Answer:
Alkanes contain only carbon-carbon and carbon-hydrogen bonds. Because carbon and hydrogen have similar electronegativity values, the C—H bonds are essentially nonpolar. Thus, alkanes are nonpolar, and they interact only by weak London forces.

Answer:
I believe 1+
Explanation:
when Na loses 1 electron in the outer shell it has 8 valence protons on it's new most outer shell. so now it has 11 protons and 10 electrons. that extra proton (positively charged) adds one extra charge. so +1
Answer:
Concentration of A at equilibrium = 1 - 0.5 = 0.5 M
Explanation:
Equilibrium constant = 0.5
Initial concentration of A = 1 M
Initial 1 0 0
At equi. 1-x x x
Equilibrium constant = ![\frac{[B][C]}{[A]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BB%5D%5BC%5D%7D%7B%5BA%5D%7D)
on solving,
x = 0.5 M
Concentration of A at equilibrium = 1 - 0.5 = 0.5 M
Answer:
A for 1 and 4 B for 2 and 3 ..........
