In the Diels-Alder reaction of maleic anhydride and furan, calculate the theoretical yield of the adduct using 1.2g maleic anhydride and 1.00 mL of furan.
Answers
So, the theoretical yield of the adduct in this reaction using 1.2g maleic anhydride and 1.00 mL of furan is 1.83 g.
How to find the limiting reagent to attain the yield of a product?To calculate the theoretical yield of the adduct in the Diels-Alder reaction of maleic anhydride and furan, you first need to determine the limiting reagent. This can be done by calculating the number of moles of each reactant, using their respective molar masses:
- Maleic anhydride (\(C_{4}H_{2}O_{3}\)): 1.2 g ÷ 98.06 g/mol = 0.0122 mol
- Furan (\(C_{4}H_{4}O\)): 1.00 mL ÷ 68.08 g/mol ÷ 1000 = 0.0147 mol
Since maleic anhydride is present in the lower amount, it is the limiting reagent. This means that all of the maleic anhydride will be consumed in the reaction, and the amount of adduct formed will depend on the stoichiometry of the reaction.
The balanced equation for the Diels-Alder reaction of maleic anhydride and furan is:
\(C_{4}H_{2}O_{3}\) + \(C_{4}H_{4}O\) --> \(C_{8}H_{6}O_{2}\)
This shows that one mole of maleic anhydride reacts with one mole of furan to produce one mole of adduct (\(C_{8}H_{6}O_{2}\)).
Therefore, the theoretical yield of the adduct can be calculated by multiplying the number of moles of maleic anhydride (0.0122 mol) by the molar mass of the adduct (\(C_{8}H_{6}O_{2}\), 150.13 g/mol):
Theoretical yield = 0.0122 mol x 150.13 g/mol = 1.83 g

radon-222 is 3.82 days. How much radon will be left after 3.82 days?
Answers
Answer:
The correct answer is - 75 grams.
Explanation:
Half-life is the amount of time that is used by the given amount of substance or element to make it half of the initial amount of a particular radioactive substance.
Equation for alpha decay for radon
\(^222_{86}Rn\Rightarrow^{218}_{84}Po \)

Answers
Temporary and permanent hardness of water Temporary hardness of water is caused by the presence of bicarbonate, carbonate, and sulfate ions, while permanent hardness is caused by the presence of chlorides, sulfates, and nitrates.
Carbonate and bicarbonate hardness can be removed using a process called boiling. Permanent hardness, on the other hand, can be removed using a process called ion exchange.ii. Organic, ortho, and polyphosphorus in wastewaterOrganic phosphorus is present in wastewater in the form of organic molecules like DNA, RNA, and phospholipids. Orthophosphate is the most common form of phosphorus found in wastewater. Polyphosphates, which are a chain of orthophosphate molecules, can also be found in wastewater.iii. Self-cleansing and scouring velocity in sewersSelf-cleansing velocity is the minimum velocity of wastewater flow required to prevent the deposition of solids in the sewer. Scouring velocity, on the other hand, is the minimum velocity required to remove previously deposited solids. Scouring velocity is higher than self-cleansing velocity.
Type 1 and Type 2 settling in water/wastewater treatment Type 1 settling occurs when particles of different sizes and densities settle separately, forming distinct layers.

Answers
The molar mass of element X is 75 g/mol.
m(X₄O₆) = 59.4 g; mass of the compound
m(O) = 14.4 g; mass of oxygen in the compound
n(O) = 14.4 g ÷ 16 g/mol
n(O) = 0.9 mol; amount of oxygen in compound

Calculate the mass of iron produced when 32g of iron (III) oxide is completely reduced by aluminium.
The reaction is shown in the symbol equation:
Fe2O3 + 2Al → 2Fe + Al2O3
Answers
Fe: 55.85 g/mol (atomic mass of iron)
O: 16.00 g/mol (atomic mass of oxygen)
Molar mass of Fe2O3 = 2(Fe) + 3(O) = 2(55.85 g/mol) + 3(16.00 g/mol) = 159.69 g/mol
Molar mass of Al:
Al: 26.98 g/mol (atomic mass of aluminum)
Now, we can calculate the number of moles of Fe2O3 in 32g:
Number of moles = Mass / Molar mass
Number of moles of Fe2O3 = 32 g / 159.69 g/mol ≈ 0.2007 mol
From the balanced equation, we see that the stoichiometric ratio between Fe2O3 and Fe is 1:2. Therefore, for every 1 mole of Fe2O3, we get 2 moles of Fe.
Since the ratio is 1:2, the number of moles of Fe produced will be twice the number of moles of Fe2O3.
Number of moles of Fe = 2 * Number of moles of Fe2O3 ≈ 2 * 0.2007 mol ≈ 0.4014 mol
Finally, we can calculate the mass of Fe produced:
Mass = Number of moles * Molar mass
Mass of Fe = 0.4014 mol * 55.85 g/mol ≈ 22.42 g
Therefore, when 32g of iron (III) oxide is completely reduced by aluminum, approximately 22.42 grams of iron (Fe) will be produced.

C. 2. 4x1024
D. 4. 8 x 10
Answers
The total number of atoms contained in 40 grams of neon is approximately 1.19 x 10^24 atoms.
To determine the total number of atoms in a given mass of a substance, we need to use the concept of moles and Avogadro's number.
First, we need to calculate the number of moles of neon in 40 grams. We can do this by dividing the given mass by the molar mass of neon.
The molar mass of neon (Ne) is approximately 20.18 grams/mole.
Number of moles = Mass / Molar mass
Number of moles = 40 grams / 20.18 grams/mole
Number of moles = 1.98 moles (rounded to two decimal places)
Next, we can use Avogadro's number, which is approximately 6.022 x 10^23 atoms/mole, to convert the number of moles to the total number of atoms.
Total number of atoms = Number of moles × Avogadro's number
Total number of atoms = 1.98 moles × 6.022 x 10^23 atoms/mole
Total number of atoms ≈ 1.19 x 10^24 atoms
Therefore, the total number of atoms contained in 40 grams of neon is approximately 1.19 x 10^24 atoms.

Bubble wrap is made of a series of air pockets sealed in a sheet of plastic and is often used to protect fragile objects during shipping. Bubble wrap tends to pop when stepped onto or squeezed. How can you explain this using Boyle's law?
Answers
Answer:
Explanation:
Boyle's law states that at constant temperature:
P \(\alpha\) \(\frac{1}{V}\)
PV = constant
Where: P is the pressure of a given mass of gas, and V is its volume.
The bubble wrap has a confined volume of air at constant temperature. Since a gas is easily compressible, the volume of the gas in the wrap decreases with increasing pressure. This implies that there is an inverse proportion relation between the pressure on and volume of the air.
The bubble wrap pops when stepped onto or squeezed because the pressure is high and the volume can not be compressed further. Thus, the elastic limit of the seal is exceeded. This leads to an escape of the confined air.
