I think the amount would be a 0.4998 mol
I did moles=mass(g)/A,r
=12.5/24.3 to get that

7. Name the elements found in nature in diatomatic form.
8. What is the difference between double and triple single link?
Answer:
a. 63.2%
b. 11.7%
c. 73.3%
d. 0.995%
e. 55.5%
Explanation:
An ionic compound is a compound that is formed by ions, so one of the elements must donate electrons (which is the cation, the positive ion), and the other will receive these electrons (which is the anion, the negative ion).
The power of an element has to attract the electrons is called electronegativity, and so, as higher is the difference of electronegative of the elements, it is more probable that one of them will "still" the electrons and will form an ionic compound. The percent of this ionic character can be found by the Pauling's equation:
*100%
Where
is the electronegativity difference of the elements. Thus, consulting an electronegativity table:
a.
= 1.5
= 3.5
*100%
%IC = 63.2%
b.
= 1.6
= 2.1
*100%
%IC = 11.7%
c.
= 0.7
= 3.0
*100%
%IC = 73.3%
d.
= 1.7
= 1.9
*100%
%IC = 0.995 %
e.
= 1.2
= 3.0
*100%
%IC = 55.5%
Answer:
Both require time, but velocity requires displacement and speed requires distance
Explanation:
For calculating speed we require time and distance because speed is defined as the distance per unit time and as speed is a scalar quantity it does not have any direction
But for calculating the velocity we require time as well as displacement because velocity is defined as the displacement per unit time and as velocity is a vector quantity it has direction
Displacement is the shortest distance between the initial position and the final position and it has a specified direction as well
