Why does electronic waste that is generated in developed nations get dumped
in developing nations?||

"Developing" countries like china will often be paid an amount by "Developed" countries to handle recyclable/waste materials in an ethical way. Unfortunately, this requires time and money to accomplish. Countries like china will often opt to take the lump sum and simply dump the waste instead of handling it properly. It's simply the cheapest and most effective way to make money in that field.

Explanation:

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
