4.5 % hydrogen

60% carbon

35.5% oxygen

to find say, the percentage of hydrogen, take the amount of hydrogen(6.03) and divide it by the total amount(134.50) with this new answer (.044832714) move the decimal over twice, and round to the highest tenths place. i hope this helps you.

Yes, pulverizing an aspirin is a physical change because it involves breaking down the solid particles of the aspirin without changing its chemical composition.

Salicylic acid is more polar than aspirin because it has a higher solubility in water due to the presence of a hydroxyl group that enhances its polarity. Aspirin, on the other hand, has an ester functional group, which reduces its overall polarity compared to salicylic acid.

The common paracetamol tablet is approximately 1cm long anyway. Depending on the manufacturer, aspirin may come in different shapes, but I think it's a fair assumption to say the longer end is approx 1cm

Aspirin purity can be tested using acid-base indicators such as phenolphthalein or bromothymol blue. These indicators change color based on the pH of the solution, allowing for a qualitative assessment of purity. However, more precise quantitative methods such as spectrophotometry or chromatography are typically used for accurate purity testing of aspirin.

No, aspirin is a compound made up of carbon, hydrogen, and oxygen atoms. It is not an element that can be found on the periodic table.

Aspirin is a white crystalline powder with a melting point of 135°C.

The common chemical name for aspirin is acetylsalicylic acid. Its systematic name is 2-(acetyloxy)benzoic acid. The chemical formula of aspirin is C9H8O4.

It is generally safe to take ibuprofen with Alka-Seltzer Cold, but it's always best to consult with a healthcare provider or pharmacist before combining medications to ensure there are no potential interactions or contraindications.

The literature value for the melting point of aspirin is approximately 135-136 degrees Celsius.

The active medical ingredient in Aspirin is acetylsalicylic acid, or A.S.A.

To determine the number of molecules in a 500 mg tablet of acetaminophen (C8H9NO2), follow these steps:

1. Calculate the molar mass of acetaminophen (C8H9NO2) by adding the atomic masses of each element present (C: 12.01, H: 1.01, N: 14.01, O: 16.00). This gives a molar mass of 151.17 g/mol.
2. Convert the mass of the tablet (500 mg) to grams (0.5 g).
3. Use the molar mass to calculate the number of moles in 0.5 g of acetaminophen.
4. Finally, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to the number of molecules in the tablet.

Water-aspirin can potentially enhance plant growth by acting as a stress reliever and stimulating the plant's natural defense mechanisms. Aspirin contains salicylic acid, which can help plants fight off diseases and increase their resilience to environmental stressors. However, it is important to use water-aspirin solutions in moderation to avoid negative effects on plant health.

Aspirin is hydrolyzed in the body to salicylic acid by esterases in the liver. This process involves cleaving the acetyl group from the salicylate molecule to form salicylic acid, which is then further metabolized to various metabolites. Salicylic acid is the active metabolite responsible for the anti-inflammatory and analgesic effects of aspirin.

It is possible to extract salicylic acid, a precursor to aspirin, from certain plants like willow bark; however, most aspirin is now synthesized in a laboratory setting. Harvesting aspirin from plants is not common practice due to efficiency and cost considerations.

When aspirin is dissolved in water, it forms acetylsalicylic acid, which is a weak acid. In water, aspirin molecules release hydrogen ions (H+) into the solution, making it slightly acidic. The extent of acidity will depend on the concentration of the aspirin solution.

To calculate the mass percent of acetylsalicylic acid in the tablet, divide the mass of acetylsalicylic acid (325 mg) by the total mass of the tablet (2000 mg), then multiply by 100 to get the percentage. So, (325 mg / 2000 mg) * 100 = 16.25%. Therefore, the mass percent of acetylsalicylic acid in the tablet is 16.25%.

The atom economy of aspirin synthesis is relatively high, around 90%. This means that about 90% of the reactant atoms are found in the final product, while only around 10% are considered waste. This efficiency is one of the reasons why the synthesis of aspirin is considered to be environmentally friendly.

The order of increasing polarity for these substances is: caffeine < ibuprofen < acetaminophen < aspirin. Caffeine is the least polar, whereas aspirin is the most polar among these common pain relievers.

Aspirin is classified under antipyretic (decreases temperature) and a non-opioid analgesic (reduces pain). It can also be used as a anti-thrombolytic (anti-clotting agent- 81mg) It makes the platelets (blood component responsible for clotting) slippery so they don't stick to anything in the vessels, which decreases your risk of DVT (blood clots).

Vacuum filtration was used instead of gravity filtration in the isolation of aspirin to speed up the filtration process by applying negative pressure to draw the solvent through the filter paper more quickly. This helps to separate the solid product from the solvent more efficiently and saves time in the isolation process.

Phosphoric acid is used in the synthesis of aspirin as a catalyst to facilitate the esterification reaction between salicylic acid and acetic anhydride. It helps increase the reaction rate and yield of aspirin.

The functional groups of anything are the croups that aren't normal alkane (single carbon-hydrogen bonds) groups. In the case of Ibuprofen there are two functional groups. The first is the aromatic group or Benzene ring in the centre of the structure. The second is the carboxylic acid group (Oxygen double bonded to two

Maintaining the temperature at 90 degrees C in the synthesis of aspirin helps to achieve optimal reaction kinetics, ensuring the reaction proceeds at a suitable rate. This temperature also promotes the formation of the desired product while minimizing the formation of unwanted byproducts.

Aspirin is derived from salicylic acid and acetic anhydride in a reaction that involves acetylation. The synthesis typically takes place under acidic conditions and involves the formation of acetylsalicylic acid and acetic acid as byproducts. The final product is then purified through recrystallization.

The ingredients needed to produce aspirin are salicylic acid and acetic anhydride. Acetic acid is also produced as a byproduct during the chemical reaction.
