<span>On a very small scale, the numbers of particles of each substance in a reaction are represented by the coefficients in the balanced chemical equation describing the reaction. Hope this answers the question. Have a nice day.</span>
Answer:
a. It will accept one electron to complete its outer shell.
Explanation:
Chlorine is in Group 17, so it has <em>seven valence electrons</em>, one short of a complete outer shell.
Thus, it will accept an electron from sodium to complete its outer shell.
Answer:
0.492 lb/in^3
Explanation:
From Density of Mercury (13.6g/cm3) given,
Mass = 13.6g
Volume = 1cm3
Now we covert these variables as follows :
For Mass:
454 g = 1 lb
13.6g = 13.6/454 = 0.03lb
For volume:
2.54 cm = 1 in
1cm = 1/2.54 = 0.394in
Volume = (0.394in)^3 = 0.061 in^3
Density = Mass /volume
Density = 0.03lb/0.061 in^3
Density = 0.492 lb/in^3
