Describe the region(s) of the Atlantic Oceans where dense waters will likely sink/
Answer:
The densest ocean water is formed in two primary locations near the poles, where the water is very cold and highly saline as a result of ice formation. The densest deep water mass is formed in the Weddell Sea of Antarctica, and becomes the Antarctic Bottom Water (AABW).
Explanation:
The densest ocean water is formed in two primary locations near the poles, where the water is very cold and highly saline as a result of ice formation. The densest deep water mass is formed in the Weddell Sea of Antarctica, and becomes the Antarctic Bottom Water (AABW).
Density is an intensive property as it does not depend on the quantity of the substances Whereas mass and volume are extensive property. Therefore, north Atlantic Ocean is the region of Atlantic Oceans where dense waters will likely sink.
What is density?Density tells about the compactness of the substances, how much dense is the substances in other words. Object that is more denser than water they just sink in the water.
Mathematically,
Density = Mass of the metal ball ÷volume marked on the graduated cylinder
North Atlantic Ocean is the region of Atlantic Oceans where dense waters will likely sink. Here, water is very cold and salty which makes the water denser.
Therefore, north Atlantic Ocean is the region of Atlantic Oceans where dense waters will likely sink.

what is the function of a prism
Answer:
Prisms are sometimes used for the internal reflection at the surfaces rather than for dispersion. If light inside the prism hits one of the surfaces at a sufficiently steep angle, total internal reflection occurs and all of the light is reflected.
Explanation:
Prism, in optics, piece of glass or other transparent material cut with precise angles and plane faces, useful for analyzing and reflecting light. An ordinary triangular prism can separate white light into its constituent colours, called a spectrum.

Calculate the pH during the titration of 20.00 mL of 0.1000 M HNO2(aq) with 0.1000 M KOH(aq) after 13.27 mL of the base have been added. Ka of nitrous acid = 7.1 x 10-4.
Answer:
pH = 2.462.
Explanation:
Hello there!
In this case, according to the reaction between nitrous acid and potassium hydroxide:
[tex]HNO_2+KOH\rightarrow KNO_2+H_2O[/tex]
It is possible to compute the moles of each reactant given their concentrations and volumes:
[tex]n_{HNO_2}=0.02000L*0.1000mol/L=2.000x10^{-3}mol\\\\n_{KOH}=0.1000mol/L*0.01327L=1.327x10^{-3}mol[/tex]
Thus, the resulting moles of nitrous acid after the reaction are:
[tex]n_{HNO_2}=2.000x10^{-3}mol-1.327x10^{-3}mol=6.73x10^{-4}mol[/tex]
So the resulting concentration considering the final volume (20.00mL+13.27mL) is:
[tex][HNO_2]=\frac{6.73x10^{-4}mol}{0.01327L+0.02000L} =0.02023M[/tex]
In such a way, we can write the ionization of this weak acid to obtain:
[tex]HNO_2+H_2O\rightleftharpoons NO_2^-+H_3O^+[/tex]
So we can set up its equilibrium expression to obtain x as the concentration of H3O+:
[tex]Ka=\frac{[NO_2^-][H_3O^+]}{[HNO_2]}\\\\7.1x10^{-4}=\frac{x^2}{0.02023M-x}[/tex]
Next, by solving for the two roots of x, we get:
[tex]x_1=-0.004161M\\\\x_2=0.003451M[/tex]
Whereas the correct value is 0.003451 M. Finally, we compute the resulting pH:
[tex]pH=-log(0.003451)\\\\pH=2.462[/tex]

What is the total number of grams of solute in 500 milliliters of 1M CH3COOH (formula mass = 60)?
Answer:
30 grams
Explanation:
Molarity of a solution represents its molar concentration, and can be calculated by using the formula as follows:
Molarity (M) = number of moles (n) ÷ volume (V)
Based on the information provided, volume of solution = 500 milliliters, molarity = 1M
Volume of solution in liters = 500mL ÷ 1000 = 0.50L
Molarity = n/V
1 = n/0.50
n = 0.50moles
Using mole = mass/molar mass
Molar mass of CH3COOH (acetic acid) = 60g/mol
Mass = mole × molar mass
mass = 0.50 × 60
mass = 30 grams.

Many ski resorts and mountain cities can be reached directly by planes which deposit travelers a mile or more above sea level. This can result in altitude sickness due to hypoxemia, or reduced oxygen in the blood, caused by the unaccustomed exposure to the lower atmospheric pressure at high elevations. On a given day, the prevailing atmospheric pressure in Albuquerque, NM (elevation 1620 meters) might be 0.799 atm. Calculate this pressure expressed in mmHg and in torr. Relationship between altitude and barometric pressure.
Answer:
See explanation
Explanation:
To convert from atm to mmHg
1 atm = 760 mmHg
0.799 atm = 0.799 atm * 760 mmHg/1 atm = 607.24 mmHg
To convert from atm to torr
1 atm = 760 torr
0.799 atm = 0.799 atm * 760 torr/1 atm = 607.24 torr

For which of the reactions listed below will Gibbs free energy always be.
positive?
O A. An exothermic reaction that decreases in entropy
B. An exothermic reaction that increases in entropy
O C. An endothermic reaction that decreases in entropy
D. An endothermic reaction that increases in entropy
I think the answer is: C. An endothermic reaction that decreases in entropy
An endothermic reaction that decreases in entropy. Hence, option C is correct.
What is entropy?Entropy is the energy of a system that is unuseful to do work.
For a reaction to be spontaneous, the Gibbs' Free Energy must be negative.
The equation for Gibbs Free energy is given by:
G= H-TS
Where, G = Gibbs free energy
H = Enthalpy of the reaction
T = Temperature of the system
S = Entropy of the system
Sign convention for all the quantities:
For H: It is negative for exothermic reactions and positive for endothermic reactions
For S: It is positive when there is an increase in entropy and it is negative when there is a decrease in entropy.
If we want G to be negative, the conditions necessary are:
G= (-ve) - (+ve) = -ve
The product of temperature and entropy must be positive and that will be positive when there is increase in entropy at any temperature.
Hence, option C is correct.

[tex]\boxed {\boxed {\sf Cobalt, Iron, and \ Copper}}[/tex]
Explanation:
The Stock System states that In a chemical formula or equation, some metals need a roman numeral after their symbol. If a metal has multiple oxidation states, it needs a roman numeral.
Use the Periodic Table to see the oxidation states for each metal.
Cobalt (Co): +3, +2 Lithium (Li): +1 Barium (Ba): +2 Iron (Fe): +3, +2 Copper (Cu): +2, +1 Potassium (K): +1We can see that cobalt, iron, and copper have more than one oxidation state, so they would require a roman numeral.

Answer:
when dissolved in water they dissociate in anion and H+ cation.
Explanation:
When dissolved in water, acids donate hydrogen ions (H+). Hydrogen ions are hydrogen atoms that have lost an electron and now have just a proton, giving them a positive electrical charge. Bases, on the other hand, mixed with water yield hydroxide ions (OH-).
1. How many liters of a 0.50 M solution are needed to give 3.5 moles of solute?
Answer:
The volume of solution in liters required to make a 0.250 M solution from 3.52 moles of solute is 14.08 liters of solution
Explanation:
The question relates to the definition of the concentration of a solution which is the number of moles per liter (1 liter = 1 dm³) of solution
Therefore we have;
The concentration of the intended solution = 0.250 M
Therefore, the number of moles per liter of the required resolution = 0.250 moles
Therefore, the concentration of the required solution = 0.250 moles/liter
The volume in liters of the required solution that will have 3.52 moles of the solute is given as follows;
The required volume of solution = The number of moles of the solute/(The concentration of the solution)
∴ The required volume of solution = 3.52 moles/(0.250 moles/liter) = 14.08 liters
The required volume of solution to make a 0.250 M solution from 3.52 moles of solute = 14.08 liters.
Therefore the number of liters required to make a 0.250 M solution from 3.52 moles of solute = 14.08 liters.

What is the diameter of Neptune in standard notation and scientific notion?
Answer:
Standard notation: 49,244 km
Scientific notation: 4.92x10⁴ km
Explanation:
The diameter of Neptune in standard notation is:
49,244 km
In the standard notation, we write the result in a normal way.
Now, to express the diameter in scientific notation we need to use a base ten power as follows:
4.92x10⁴ km
In the above result, the positive exponent indicates that the number is larger. The decimal point is located near the first digit.
Therefore, the diameter of Neptune in standard notation is 49,244 km and in scientific notation is 4.92x10⁴ km.
