To find the percentage yield, first calculate the theoretical yield of CaO that should be produced from 4.5 kg of limestone. The molar mass of CaCO3 is approximately 100.09 g/mol, and the molar mass of CaO is about 56.08 g/mol. From these values, calculate the theoretical yield in grams and then convert it to kilograms. Finally, divide the actual yield (2.5 kg) by the theoretical yield and multiply by 100 to find the percentage yield.

When limestone CaCO3 is roasted quicklime is produced according to equation actual yield of CaO is 2.5 kg when 4.5 kg of limestone is roasted what is percentage yield?

Percentage yield can be calculated by dividing the actual yield by the theoretical yield (based on stoichiometry) and multiplying by 100. The molar mass of CaCO3 is 100 g/mol, so 4.5 kg is 45,000 g. The theoretical yield of CaO can be calculated using stoichiometry: 1 mol of CaCO3 produces 1 mol of CaO. Thus, 45,000 g CaCO3 = 500 mol CaCO3 = 500 mol CaO = 28,000 g CaO. Percentage yield = (Actual yield / Theoretical yield) * 100 = (2.5 kg / 28 kg) * 100 = 8.93%.


How is lime mined?

Limestone may be mined in a surface quarry, typically by drilling, blasting, and crushing the shot rock. In some areas, limestone mines are underground. In Florida, some limestone mines are under water- the rock is drilled, shot, and mucked while under water. Limestone may be crushed to aggregate sizes, or finely crushed to a powder state for agricultural limestone, or used a "mine safety dust" to control methane and dust in coal mines. Powdered limestone (calcium carbonate) may be roasted and hydrated to form quicklime (Calcium oxide or calcium hydroxide)


Do you have to use raw nuts in peatnut brittle?

Using raw nuts in peanut brittle is recommended because they will be roasted during the cooking process and develop a more intense flavor and crunch. If you use already roasted nuts, they may become overcooked and lose their intended flavor and texture in the final product.


Are roasted chickpeas acidic or alkaline?

Roasted chickpeas are slightly acidic due to their natural pH level. However, once consumed, the body metabolizes chickpeas and they have an alkalizing effect on the body. Overall, they are considered to be more alkaline-forming in the body.


Are roasted peanuts an ionic or covalent?

Roasted peanuts contain both ionic and covalent compounds. The salt used for roasting the peanuts (e.g., sodium chloride) is made of ionic bonds, while the organic compounds in the peanut itself, such as fats and proteins, are held together by covalent bonds.

Can Limestone be used for the smell of a decompostion of a dead animal?

Lime (quicklime) is made from limestone- but it is not the same thing. Agricultural lime is powdered limestone. Quicklime is limestone (calcium carbonate) that has been roasted and changed to Calcium Oxide. Slaked quicklime is quicklime that has had water added- Calcium hydroxide. Quicklime is used for odor control.


Why can some people although allergic to peanuts still ingest smooth peanut butter without a reaction?

Because some smooth peanut butter contains peanuts that have not been roasted. In China peanuts are boiled, not roasted.
