The decomposition of 3.32 g caco3 yields 1.24 g cao. what is the percent yield of this reaction? (caco3 --> cao + co2)

66.57%

Explanation:

The decomposition reaction of calcium carbonate is shown below as:

Calculation of moles of :

Amount = 3.32 g

Molar mass of = 100 g/mol

The formula for the calculation of moles is shown below:

Thus, moles are:

According to reaction,

0.0332 moles of decomposes to yield 0.0332 moles of

Theoretical yield = 0.0332 moles

Calculation of moles of formed as:

Amount = 1.24 g

Molar mass of = 56 g/mol

The formula for the calculation of moles is shown below:

Thus, moles are:

Experimental yield = 0.0221 moles

Thus,

Percent yield = 66.57%

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.

they are all solids.
