Answer:

When an acetic acid solution is titrated with sodium hydroxide, the slope of the titration curve (pH versus volume of NaOH added) increases when sodium hydroxide is first added. This change shows that <u>acetic acid is being converted to sodium acetate.</u>

Explanation:

<u>ABOUT TITRATION -</u> Titration is a chemical analysis method for determining the amount of a constituent in a sample by adding an exact known quantity of another substance to the measured sample with which the desired constituent reacts in a specific, known proportion. A burette, which is essentially a long, graduated measuring tube with a stopcock and a delivery tube at the bottom end, is used to gradually administer a standard solution of titrating reagent, or titrant.

It is feasible to identify a good visual color indicator for many titration processes that will signify the end point at, or very near to, the equivalence point.

Acid-base titrations, precipitation titrations, complex-formation titrations, and oxidation-reduction (redox) titrations are examples of such titrations, which are categorised according to the nature of the chemical reaction that occurs between the sample and the titrant.

Titrations of metal ions with the reagent disodium ethylenediaminetetraacetate are the most important titrations based on complex-formation processes (a salt of edetic acid, or EDTA).

<u>Hence , the answer is that acetic acid is converted into sodium acetate.</u>

the molecular weight of the nitrous oxide is 44.013 g/mol. assuming standard temperature and pressure, what would be the volume,
allsm [11]

The volume of the nitrous oxide gas is 1729.3 Liters

<h3>What is the number of moles of gas present in 3.40 kg of nitrous oxide?</h3>

The number of moles of gas present in 3.40 kg of nitrous oxide is determined from the formula below:

Numbers of moles = mass/molar mass

the mass of nitrous oxide = 3.40 kg or 3400 g

the molar mass of nitrous oxide = 44.013 g/mol

Moles of gas = 3400 / 44.013

Moles of gas = 77.25 moles

Using the ideal gas equation to determine the volume of the gas:

PV= nRT

V = nRT/P

where;

  • V is the volume of gas
  • n is the number of moles of gas
  • R is molar Gas constant = 0.082 L.atm/mol/K
  • T is the temperature of the gas

V = 77.25 * 0.082 * 273 / 1

The volume of the gas = 1729.3 Liters

Combustion analysis of naphthelene, a hydrocarbon used in mothballs, produces 13.20g CO2 and 1.80g H2O. Calculate the empirical
guapka [62]
Answer: C₃H₂

Explanation:

1) Since you are told naphthelene is a hydrocarbon, you know that its chemical formula only has atoms of C and H.

2) Since combustion adds O but not C nor H, you know that all the C and H present in the products come from the naphthelene sample.

3) Calculate the amount of C in 13.20 grams of CO₂:

Use atomic masses:

C: 12.01 g/mol
O: 16.00 g/mol

⇒ molar mass of CO₂ = 12.01 g/mol + 2×16.01 g/mol = 44.01 g/mol

Proportion of C in 13.20 g of CO₂

12.01 g C / 44.01 g CO₂ = x / 13.20 g CO₂ ⇒ 

x = 13.20 g CO₂ × 12.01 g C / 44.01 g CO₂ = 3.602 g C

3) Calculate the mass of H in 1.80 g of H₂O

Atomic masses:

H: 1.01 g/mol
O: 16.0 g/mol

Molar mass H₂O = 18.02 g/mol

Proportion of H in 1.80 g H₂O

2.02 g H / 18.02 g H₂O = x / 1.80 g H₂O

x = 1.80 gH₂O × 2.02 g H / 18.02 gH₂O = 0.202 g H.

4) Calculate the number of moles of C and H in the masses calculated above

Number of moles of C = 3.602 g C / 12.01 g/mol = 0.3 mol

Number of moles of H = 0.202 g  / 1.01 g/mol = 0.2 mol

5) Divide both amounts by the smallest one to calculate the proportion in moles:

C: 0.3 / 0.2 = 1.5 mol

H = 0.2 / 0.2 = 1 mol


Multiply by 2 to obtain integers:

C: 3
H: 2

6)  Then the proportion leads to the empirical formula C₃H₂
