Answer:
Both have densities greater than that of water
Explanation:
The ability of objects to either float or sink in a liquid depends on their relative densities.
If an object is denser than a liquid it will completely sink in it, but if the density of the object is less than that of the liquid, it will sink until the weight of liquid displaced is equal to the weight of the object, then it will finally float in that liquid.
In the case of the stone bead and iron beads dropped into a cup of water, hey both sank to the bottom because they are denser than water.
Answer:
1,39 L
Explanation:
Charle's Law states that the volume of a fixed amount of gas <em>maintained at constant pressure</em> is directly proportional to the<u> absolute temperature</u> of the gas, for a constant amount of gas we can write:
As the pressure of the balloon doesn't change, we can use Charle's Law to solve the problem. Firs we change the given temperatures to absolute temperature units ( °K), using the following relations:
°K=273+°C
°K=5/9(°F-32)+273
Therefore:
V1=1.5 L, T1=273+25=298°K
V2=?, T2=5/9(36-32)+273=275,2°K
The new volume of the balloon is 1,39 L.
When 2-pentanol gets oxidized you end up with 2-pentanone. In this case, since we are oxidizing a secondary alcohol you end up with a ketone. They cannot be oxidized further than that. If it was a primary alcohol you would end up with an aldehyde.
You can find the mechanism as well the molecule formula of both 2pentanol and 2pentanone attached.
