9. How many moles of H2SO4 are required to completely react with 8.3 mol Al?
Answers
ANSWER
12.45 moles of H2SO4 will reacts completely with 8.3 mol of Al
EXPLANATION
Given information
The number of moles of Al is 8.3 mol
To find the number of moles of H2SO4 that reacts with Al, you will need to follow the steps below
Step 1: Write a balanced equation between the reaction Al and H2SO4
\(\text{ 2Al}_{(s)}\text{ + 3H}_2SO_{4(aq)}\rightarrow Al_2(SO_4)_{3(aq)}\text{ + 3H}_{2(g)}\)The aim of the above reaction is to produce hydrogen gas. From the above reaction, you will see that 2 moles of aluminum react with 2 moles of H2SO4.
Since we already know the number of moles of Al, therefore, we can calculate the number of moles of H2SO4 using a stoichiometric ratio
Step 2: Find the number of moles of H2SO4
Let x represents the number of moles of H2SO4
According to their stoichiometric ratio; 2 moles of Al react with 3 moles of H2SO4
\(\begin{gathered} \text{ 2 moles of Al }\rightarrow\text{ 3 moles of H}_2SO_4 \\ \text{ 8.3 moles of Al }\rightarrow\text{ x moles of H}_2SO_4 \\ \text{ cross multiply} \\ \text{ 2 moles of Al }\times\text{ x moles of H}_2SO_4\text{ = 3 moles of H}_2SO_4\times\text{ 8.3 moles of Al} \\ \text{ x moles of H}_2SO_4\text{ = }\frac{3\text{ moles of H}_2SO_{4\text{ }}\times8.3\cancel{moles\text{ of Al}}}{2\cancel{moles\text{ of Al}}} \\ \text{ x moles of H}_2SO_4\text{ = }\frac{3\text{ }\times8.3}{2}\text{ moles of H}_2SO_{_4} \\ \text{ x moles of H}_2SO_4\text{ = }\frac{24.9}{2}\text{ moles of H}_2SO_4 \\ \text{ x moles of H}_2SO_4\text{ = 12.45 moles} \end{gathered}\)Hence, 12.45 moles of H2SO4 will reacts completely with 8.3 mol of Al
6.Explain the bonding that occurs between sodium and chlorine. Specifically, what kind of bonding takes place, what’s the name of the resulting compound, and what properties would you expect this compound to have with respect to water?
Answers
The easiest way to determine the type of bonding that occurs between sodium and chlorine is to find the difference of their electronegativities.
Sodium has an electronegativity of 0.93 and chlorine an electronegativity of 3.16:
\(3.16-0.93=2.23\)The difference of electronegativities is 2.23, which is greater than 1.7. It means that they form a ionic bond.
The resulting compound is what we know as table salt, which is NaCl, sodium chloride.
We expect that this compound is soluble in water.

To determine the number of grams of sodium sulfate formed, we need to calculate the molar masses of sodium hydroxide (NaOH) and sodium sulfate (Na2SO4) and use stoichiometry.
The molar mass of NaOH:
Na = 22.99 g/mol
O = 16.00 g/mol
H = 1.01 g/mol
Molar mass of NaOH = 22.99 + 16.00 + 1.01 = 40.00 g/mol
The molar mass of Na2SO4:
Na = 22.99 g/mol
O = 16.00 g/mol
S = 32.07 g/mol
Molar mass of Na2SO4 = 2 * 22.99 + 4 * 16.00 + 32.07 = 142.04 g/mol
Now, we can set up the stoichiometric ratio using the balanced equation:
2 NaOH + H2SO4 → 2 H2O + Na2SO4
From the equation, we can see that 2 moles of NaOH react with 1 mole of H2SO4 to produce 1 mole of Na2SO4.
First, calculate the number of moles of NaOH:
Moles of NaOH = Mass of NaOH / Molar mass of NaOH
Moles of NaOH = 200 g / 40.00 g/mol = 5.00 mol
Since the ratio between NaOH and Na2SO4 is 2:1, the number of moles of Na2SO4 formed will be half of the moles of NaOH.
Moles of Na2SO4 = 0.5 * Moles of NaOH = 0.5 * 5.00 mol = 2.50 mol
Finally, calculate the mass of Na2SO4:
Mass of Na2SO4 = Moles of Na2SO4 * Molar mass of Na2SO4
Mass of Na2SO4 = 2.50 mol * 142.04 g/mol = 355.10 g
Therefore, if you start with 200 grams of sodium hydroxide and have an excess of sulfuric acid, approximately 355.10 grams of sodium sulfate will be formed.

What is the empirical formula for a
compound that contains 0.126 mol CI
and 0.44 mol O?
Answers
Answer:
In Explanation
Explanation:
The empirical formula of a compound is the simplest whole-number ratio of atoms in a molecule. To find the empirical formula of a compound that contains 0.126 mol CI and 0.44 mol O, we can divide the number of moles of each element by the smallest number of moles among all the elements present. This will give us the simplest ratio of atoms in the compound.
First, we can divide the number of moles of CI by the number of moles of O:
CI/O = 0.126 mol / 0.44 mol = 0.2857
This means that for every atom of oxygen, there are 0.2857 atoms of chlorine.
To simplify this ratio, we can multiply both sides of the equation by the smallest whole number which will make the ratio a whole number. In this case, we can multiply by 4, so the ratio becomes:
CI/O = 4*0.2857 = 1.1428
So the simplified ratio of atoms in the compound is 1 atom of chlorine for every 1 atom of oxygen. The empirical formula is ClO

This technique has been used to identify the presence of gases such as oxygen, methane, and carbon dioxide in the atmospheres of exoplanets.
i) To estimate the frequency of the violet (leftmost) emission, we can use the equation v = c/λ, where v is frequency, c is the speed of light (3.00 x 10^8 m/s), and λ is the wavelength of the emission in meters. The wavelength of the violet emission is 400 nm or 400 x 10^-9 m, so the frequency can be calculated as v = (3.00 x 10^8 m/s) / (400 x 10^-9 m) = 7.50 x 10^14 Hz.
ii) To estimate the energy of the violet emission, we can use the equation E = hv, where E is energy, h is Planck's constant (6.63 x 10^-34 Js), and v is frequency in Hz. Substituting the frequency calculated in part (i), we get E = (6.63 x 10^-34 Js) x (7.50 x 10^14 Hz) = 4.97 x 10^-19 J.
b. The spectral lines are produced by the electrons within the atoms of this element, which can absorb or emit specific amounts of energy to move between different energy levels. These energy transitions result in the emission or absorption of photons with specific wavelengths and frequencies, giving rise to the observed emission spectrum.
c. The violet emission line represents the photon with the most energy since it has the shortest wavelength (400 nm) and highest frequency (7.50 x 10^14 Hz) among the lines shown. This highest energy does not necessarily represent the energy of the valence electrons, but rather corresponds to the specific energy transitions occurring within the atoms of the element.
d. Emission spectra can be used to determine the gases present in the atmosphere of a far-away planet by analyzing the specific wavelengths of the emitted or absorbed light from the planet.

Answers
Answer:
A - right shift
B - no shift
C - right shift
Explanation:
According to Le Chatelier's principle, when a reaction is in equilibrium and one of the factors affecting the rate of reaction is introduced, the equilibrium will shift so as to annul the effects of the constraint.
In this case, decreasing the volume of the reaction's container is equivalent to increasing the pressure of the reaction. When pressure is increased, the reaction will shift towards the side with a lower number of moles.
In A, the total number of moles on the left-hand side of the reaction is two while it is one on the right-hand side. An increase in pressure will, therefore, see the equilibrium shifting to the right-hand side.
In B, the total number of moles on both the right and the left-hand side is two each. An increase in the pressure will have no effect on the equilibrium.
In C, the total number of moles on the left-hand side is two while it is one on the right-hand side. Hence, an increase in the pressure of the reaction will cause a shift in the equilibrium to the right.

The boiling point of water is 100.0 °C, the boiling point of the solution will be : 101.49 °C.The correct answer is option (a) 100.00049 °C.
Ideal Solution : An ideal solution is a homogeneous mixture of two or more components that obeys Raoult's law, which states that each component's vapor pressure is proportional to its mole fraction.The boiling point of a solution depends on the solvent's properties and the solute's concentration. It's dependent on the mole fraction of the solvent and solute, as well as the total concentration of the solution. The change in boiling point of a solution is given byΔTb = Kb × m × i, whereKb = ebullioscopic constant, m molarity of the solution, and i = van't Hoff factor.Assuming that the solution's behavior is ideal, we may use the molality of the solution to compute the boiling point elevation of the solution.The molality of the solution is given by the following formula:m = (n₂ / m₂) ÷ (n₁ / m₁), where n is the number of moles, m is the mass, and the subscripts 1 and 2 refer to water and non-volatile solute sucrose, respectively.The molar mass of sucrose (C₁₂H₂₂O₁₁) is342.3 g/mol; therefore, the number of moles of sucrose is115.0 g ÷ 342.3 g/mol = 0.335 mol.m₁ = mass of water = 350.0 g, and m₂ = mass of sucrose = 115.0 g, as given in the problem.Therefore, the molality of the solution is given by:m = (0.335 mol / 0.115 kg) ÷ (1 mol / 1 kg) = 2.91 mol/kg.Substituting these values in the formula for ΔTb, we get:ΔTb = Kb × m = 0.512 °C m⁻¹ × 2.91 mol/kg = 1.49 °C.100.0 °C + 1.49 °C = 101.49 °C.

burning 12g of urea raise temp of water by 30C what is the enthalpy of combustion for 1kg urea
Answers
The enthalpy of combustion for 1kg of urea is -1223525.84 J/mol.
Urea is a compound that is used in fertilizers and in some plastics.The enthalpy of combustion for urea is the amount of energy that is released when urea is burned. In order to calculate the enthalpy of combustion for 1kg of urea, we need to use the information that is provided to us in the question. Let us start by writing down the balanced equation for the combustion of urea: CO(NH2)2 + 3/2 O2 → CO2 + 2H2O + N2
The balanced equation shows that 1 mole of urea reacts with 1.5 moles of oxygen gas to produce 1 mole of carbon dioxide, 2 moles of water, and 1 mole of nitrogen gas. The enthalpy change for this reaction is equal to the amount of energy that is released when 1 mole of urea is burned.
The heat of combustion (ΔHc) of urea is -632.6 kJ/mol. This means that 632.6 kJ of energy is released when 1 mole of urea is burned. We know that 12g of urea raised the temperature of water by 30°C. We can use this information to calculate the amount of energy that was released when 12g of urea was burned.
The specific heat capacity of water is 4.18 J/g°C. This means that it takes 4.18 J of energy to raise the temperature of 1 gram of water by 1°C. Therefore, it takes 4.18 x 1000 = 4180 J of energy to raise the temperature of 1 kg of water by 1°C.
We know that 12g of urea raised the temperature of water by 30°C. Therefore, the amount of energy that was released when 12g of urea was burned is:
Energy = mass x specific heat capacity x temperature change
Energy = 0.012 kg x 4180 J/kg°C x 30°C
Energy = 1497.6 J
We can now use this information to calculate the enthalpy of combustion for 1kg of urea:
Enthalpy of combustion = energy released / moles of urea burned
Enthalpy of combustion = 1497.6 J / (0.012 kg / 60.06 g/mol)
Enthalpy of combustion = - 1223525.84 J/mol
