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.
Water is polar in that the hydrogen atoms bear a partial positive charge, whereas the oxygen atom bears a partial negative charge, due to the electronegativity of oxygen. ... Water disrupts ionic bonds and hydrogen bonds.

The element that is reduced gains electrons. In this case Fe is gaining electrons
Answer:
Graphite (/ˈɡræfaɪt/), archaically referred to as plumbago, is a crystalline form of the element carbon with its atoms arranged in a hexagonal structure. It occurs naturally in this form and is the most stable form of carbon under standard conditions. ... Graphite is used in pencils and lubricants.
