Ilsa showed her parents a trick she learned in science class. She used water to make ice cubes. Ilsa then placed some ice cubes

in a glass containing a clear liquid. The ice cubes floated. She then placed some ice cubes in another glass that also contained a clear liquid. In this glass, the ice cubes sank to the bottom of the glass. Ilsa did not tell her parents that the first glass contained water while the second glass contained rubbing alcohol. What can you conclude from this information?
A.
The ice cubes changed their density.
B.
Water has the same density as alcohol.
C.
Water has a greater density than alcohol.
D.
Alcohol has a greater density than the ice cubes.

Answer:

C. Water has a greater density than alcohol.

Explanation:

From the experiment, it can be shown that water has a greater density than the alcohol.

The ice cube is able to float in the water because, the density of the ice is less than the density of the water.

 Density of ice < Density of water

So, the ice cube sinks in alcohol because the density of the ice cube is greater than the density of the alcohol.

 Density of ice > Density of alcohol

Therefore, we can assume that since the density of ice is greater than density of alcohol, then the density of water is greater than that of the alcohol.

Which of the following elements has the lowest ionization energy?
larisa86 [58]

Answer:

Rb

Explanation:

Ionization energy is defined required energy to eliminate or remove an electron from an ion or atom.

From the given elements Rb or Rubidium has the lowest ionization energy as it has lowest shielding effect, so it easy to remove electron from it's shell.

The ionization energy generally decreases from top to bottom in groups due to lower shielding effect and outer electrons are loosely packed so easy to remove and increases from left to right across a period because of valence shell stability.

Rubidium has atomic number 37 and lies below than other given elements and also placed in the left side in the periodic table.

Hence, the correct option is Rb
