Compound consisting of a sodium ion (Na+) with a plus one charge and a fluoride ion (F-) with a minus one charge. Hope I helped!! :)
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.
There are 0.454 kg in 1 lb
Cross multiply
0.454 kg = 1 lb
X kg. = 50 lb
50* 0.454 = 22.7 kg
Answer : 22.7 kg in 50 lbs
The statement that is an alloy is just another word for a chemical compound of fixed composition that is made of two or more metals is false.
An alloy refers to the mixture of the elements in which the parent element is the metal. An alloy is produced by the amalgamation of any element, that is, metal or non-metal to better the feature of the parent metal. The whole components in the alloy are combined to produce a mixture of fixed composition, but not a chemical compound, and it is not essential that the elements involved are metals. Thus, the mentioned statement is false.
