Answer:
C. Lithium is most easily oxidized of the metals listed on the activity series and therefore it will most easily give electrons to metal cations
Explanation:
"Lithium" is a type of alkali metal that has a "single valence electron." Since it is a reactive element, it easily gives up an electron when it is combined with other elements. Such giving up of electron is meant to create compounds or bonds.
Among the common metals listed, "lithium" is the most easily oxidized. This means that it donates its electrons immediately. Such combination makes it exist as a<em> "cation"</em> or <em>"positively-charged."</em>
So, this explains the answer.
Answer:
The answer to your question is: the first option
Explanation:
Meter is a unit of length in the SI, international system of units. Its symbol is m.
Nanometer is equivalent to 10⁻⁹ meters, as its name says it is used to measure extremely small particles.
-To solve this problem we use a rule of three.
1 meter ⇒ 10⁹ nanometers
x meters ⇒ 670 nanometers
Simplify
x = (670 x 1)/( 10⁹)
x = 6.7 x 10 ⁻⁷ meters
Condensation.
If you think about the condensation you may find on your windows on a frosty morning, this may help you to remember :]
