100 mL graduated cylinder because the device is more precise.
Answer:
Liquid
Explanation:
had this ln a test and got it right
Answer: Catalyst
Explanation: it speeds it up lol but basically the catalyst helps speed up the chemical reaction by reducing the activation energy or changing the reaction machenism/
Answer:
A
Explanation:
because it can share and remain with ither electrons
Answer:
The answer is "Choice a".
Explanation:
In the given question, through the basis of their determined percentage yield, a smaller copper increase in value and less copper has been lost during decanting, but now this mistake in your experiment was the cause of confusion, and the wrong choice can be defined as follows:
- In point b, it is wrong because A few other solids were not lost during decanting, resulting in a higher recovery of copper as well as a boost in the percentage yield
- In point c, it is wrong because whenever the vapor bath was dried, the specimen did run dry totally, which did result in such a heavier density of copper and a larger percentage of the yield.
- In point d, it is wrong because whenever the vapor bath was dried, the sample was fully dried, which also resulted in much less adhesive weight and a much less percentage of the yield.
