Answer:
B
Explanation:
you're moving the decimal 8 spots to the left so it can only be B
Answer:
Silicon-28
Explanation:
To estimate the isotope with the highest percentage of abundance, we look at which of the isotopes have the closest resemblance to the value of the final atomic mass.
From what is given, it can be observed that the isotope with the highest value is that of the 28 because it can be seen that it is large enough to have affected the value of the isotope near it.

Answer:
c) hydrogen bonding.
Explanation:
Like water molecules which are H2O, hydrogen disulfide also has a bent shape. However, unlike water, it cannot have hydrogen bonding. Why? Because hydrogen bonding only occurs with nitrogen, oxygen, and fluorine. I haven't heard of disulfide linkages. And yes, H2S has London dipersion forces. All polar molecules have LDFs. But greater than that, H2S has dipole-dipole forces. Event though it is a dipole-dipole bond, it is still highly electronegative.
