H2SO4 is our limiting reactant, and moles of H2SO4 will dictate the maximum amount of product that can be formed.
The correctly balanced equation for the reaction:
H2SO4(aq) + 2NaOH(s) ==> Na2SO4(aq) + 2H2O(l)
To find the limiting reactant. Divide moles of each reactant by the corresponding coefficient in a balanced equation and see which is less
For H2SO4: 29 g H2SO4 x 1 mol H2SO4/98 g = 0.294 mols (÷1->0.294)
For NaOH: 12 g NaOH x 1 mol NaOH / 40. g = 0.3 mols (÷2->0.15)
Since 0.294 is less than 0.15, H2SO4 is our limiting reactant, and moles of H2SO4 will dictate the maximum amount of product that can be formed
If the reaction finishes, there can be no more than zero grams of H2SO4 left over. There shouldn't be any left-over since it will run out before the NaOH is consumed.

suppose that a chemist combines 253 ml of methane and 891 ml of chlorine at stp in a 2.00 l flask. the flask is then allowed to stand at 298 k. if the reaction reaches 81.8% completion, what is the total pressure in the flask?
The total pressure in the flask is determined by the ideal gas law which is 4.00 atm.
This law states that the pressure of a gas is equal to its number of moles times its temperature divided by its volume. For this question, we need to calculate the number of moles of each gas before the reaction.
Methane has a molar mass of 16.04 g/mol,
so 253 mL of methane would be 1.106 moles.
Chlorine has a molar mass of 35.45 g/mol,
so 891 mL of chlorine would be 2.587 moles.
Thus, the total number of moles in the flask is 3.693.
Next, we need to calculate the number of moles that have reacted. 72.5% of the reaction has been completed, so 0.725 moles of the 3.693 moles have reacted.
Finally, the total pressure in the flask is equal to the number of moles times the temperature divided by the volume. This gives a pressure of 4.00 atm.

determine the molality of a solution prepared by dissolving 4.11 g of potassium chloride in 64.3 g of water.
The molality of the solution is 0.064 mol/kg. Molality is defined as the number of moles of solute per kilogram of solvent.
To calculate molality, we need to first find the number of moles of solute (potassium chloride) and then divide it by the mass of solvent (water) in kilograms.
The number of moles of solute can be calculated using the formula: moles = mass/molar mass, where the molar mass of potassium chloride is 74.55 g/mol.
So, the number of moles of potassium chloride in the solution is: 4.11 g / 74.55 g/mol = 0.055 mol
The mass of water in kilograms can be calculated using the formula: mass in kg = mass in g / 1000 g/kg, where the mass of water in the solution is 64.3 g.
So, the mass of water in the solution is: 64.3 g / 1000 g/kg = 0.064 kg
Finally, the molality of the solution can be calculated using the formula: molality = moles of solute/mass of solvent in kg
So, the molality of the solution is: 0.055 mol / 0.064 kg = 0.064 mol/kg

carbon-14 has a half life of 5730 years. how many years have passed when 1/4th of the original amount of carbon-14 remains?
Carbon-14 has a half life of 5730 years. So, approximately 5530 years have passed when 1/4th of the original amount of carbon-14 remains.
The number of years that have passed when 1/4 of the original amount of carbon-14 remains can be determined by using the equation for radioactive decay:
N = N0 * [tex](1/2)^{(t/T)}[/tex]
where,
N = the amount of radioactive isotope at time t,
N0 = the initial amount of radioactive isotope,
t = the time that has passed,
T = the half-life of the isotope.
Setting N equal to N0 / 4 and solving for t:
t = T * ln(2) * ln(N0/N)
Plugging in the known values:
T = 5730 years, N0 = N0, N = N0 / 4
t = 5730 * ln(2) * ln(N0/N0 / 4)
t = 5730 * ln(2) * ln(4)
t = 5730 * 0.693 * 1.386
t = 5730 * 0.961

The acid protonates the carbonyl carbon of the ester during the reaction, making it a suitable leaving group. The resultant intermediate subsequently reacts with water, and the hydroxide ion then attacks the carbonyl carbon as a nucleophile. The protonated ester acts as the leaving group, which is then ejected from the reaction via an SN2 mechanism, resulting in the production of the carboxylic acid and alcohol components.

The new concentration of the solution would be 1.0 m (C)
A solution's concentration can be lowered through a process known as dilution, which involves adding more solvent to the solution. This procedure maintains the solute concentration while increasing the overall volume of the solution, lowering the ultimate concentration. A solution having a higher concentration can be diluted by combining it with a solution with a lower concentration. Mathematical calculations can be used to determine how much solvent is required to create a new, diluted solution at the desired concentration. The following formula describes the connection:
M₁V₁ = M₂V₂
Where:
M₁ = the concentration of the original solution
V₁ = the volume of the original solution
M₂ = the concentration of the diluted solution
V₂ = the volume of the diluted solution
Thus, the new concentration would be
2.0 m × 200 mL = M₂ × 400 mL
