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.

Answer:</h3>
Lead-205 (Pb-205)
<h3>
Explanation:</h3>
<u>We are given;</u>
We are supposed to identify its product after an alpha decay;
- Polonium-209 has a mass number of 209 and an atomic number of 84.
- When an element undergoes an alpha decay, the mass number decreases by 4 while the atomic number decreases by 2.
- Therefore, when Po-209 undergoes alpha decay it results to the formation of a product with a mass number of 205 and atomic number of 82.
- The product from this decay is Pb-205, because Pb-205 has a mass number of 205 and atomic number 82.
- The equation for the decay is;
²⁰⁹₈₄Po → ²⁰⁵₈₂Pb + ⁴₂He
- Note; An alpha particle is represented by a helium nucleus, ⁴₂He.
