Well I have no clue on what your class is doing but to me, it looks like B. the dependent variable also increases
Yeah, it sure does
Hope this helps!
Answer:
Choice C - a mixture
Explanation: I just did the question
Answer:
B 1.87×10^-²
Explanation:
20.1797 g Neon = 1 mol
0.378 g Neon = y
(Cross multiply)
20.1797y= 0.378 x 1
(Make y the subject of the formula)
y = 0.878/ 20.1787
y = 0.0187317
y = 0.0187 approx
y = 1.87 x 10^-²
Due to periodic trends potassium would lose its one valence electron to have a more stable electron configuration equivalent to that of argon, which is a noble gas with a full octet. Fluorine would gain one valence electron to get a full octet equivalent to that of neon. Since potassium lost an electron it now has a positive charge and since fluorine gained an electron it is now negative. Since both are more stable this way as a full octet they will no longer exchange electrons but the positive potassium and negative fluorine will pull towards each other strongly forming an ionic bond.
