which property of water allows it to dissolve many substances?
waters heat capacity
waters melting point
waters density
waters polarity

Explanation:

First Question (Water attracted to charged balloon)

• Water molecules are polar, meaning electrons are unevenly distributed (oxygen is more electronegative, pulling electrons). A charged balloon will attract the polar water molecules. The correct option must mention uneven electron distribution in water and attraction to a charged balloon.
• Analyzing options:
• Option 1: Says attracted to uncharged balloon (wrong, balloon is charged).
• Option 2: Says even electron distribution (water is polar, so electrons are uneven; wrong).
• Option 3: Even distribution and uncharged balloon (both wrong).
• Option 4: Uneven distribution in water and attraction to charged balloon (correct).

• Water dissolves many substances because of its polarity. Polar water molecules can interact with and surround polar or ionic solutes, breaking them apart.
• Analyzing options:
• Water’s heat capacity: Related to heat absorption, not dissolving.
• Water’s melting point: Related to state change, not dissolving.
• Water’s density: Related to mass/volume, not dissolving.
• Water’s polarity: Correct, as polar substances dissolve in polar solvents (like dissolves like), and water’s polarity allows it to interact with many solutes.

Answer:

The uneven distribution of the electrons in the water molecule are attracted to the charged balloon.
