What mass of reactant remains if 27 g of al is allowed to react with 213 g of cl2?
Answers
If 27 g of Al is allowed to react with 213 g of Cl2, approximately 177.25 g of Cl2 remains unreacted.
To determine the mass of reactant remaining, we need to identify the limiting reactant in the given reaction. The limiting reactant is the reactant that is completely consumed and determines the maximum amount of product that can be formed.
Let's first write the balanced equation for the reaction between aluminum (Al) and chlorine (Cl2):
2Al + 3Cl2 → 2AlCl3
From the balanced equation, we can see that 2 moles of aluminum react with 3 moles of chlorine to produce 2 moles of aluminum chloride.
Next, we calculate the number of moles for each reactant:
Moles of Al = mass of Al / molar mass of Al
Moles of Cl2 = mass of Cl2 / molar mass of Cl2
Molar mass of Al = 26.98 g/mol
Molar mass of Cl2 = 70.90 g/mol
Moles of Al = 27 g / 26.98 g/mol ≈ 1.00 mol
Moles of Cl2 = 213 g / 70.90 g/mol ≈ 3.00 mol
According to the balanced equation, the stoichiometric ratio between Al and Cl2 is 2:3. This means that for every 2 moles of Al, we need 3 moles of Cl2 for complete reaction.
Since we have more than enough moles of Cl2 (3.00 mol) compared to the moles of Al (1.00 mol), aluminum is the limiting reactant.
To calculate the mass of reactant remaining, we need to determine the moles of excess Cl2 remaining after the reaction with Al. We subtract the moles of Cl2 used in the reaction from the initial moles of Cl2:
Moles of excess Cl2 = Moles of Cl2 - Moles of Cl2 used in the reaction
Moles of excess Cl2 = 3.00 mol - (1.00 mol / 2 * 3/2)
Moles of excess Cl2 = 3.00 mol - 0.50 mol = 2.50 mol
Now, we can calculate the mass of excess Cl2 remaining:
Mass of excess Cl2 = Moles of excess Cl2 * Molar mass of Cl2
Mass of excess Cl2 = 2.50 mol * 70.90 g/mol ≈ 177.25 g
Therefore, if 27 g of Al is allowed to react with 213 g of Cl2, approximately 177.25 g of Cl2 remains unreacted.

The partial pressure of N2 in a mixture of gases, where the total pressure is 1.50 atm, is 300. torr. What is the mole fraction of N2
Answers
Answer:
The mole fraction of N₂ is 0.26.
Explanation:
The pressure exerted by a particular gas in a mixture is known as its partial pressure. So, Dalton's law states that the total pressure of a gas mixture is equal to the sum of the pressures that each gas would exert if it were alone:
PT = PA + PB
This relationship is due to the assumption that there are no attractive forces between the gases.
Dalton's partial pressure law can also be expressed in terms of the mole fraction of the gas in the mixture. The mole fraction is a dimensionless quantity that expresses the ratio of the number of moles of a component to the number of moles of all the components present.
So in a mixture of two or more gases, the partial pressure of gas A can be expressed as:
PA = XA * PT
In this case:
PA= PN₂= 300 torrXA=XN₂= ?PT= 1.50 atm= 1140 torr (being 1 atm= 760 torr)Replacing:
300 torr= XN₂*1140 torr
Solving:
\(X_{N_{2} } =\frac{300 torr}{1140 torr}\)
XN₂= 0.26
The mole fraction of N₂ is 0.26.

Answers
To find the lower quartile (Q1) and upper quartile (Q3) of the given data set, we first determine the median, which is the middle value. Since there are 10 observations, the median is the value at the 5th position, which is 490.
To calculate Q1, we find the median of the lower half of the data set, which consists of 238, 483, 487, 488, and 489. The median of this subset is the lower quartile, resulting in Q1 = 487.
The interquartile range (IQR) is the difference between Q3 and Q1. Substituting the values, we have IQR = 507 - 487 = 20.
To calculate the lower boundary, we use the formula Q1 - 1.5 * IQR. Plugging in the values, we get LB = 487 - 1.5 * 20 = 457.
Similarly, the upper boundary is calculated as Q3 + 1.5 * IQR. Substituting the values, we find UB = 507 + 1.5 * 20 = 537.
An observation is considered an outlier if it falls below the lower boundary (457) or above the upper boundary (537).

Identify 2 possible sources of random (indeterminate) error. Identify 2 possible sourses of systematic (determinate) error.
Answers
Two possible sources of systematic (determinate) error in the experiment are; Incorrect calibration of volumetric glasswareIncorrect mass of NaCl
To calculate the concentration of NaCl in the resulting solution in mg/L NaCl, we can use the formula; Concentration (mg/L) = (Mass of solute ÷ Volume of solution in L) × 1000 g / 1 mg NaCl is present in the stock solution of 25 mL. So, the mass of NaCl in the solution would be;0.0842 g ÷ 25 mL = 0.00337 g/mL. Now, in the resulting solution, a 1.00 mL aliquot of the stock solution is transferred to a 50.00 mL volumetric flask and diluted to volume. Therefore, the volume of the resulting solution is 50.00 mL. We will substitute these values in the formula, Concentration (mg/L) = (0.00337 g/mL ÷ 50 mL) × 1000 g / 1 mg concentration (mg/L) = 67.4 mg/L. Therefore, the concentration of NaCl in the resulting solution in mg/L NaCl is 67.4 mg/L.7. Concentration = 67.4 mg/LTolerance = 4.28 mg/LTotal concentration = 67.4 + 4.28 mg/L = 71.68 mg/LWe round off this value to one decimal place; Total concentration = 71.7 mg/LTherefore, the concentration of NaCl in the resulting solution using propagation of error through the calculation is 67.4+0.4 mg/L.8. Two possible sources of random (indeterminate) error in the experiment are; Errors in temperature measurement. Errors in measurement of water volume.

The molar solubility for magnesium carbonate is 1.8 x 10-4 mol/Lwhat is the Ksp for this compound
Answers
The molar solubility for magnesium carbonate is 1.8 x 10-4 mol/ p09the solubility product constant (Ksp) for magnesium carbonate (MgCO3) is 3.24 x 10^-8.
To determine the solubility product constant (Ksp) for magnesium carbonate (MgCO3), we need to set up the balanced chemical equation for its dissolution and use the molar solubility value provided.
The balanced equation for the dissolution of magnesium carbonate is:
MgCO3(s) ⇌ Mg2+(aq) + CO3^2-(aq)
The equilibrium expression for the solubility product constant is:
Ksp = [Mg2+][CO3^2-]
From the balanced equation, we can see that the concentration of magnesium ions ([Mg2+]) is equal to the molar solubility (1.8 x 10^-4 mol/L), and the concentration of carbonate ions ([CO3^2-]) is also equal to the molar solubility (1.8 x 10^-4 mol/L).
Substituting the values into the equilibrium expression, we have:
Ksp = (1.8 x 10^-4)(1.8 x 10^-4)
Calculating this expression gives us:
Ksp = 3.24 x 10^-8
Therefore, the solubility product constant (Ksp) for magnesium carbonate (MgCO3) is 3.24 x 10^-8.

Cylinder B contains molecules that are moving more slowly than the molecules in Cylinder A. Cylinder B contains a gas that has a temperature closest to absolute zero.
Answers
Answer:
The correct option is;
Cylinder A contains a gas that has a temperature closest to absolute zero
Explanation:
From the kinetic theory of gases, the average speed of a gaseous molecule is found from the following equation;
\(v_{rms} = \sqrt{\frac{3\cdot R \cdot T}{MW} }\)
Where:
\(v_{rms}\) = rms speed which is the square root of the average of the velocities of the gas molecules squared which is used in place of the average of the gas molecules as the sum of the velocities of all the gas molecules in the cylinder is zero
R = Universal gas constant = 8.3145 J/(mol·K)
MW = Molecular weight of the gas
Hence where we have;
\(v_{rmsA}\) = Average velocity of gas A = 0.0000001 m/s
\(v_{rmsB}\) = Average velocity of gas B = 0.3 m/s
Since, R and MW are constant for the gas in cylinder A constant, therefore, as \(v_{rmsA}\) ≈ 0 m/s, the temperature, \(T_A\), of gas A is closest to absolute zero.

CFCs were widely used in various industrial applications, including aerosol propellants, refrigerants, foam-blowing agents, and solvents. However, their production and use have significantly declined due to their harmful environmental impacts.
In terms of climate change, CFCs are potent greenhouse gases that have a much higher global warming potential (GWP) than carbon dioxide (CO2). The GWP is a measure of how much heat a greenhouse gas traps in the atmosphere over a specific time period compared to CO2. CFCs can trap a substantially greater amount of heat per unit mass compared to CO2, making them particularly effective at contributing to global warming.
It's important to note that CFCs not only have a high GWP but also deplete the ozone layer in the stratosphere. Their release into the atmosphere has been linked to the destruction of ozone molecules, leading to the formation of the ozone hole.
Due to their detrimental effects on both climate change and ozone depletion, international agreements such as the Montreal Protocol have been established to regulate and phase out the production and use of CFCs and other ozone-depleting substances.
In summary, CFCs can be classified as halocarbons, synthetic organic compounds containing carbon, chlorine, and fluorine. They are potent greenhouse gases with a high global warming potential and contribute to ozone depletion in the stratosphere.
