Calcium carbonate decomposes into calcium oxide and carbon dioxide as shown below. If 20.7 grams of CaCO3 decompose, what is the theoretical yield in grams of CaO? If 6.81 grams of CaO are actually recovered, what is the percent yield?

CaCO3 --> CaO + CO2

**Your answer should be written as XX. X

Percentage yield =58.7 %

Explanation:

moles of calcium carbonate as a reactant =

as per molar equation , 0.2068 moles of calcium carbonate produces 0.2068 moles of CaO .

amount of CaO = 0.2068 mole x (40.078+15.999) g/moles = 11.598 gram

percentage yield = actual yield /  theoritical yield =  6.81/ 11.598 = 0.587 or 58.7 %

s too much pool water may lead to chlorine poisoning. the concentration of chlorine in public drinking water is extremely low and not harmful to human health. sooo yeahh

explanation:

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.
