CHEMISTRY QUESTIONS - TRUE OR FALSE. Please Answer These Questions With TRUE or FALSE.

1. Ions that end with -ous have a smaller charge than those ending with -ic.
2. Only Cations may have more than one charge or oxidation number.
3. Ions ending in -ite have more oxygen atoms than those ending in -ate.
4. When naming a single element as the anion in a binary compound you take the root word and change the ending from -ide to -ine.
5. BINARY compounds have only 2 elements combined, representing bonds that are either ionic or covalent.
6. Parentheses are NOT required when writing poly atomic ions unless there is a multiple of the same ion to be written in the chemical formula.
7. Roman Numerals are used for ANY Metal regardless of the Oxidation Number stated.
8. Anions are positive ions and Cations are negative ions.
9. When writing chemical formulas it is important to make sure the overall charge for all elements equals zero.
10. Write symbols for ions side by side (+) on the left, (-) on the right.

Explanation:

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
