What is the theoretical yield of ethyl chloride in the reaction of 27.17 g of ethylene with 58.33 g of hydrogen chloride? (for ethylene, mw=28.0 amu; for hydrogen chloride, mw=36.5 amu; for ethyl chloride, mw=64.5 amu.) report your answer to the nearest hundredth of a gram without units.

h2c=ch2 + hcl → ch3ch2cl

63.83.

Explanation:

1.0 mole of ethylene reacts with 1.0 mol of HCl to produce ethyl chloride.

no. of moles of ethylene = mass/molar mass = (27.71 g)/(28.0 g/mol) = 0.9896 mol.

no. of moles of HCl = mass/molar mass = (58.33 g)/(36.5 g/mol) = 1.589 mol.

Now, we need to find the no. of moles of produced ethyl chloride:

∵ 1.0 mole of ethylene produce → 1.0 mole of CH₃CH₂Cl.

∴ 0.9896 mole of ethylene produce → 0.9896 mole of CH₃CH₂Cl.

The mass produces of ethyl chloride = no. of moles x molar mass = (0.9896 mol)(64.5 g/mol) = 63.83 g.

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.

the answer is a. co2, this would be colder than the : )
