbon dioxide
x moles of Iron(III) Oxide will yield 9.20 moles of carbon dioxide
x = 9.2 moles * 1 mole/3 moles
x = 3.1 moles of Iron(III) Oxide

1. What did you notice about the distance between the atoms as the number of bonds increased? (Compare bond of H2S and H2O)
2. What is the relationship between atomic size and bond length for H2O / H2S and CO2 / CS2?
Answer:
Inverse relationship between number of covalent bonds and bond length.
Explanation:
There is inverse relationship between number of covalent bonds and bond length which means that if one increases the decreases or the one decreases the increases. When the number of covalent bonds between two atoms increases, the bond length decreases because there are more number of electrons present between the two nuclei, the two nuclei can get closer to each other until both nuclei experience their repulsive force of attraction. In bond of H2S has lower electronegativity value as compared to H2O so the bond length decreases due to attraction of shared pair of electrons by both nuclei.

How is primary selection different from secondary succession?
Answer:
Explanation:
Primary and secondary succession occur after both human and natural events that cause drastic change in the makeup of an area. Primary succession occurs in areas where there is no soil and secondary succession occurs in areas where there is soil.
In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area previously occupied by living things is disturbed—disrupted—then recolonized following the disturbance.
