Answer : Option B) Attempt to control the conditions.
Explanation : While conducting an experiment, a scientist should always attempt to control the reaction conditions.
If the reaction conditions are not controlled one can lose the expected result or observation that was supposed to be generated from the experiment. Like controlling the given temperature, pressure, addition of catalysts, etc. If these conditions are overlooked one may not achieve the expected results and will not reach to the conclusion.
Answer: 94.07%
Explanation:
Percentage yield can be calculated by the formula
%yield = Experimental yield/Theoretical yield x100
Experimental yield = 7.93g
Theoretical yield = 8.43
%yield = Experimental yield/Theoretical yield x100
%yield = 7.93/8.43 x 100 = 94.07%
