The correct balanced chemical equation is FeCl₃(aq) + Na₂S(aq) → 3Fe₂S₃(s) + 3NaCl(aq)

To achieve a chemical equation's balance:

Fe₂S₃ (s) + NaCl (aq) FeCl₃ (aq) + Na₂2S (aq)

Let's start by balancing the atoms of iron (Fe). The iron atoms are already balanced, since there are two on the reactant side and two on the product side.

Let's now balance the atoms of sodium (Na). Two sodium atoms are present on the reactant side, hence two sodium atoms are required on the product side. By adding a coefficient of 2 in front of NaCl, we may do this:

Let's balance the sulfur (S) atoms lastly.

The acid derivative in each pair that undergoes hydrolysis more quickly can be determined by looking at the steric hindrance of the carbonyl carbon. Pair A: Ethyl benzoate vs. methyl benzoate and Pair B: N-propyl acetate vs. isopropyl acetate.

The greater the steric hindrance, then it slower the hydrolysis rate. In pair A, ethyl benzoate undergoes hydrolysis more quickly than methyl benzoate because the ethyl group has less steric hindrance than the methyl group. In pair B, isopropyl acetate undergoes hydrolysis more quickly than N-propyl acetate because the branched isopropyl group has less steric hindrance than the straight chain N-propyl group.

Explanation:

The percent of chloride ion in a sample if 2. 500 g of the sample produces 1. 750 g of agcl when treated with excess ag⁺ is 17.2 percent.

What is mass percent?

The ratio of the mass of the solute contained in a solution to the mass of the solution as a whole is known as the mass percent.

Explanation:

Given:

Mass of sample = 2. 500 g

Mass of AgCl = 1. 750 g

The percent of chloride ion in a sample is calculated as,

Molar mass of AgCl = 143.32 g/mol

\(Molar mass of Chlorine atom = 35.45 g/mol\)

Assume that all of the sample's chlorine has precipitated into silver chloride. As a result, the amount of chlorine in silver chloride will match the amount of chlorine in the sample.

First we have to find mass of chlorine,

\(In 143.32 g of silver chloride, mass of chlorine present is 35.45 gSo, in 1.3487 g of silver chloride, mass of chlorine present will be =35.45g/143.32 g * 1.750 g = 0.43 g\)

Therefore, the percent of chloride ion in a sample is

\(Mass of pure chloride compound = 2.500 gMass of chlorine = 0.43 g%Chlorine = 0.43/2.5 *100%Chlorine = 17.2 %\)

Hence, the percent of chloride ion in a sample is \(17.2%\) percent.

a) The absolute standard deviation of the concentration of NaOH is 0.0041 M.

b) The standard error of the concentration of NaOH is 0.0018 M.

c) The confidence interval of the concentration of NaOH is (0.1033 M, 0.1060 M).

d) Yes, the sample mean is significantly different from the true concentration of 0.1045 M.

e) No, the mean concentrations from the two students' results are not similar to each other.

a) To calculate the absolute standard deviation of the concentration of NaOH, we need to find the standard deviation of the given data points. Using the formula for sample standard deviation, we calculate the average deviation of each data point from the mean concentration, then square each deviation, take the average of the squared deviations, and finally, take the square root. The absolute standard deviation is the absolute value of the standard deviation.

b) The standard error of the concentration of NaOH measures the variability of the sample means from different samples. It is calculated by dividing the standard deviation by the square root of the sample size. In this case, the sample size is 5.

c) To calculate the confidence interval of the concentration of NaOH, we need to determine the margin of error using the t-distribution and the sample standard deviation. With a 95% confidence level, we use a t-value corresponding to 4 degrees of freedom (n-1) and multiply it by the standard error. The confidence interval is constructed by subtracting and adding the margin of error to the sample mean concentration.

d) To determine if the sample mean is significantly different from the true concentration, we compare the true concentration to the confidence interval. If the true concentration falls outside the confidence interval, then the sample mean is significantly different from the true concentration.

e) To assess if the mean concentrations from the two students' results are similar to each other, we can calculate the confidence intervals for each student's data. If the confidence intervals overlap or are close to each other, it suggests that the mean concentrations are similar. However, if the confidence intervals do not overlap, it indicates that the mean concentrations are likely different.

Answer: Therefore, approximately 0.1247 moles of ammonia can be produced from the given reaction.

Explanation:

To determine the number of moles of ammonia (NH3) produced from the given reaction, we need to use the ideal gas law and stoichiometry.

The balanced chemical equation for the reaction between hydrogen (H2) and nitrogen (N2) to form ammonia (NH3) is:

N2 + 3H2 → 2NH3

From the equation, we can see that three moles of hydrogen react with one mole of nitrogen to produce two moles of ammonia.

First, let's convert the given conditions of hydrogen to the appropriate units for the ideal gas law:

Volume of hydrogen = 4.0 liters

Temperature of hydrogen = 50.0°C = 50.0 + 273.15 = 323.15 K

Pressure of hydrogen = 1.2 atm

Now, let's calculate the number of moles of hydrogen using the ideal gas law equation:

PV = nRT

where:

P = pressure (in atm)

V = volume (in liters)

n = number of moles

R = gas constant (0.0821 L·atm/(mol·K))

T = temperature (in Kelvin)

n(H2) = PV / RT

n(H2) = (1.2 atm) * (4.0 L) / (0.0821 L·atm/(mol·K) * 323.15 K)

≈ 0.187 mol

Since the stoichiometry ratio is 3:2 (H2:NH3), we can conclude that 0.187 moles of hydrogen can produce (0.187/3) * 2 = 0.1247 moles of ammonia.

The pH value where benzoic acid and dibromobenzene would be in different layers in extraction is 7.

Benzoic acid is a weak acid and has a pKa of 4.2, which means it will exist mostly in the form of the acid (HA) at pH values lower than 4.2 and mostly in the form of the salt (A-) at pH values higher than 4.2.

Dibromobenzene is a neutral compound and its pH does not affect its behavior.

If we take pH = 7 which is higher than the pKa of benzoic acid, benzoic acid will exist mostly in the form of salt (A-) in this pH range and Dibromobenzene will remain neutral.

So, Benzoic acid will be in the aqueous layer and Dibromobenzene will be in the organic layer during extraction.
