How will these changes affect the yield (increase, reduction, no change) of the products:
The product of a step doesn't get fully dried.
We weighed 14 g of a reactant instead of 15 g which are required for the experiment, but we noted down 15 g.
A reactant that has to be heated in order to produce another product, doesn't get enough heated.
If a solid gets rinsed with only cold water, but not with acetone.
For the first one, I believe that the yield will increase, because the product won't be fully dried and the water will add mass to the product.
For the fourth one, I believe that since we are not using acetone, the product won't be dry enough, so it will also increase the yield.
For the third one, I'm not sure. But I believe if the product is not heated enough, less product will be formed, so the yield will be reduced.
For the second one, I'm also not sure.
