Answer:
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,
<u>Percent yield = 66.57%</u>
Answer:
sample response:
The chemical is the same but the concentration is different.
The chemical is more dangerous in its highly concentrated form.
Although the chemicals are the same, they require different handling procedures. Therefore specific information should be available for each.
