When the common ion effect is in action, the equilibrium of a system will shift to: Select the correct answer below:
a. decrease the amount of the common ion in the system
b. increase the amount of the common ion in the system
c. depends on the ion
d. The system will not shift at all.
Answer:
a. decrease the amount of the common ion in the system
Explanation:
The correct option is - a. decrease the amount of the common ion in the system
Reason -
Adding a common ion decreases solubility, as the reaction shifts toward the left to relieve the stress of the excess product.
Adding a common ion to a dissociation reaction causes the equilibrium to shift left, toward the reactants, causing precipitation.

molarity, chemistry general chemistry
Answer:
a. 0.026 M
Explanation:
Molarity is a measure of the molar concentration of a solution. It can be calculated by using the following formula:
Molarity = n/V
Where;
n = number of moles (mol)
V = Volume of solution (L)
Based on the information provided;
V = 23.2mL = 23.2/1000 = 0.0232 L
n = ?
To get the number of moles of KHP, we use the formula:
mole = mass/molar mass
mole (n) = 0.123/204.2
mole (n) = 0.0006024mol
Molarity = n/V
Molarity = 0.0006024 ÷ 0.0232
Molarity = 6.024 × 10^-4 ÷ 2.32 × 10^-2
Molarity = 6.024/2.32 × 10^(-4--2)
Molarity = 2.59 × 10^-2
Molarity = 0.026 M

Balanced equation: K2S(aq) + BaCl2(aq) =
Answer:
K2S(aq) + BaCl2(aq) = 2KCl(aq) + BaS(s)
In the image attached, it is explained how the solution is balanced.
The number of atoms of any element in the given chemical formula is the number that is written on the foot of the symbol of that element. The balanced equation is
K[tex]_2[/tex]S(aq) + BaCl[tex]_2[/tex](aq)[tex]\rightarrow[/tex]2KCl(aq) + BaS(s)
What is Balanced equation?Balanced equation is the one in which the total number of atoms of a species on reactant side is equal to the total number of atoms on product side.
The unbalanced equation is
K[tex]_2[/tex]S(aq) + BaCl[tex]_2[/tex](aq) [tex]\rightarrow[/tex]KCl(aq) + BaS(s)
The number of atoms of K on reactant side is 2 while on product side it is 1, so to balance K we need to multiply KCl by 2
K[tex]_2[/tex]S(aq) + BaCl[tex]_2[/tex](aq) [tex]\rightarrow[/tex]2KCl(aq) + BaS(s)
The atoms of sulfur on reactant and product side is 1, so it is balanced.
The atoms of Ba on reactant and product side is 1, so it is balanced.
The atoms of Cl on reactant and product side is 2, so it is balanced.
Therefore the balanced equation is
K[tex]_2[/tex]S(aq) + BaCl[tex]_2[/tex](aq)[tex]\rightarrow[/tex]2KCl(aq) + BaS(s)

How many grams would be in 4.45 x 10^23 molecules of N203
Answer:
56.24g
Explanation:
To find the mass of N2O3 in 4.45 x 10^23 molecules, it must first be converted to moles by dividing the number of molecules in N2O3 by Avagadro's number (6.02 × 10^23).
number of moles in N2O3 = 4.45 x 10^23 ÷ 6.02 × 10^23
n = 4.45/6.02 × 10^(23 - 23)
n = 0.74 × 10^0
n = 0.74moles.
Using the formula below to find the mass of N2O3;
mole = mass ÷ molar mass
Molar mass of N2O3 = 14(2) + 16(3)
= 28 + 48
= 76g/mol
mass = mole × molar mass
Mass = 0.74 × 76
Mass = 56.24g

(The gas constant is

mol K
)
Round your answer to one decimal place and enter the number only with no units.
Your Answer:
Answer
Answer:
1.0 mole
Explanation:
From the question given above, the following data were obtained:
Volume (V) = 5 L
Temperature (T) = 205 K
Pressure (P) = 340 KPa
Gas constant (R) = 8.31 KPa.L/Kmol
Number of mole (n) =?
Using the ideal gas equation, the number of mole of the gas in the container can be obtained as follow:
PV = nRT
340 × 5 = n × 8.31 × 205
1700 = n × 1703.55
Divide both side by 1703.55
n = 1700 / 1703.55
n = 1.0 mole
Thus, the number of mole of the gas in the container is 1.0 mole
If water was used to rinse the burette used to dispense the hydrochloric acid solution, how would this affect
your final estimate of hydrochloric acid concentration? (More, less or unchanged?) Explain why, discussing
the number of moles that you would actually have due to the rinsing.
Answer:
The concentration of hydrochloric acid would be estimated to be less.
Explanation:
This is because, the hydroxyl ions from water react with the hydrogen ions from the hydrochloric acid, hence decreasing the moles of hydrogen ions which lowers the acidic strength of Hydrochloric acid.
If water was used to rinse the burette and the burette is then used to dispense hydrochloric acid solution, the final estimate of hydrochloric acid concentration will be less.
It is usual to rinse the burette with the solution that ought to be in it after rinsing it with water.
However, in this case, the burette was was rinsed with water alone and then it was used to dispense the hydrochloric acid solution.
The water will dilute the hydrochloric acid solution thereby making the final estimate of hydrochloric acid concentration to be less.
Hence, if water was used to rinse the burette used to dispense the hydrochloric acid solution, the final estimate of hydrochloric acid concentration will be less.

Which of the following phrases best describes a scientist?
A person who learns about the world by observing it
A person who is highly educated
A person who understands how the world behaves
A person who is extremely knowledgeable about the world
Answer:
A
Explanation:
A scientist is a person who conducts scientific research to advance knowledge in an area of interest.
HistoryIn classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. It was not until the 19th century that the term scientist came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833.

KCI: 74.55 g/mol
LiCl: 42.39 g/mol
Answer:
[tex]n_{tot}=0.652mol[/tex]
Explanation:
Hello there!
In this case, according to the given problem, it is possible to use the given molar masses of NaCl, KCl and LiCl in order to calculate the total moles, yet we calculate the moles of each salt first as shown below:
[tex]n_{NaCl}=21.7gNaCl*\frac{1molNaCl}{58.44gNaCl}=0.371molNaCl\\\\ n_{KCl}=3.74gKCl*\frac{1molKCl}{74.55KCl}=0.0502molNaCl\\\\ n_{LiCl}=9.76gLiCl*\frac{1molLiCl}{42.39gLiCl}=0.230molLiCl[/tex]
Then, we add them all together to obtain:
[tex]n_{tot}=0.371mol+0.0502mol+0.230mol\\\\n_{tot}=0.652mol[/tex]

In the 1990s scientists were studying the comet named Shoemaker-Levy. Write a short report about this comet.
Answer:
Please find the report on the comet below
Explanation:
Specifically in the year 1993, a comet was discovered by three individuals namely: Eugene Shoemaker, Carolyn Shoemaker, and David Levy. The comet was named after the first discoverers as; Shoemaker-Levy 9.
Shoemaker-Levy 9 was reported to have already been in pieces as at the time of discovery. It was believed to have been torn apart by the gravitational force emanating from the biggest of the planets called JUPITER.
In July 1994, Shoemaker-Levy 9 came in contact with Jupiter in what seemed to be the end of the discovered comet. This collision of Shoemaker-Levy 9 with planet Jupiter was said to be the first ever solar systems collision observed.

c) water expands whenit freezes and does not damagethecell wall.
d) water contracts when it freezes and does not damagethecell wall.
e) water does not change in size whenit freezes.
Answer:
a) water expands when it freezes and damages the cell wall.
Explanation:
We know that most liquids expand when heated and contract when cooled. Water does not behave in the same way.
Water contracts on cooling from any temperature until 4°C when it begins to expand until 0°C. Hence a given mass of water has its least volume and highest density at 4°C.
Hence, fresh vegetables with high water content do not freeze well because water expands when it freezes and damages the cell wall.
