Consider the balanced chemical reaction below. when the reaction was carried out, the calculated theoretical yield for water was 176 grams, but the measured yield was 148 grams. what is the percent yield?

Answer;

= 84.09 %

Explanation;

Percent yield represents the ratio between what is experimentally obtained and what is theoretically calculated, multiplied by 100%.

Percentage Yield = actual yield/theoretical yield × 100%

                             = 148 g/176 g × 100%

                             = 84.09 %

If the percent yield is 100%, the actual yield will be equal to the theoretical yield.

Remember that rust prevented by placing a sacrificial electrode in electrical contact with the iron. the sacrificial electrode must be composed of a metal that  oxidizes  more easily than iron (that is, it must be below iron in table 18.1).

Sink to the bottom. addition of potassium nitrate past it’s dissolution capacity at a particular temperature will cause the extra to just sink to the bottom of the glass.however, if you were to raise the temperature of the solution prior to dissolving it, and then slowly decrease the temperature after the dissolution, you would create a “supersaturated” solution - a solution that has more solute dissolved into it than should be allowed. if you add any extra solute past this, the entire solution would “crystallize,” and this is how you get those cool videos on youtube.
