Explanation:
Hello there!
In this case, according to the given chemical reaction:
![4C_2H_3Cl + 7O_2 \rightarrow 8CO + 6H_2O + 2Cl_2](https://tex.z-dn.net/?f=4C_2H_3Cl%20%2B%207O_2%20%5Crightarrow%208CO%20%2B%206H_2O%20%2B%202Cl_2)
It turns out possible for us to realize about the 7:8 mole ratio of O2 to CO, and therefore, the theoretical yield of the latter is calculated via stoichiometry:
![m_{CO}=57.8gO_2*\frac{1molO_2}{32.0gO_2}*\frac{8molCO}{7molO_2} *\frac{28.01gCO}{1molCO} =57.82gCO](https://tex.z-dn.net/?f=m_%7BCO%7D%3D57.8gO_2%2A%5Cfrac%7B1molO_2%7D%7B32.0gO_2%7D%2A%5Cfrac%7B8molCO%7D%7B7molO_2%7D%20%20%2A%5Cfrac%7B28.01gCO%7D%7B1molCO%7D%20%3D57.82gCO)
Finally, the percent yield is calculated by dividing the actual yield, 36.5 g by the just computed theoretical one:
![Y=\frac{36.5g}{57.8g} *100\%\\\\Y=63.1\%](https://tex.z-dn.net/?f=Y%3D%5Cfrac%7B36.5g%7D%7B57.8g%7D%20%2A100%5C%25%5C%5C%5C%5CY%3D63.1%5C%25)

Answer:
Dicalcium phosphate. (I'm sure meant for the "o" to be an "a" for Calcium).
