In the reaction between co and fe3o4, the theoretical yield in an experiment is calculated to be 47.2 gfe. when a careless chemistry student carries out the experiment, the actual yield is 42.9 fe. calculatethe percentage yield.
a) 88.5%
b) 70.2%
c) 89.9%
d) 74.3%
e) 90.9%

The percentage yield is 90.9 % (option e)

Explanation:

A simple rule of three to explain this.

If the theoretical yield of the reaction is 47.2 g Fe, we assume it as 100%, then what percentage of yield means 42.9 g Fe

47.2 g Fe 100 %

42.9 g Fe ( 42.9  .  100)/ 47.2 = 90.88%

"a connection, a bond or common feeling between two people", or as a chemical process it stimulates love or sexual attraction

the answer to this question is 3.
