a piece of wood sinks in ethanol but floats in gasoline. what can you determine about the three different densities?
2 answers:
Answer: gasoline has more density than wood and wood has more density than gasoline.
Explanation:
Density is defined as the mass contained per unit volume.
A substance having more density will sink at the bottom and the substance having less density will float at the top.
As the wood sinks in ethanol , it means wood has more density than ethanol.
As the wood floats in gasoline, it means wood has less density than gasoline.
Hence, the order of density will be gasoline > wood > ethanol.

Answer:
87.15%
Explanation:
To find percent yield, we can use this simple equation
Where "Actual" is the amount in grams actually collected from the reaction, and "Theoretical" is, well, the theoretical amount that should have been produced.
They give us these values, so to find the percent yield, just plug the numbers in.
So, the percent yield is 87.15%
An easy trick to remember how to do this is just to divide the smaller number by the bigger number and move the decimal back two places. If you have a percent yield greater than 100%, something is wrong in the reaction.
