ASM midterm

A Compound that is being dissolved is called a

• Solution
• Solute
• Solvent
• Suspension

Why can water have no net charge but have slight charges in different parts of the molecule?

• The oxygen end is slightly negative and the hydrogen end is slightly positive
• The hydrogen end is slightly negative and the oxygen end is slightly positive
• The hydrogen and oxygen ends change in polarity
• Because it is hydrophobic

Attractions between water molecules are called

• Covalent bonds
• Ionic bonds
• Polar bonds
• Hydrogen bonds

Water is a universal solvent because it...

• It can be found anywhere
• It freezes when it gets cold
• floats when frozen
• Dissolves most substances

Which types of compounds dissolve easily in water?

• Polar and Nonpolar
• Polar and Ionic
• Nonpolar and Ionic
• Covalent and Nonpolar

Elements on the LEFT side of the periodic table will most likely form:

• Positive ions
• Negative ions
• Neutral Ions
• None of these

An ionic bond forms when atoms ___________ electrons.

• gain
• share
• increase
• transfer

Which type of bond has a transfer of an electron from on atom to another?

• Polar Covalent 
• Non Polar Covalent
• Ionic
• Metallic

If an atom loses two electrons what charge will it have?

• + 2
•  - 2
• +1
• -1

How are covalent bonds explained?

• When one atom takes the other atom's electron
• When the atom shares an electron with an another atom
• When the two nucleus merge
• When the neutrons leave the nucleus
