Answer:
The equilibrium will shift to the right producing more Ag⁺ and CO₃²⁻
Explanation:
In the equilibrium:
Ag₂CO₃(s) ⇄ 2Ag⁺(aq) + CO₃²⁻(aq)
The change in concentration of Ag⁺ or CO₃²⁻ will shift the equilibrium
The addition of HCl(aq) (Dissociates in H⁺ and Cl⁻ ions) produce the formation of AgCl. The reaction is:
Ag⁺(aq) + Cl⁻(aq) ⇄ AgCl(s)
That means the addition of HCl decrease concentration of Ag⁺.
Based on LeChatelier's principle: As the Ag⁺ decreases, the equilibrium will decrease amount of Ag₂CO₃ producing more Ag⁺ and CO₃²⁻. That is:
The equilibrium will shift to the right producing more Ag⁺ and CO₃²⁻What mass of neon gas is required to fill a 5.00-L container to
a pressure of 1.02 atm at 25 °C?
Answer:
[tex]m=4.21g[/tex]
Explanation:
Hello,
In this case, by using the ideal gas equation:
[tex]PV=nRT[/tex]
We can compute the mass of neon gas at the given conditions by firstly computing the moles and also considering the temperature in kelvins (298K):
[tex]n=\frac{PV}{RT}=\frac{1.02atm*5.00L}{0.082\frac{atm*L}{mol*K}*298K}\\ \\n=0.209mol[/tex]
Finally, by using the atomic mass of neon gas (20.18g/mol) we compute the required mass to fill the 5.00-L container:
[tex]m=0.209mol*\frac{20.18g}{1mol}\\ \\m=4.21g[/tex]
Best regards.
The mass of neon gas will be "4.21 g".
Ideal Gas Equation:Given:
Pressure, P = 1.02 atmVolume, V = 5.00 LTemperature, T = 25°C or 298 KBy using Ideal Gas Equation,
⇒ [tex]PV = nRT[/tex]
or,
⇒ [tex]n = \frac{PV}{RT}[/tex]
By substituting the values,
[tex]= \frac{1.02\times 5.00}{0.082\times 298}[/tex]
[tex]= 0.209 \ mol[/tex]
hence,
The Mass will be:
= [tex]0.209\times \frac{20.18}{1}[/tex]
= [tex]4.21 \ g[/tex]
Thus the above answer is right.

How does accuracy and precision impact your life
Explanation:
Accuracy refers to the closeness of a measured value to a standard or known value. For example, if in lab you obtain a weight measurement of 3.2 kg for a given substance, but the actual or known weight is 10 kg, then your measurement is not accurate. In this case, your measurement is not close to the known value.
Precision refers to the closeness of two or more measurements to each other. Using the example above, if you weigh a given substance five times, and get 3.2 kg each time, then your measurement is very precise. Precision is independent of accuracy. You can be very precise but inaccurate, as described above. You can also be accurate but imprecise.
For example, if on average, your measurements for a given substance are close to the known value, but the measurements are far from each other, then you have accuracy without precision.
A good analogy for understanding accuracy and precision is to imagine a basketball player shooting baskets. If the player shoots with accuracy, his aim will always take the ball close to or into the basket. If the player shoots with precision, his aim will always take the ball to the same location which may or may not be close to the basket. A good player will be both accurate and precise by shooting the ball the same way each time and each time
A submarine took 9 hours to complete a journey. For the first 5 hours, it traveled at an average speed of 106km/h. For the rest of the journey, it traveled at an average speed of 125km/h. What was the total distance of the journey?
The correct answer is 1030 km
Explanation:
The distance a body such as a submarine travels depends on two main variables the time of the movement and the speed. Indeed, to calculate the distance it is possible to use the formula d = s x t. The process to calculate the distance of the submarine journey is shown below:
Distance in the first part of the journey:
It is known during the first part of the journey the submarine traveled 5 hours at a speed of 106 km/h
Distance = speed × time
D = 106 km/h × 5 h
D = 530 km
Distance in the second part of the journey:
During the remaining 4 hours (the first part took 5 hours and the total time traveled were 9 hours) the speed was 125km/h. Now, let's calculate the distance covered during this part of the journey
Distance = speed × time
D= 125 km/h × 4 h
D= 500 km
Total distance:
Finally, add both distances to know the total distance
530 km + 500 km = 1030 km
Express 2.99 x 108 m/s (the speed of light) in decimal notation (i.e., express the
number without using scientific notation
Answer:
speed of light = 299,000,000 m/s
Explanation:
The speed of light in vacuum, denoted as c, is a universal physical constant which unlike space and time, is independent of the observer. It is a constant that is important in many fields of science. Its exact value is given as 299,792,458 metres per second.
In scientific notation, it is approximately given as 2.99 x 10⁸ metres per second.
2.99 x 10⁸ metres per second = 2.99 x 100000000 = 299,000,000 m/s
Therefore, when expressed in decimal notation, the speed of light = 299,000,000 m/s.

Which of the following gases is the least soluble in water and why? CO2, SO3, N2, NH3, HCl.
Answer:
SO3
It has the highest molar mass value and thus would be the least soluble
Explanation:
In this question, we want to know which of the gases is the least soluble in water.
The easiest way to do this is to calculate the molar masses of these gases. The gas with the highest molar mass is the heaviest and thus will be the least soluble in water
For CO2 - molar mass is 44 g/mol
For SO3- molar mass is 80 g/mol
For N2- molar mass is 28g/mol
For NH3-molar mass is 17g/mol
For HCl- molar mass is 36.5 g/mol
From the molar masses, we can see that the molar mass of the ammonia gas is the lightest and thus, it is the most soluble.
The mass of the sulphur vi oxide is the highest and thus it is the heaviest and the least soluble in water
Which of the following are false about Prokaryotic Transcription termination?
A. It can occur in a factor dependent fashion.
B. It can occur in a factor independent fashion.
C. It may involve Rho protein.
D. none of the above.
Answer: none of the above
Explanation:
In Prokaryotic Transcription termination, it should be noted that the RNA polymerase transcribes through a terminator sequence, which in turn results in the polymerase to be separated from the DNA and thereby leads to its release of the transcrip.
Prokaryotic Transcription termination can occur in a factor dependent fashion, can occur in a factor independent fashion and may involve Rho protein.
Therefore, none of the options is false.

KCl is an ionic salt with a formula weight of 74.54 g/mole. A 1.417 M (mole/liter) KCl solution has a density of 1064.5 grams/liter at 20.0 OC. Use the Molarity and the formula weight to find the mass (g) of salt in one liter. Then, find the mass (g and kg) of water in one liter of the solution as the difference between the solution mass and the KCl mass. Include the conversion factor. Determine the molality (m), or moles of salt per kg of water, by dividing the moles of salt in one liter by the kg of water in one liter. Show all units and use proper significant figures. (
Answer:
Mass of the salt: 105.6g of KCl.
Mass water: 958.9g of water.
Molality: 1.478m.
Explanation:
Mass of the salt:
In 1L, there are 1.417 moles. In grams:
1.417 moles KCl * (74.54g / mol) = 105.6g of KCl
Mass of the water:
We can determine the mass of solution (Mass of water + mass KCl) by multiplication of the voluome (1L and density 1064.5g/L), thus:
1L * (1064.5g / L) = 1064.5g - Mass solution.
Mass water = 1064.5g - 105.6g = 958.9g of water
Molality:
Moles KCl = 1.417 moles KCl.
kg Water = 958.9g = 0.9589kg.
Molality = 1.417mol / 0.9589kg = 1.478m
