Answer:
The P-H bonds are more polar than the N-H bonds.
Explanation:
Phosphine is a polar molecule with non-polar bonds. The phosphorus atom is bonded to three hydrogen atoms and the phosphorus atom has a lone pair of electrons. Since hydrogen and phosphorus are equal in electronegativity, it implies that they attract the shared pairs of electrons the same amount,hence bonding electrons are shared equally making the covalent bonds non-polar.
The lone pair of electrons on phosphorus causes the molecule to be asymmetrical with respect to charge distribution this is why the molecule is polar even though the are non-polar bonds in the molecule.
Looking at the values of electro negativity stated in the question, one can easily see that the difference in electro negativity between nitrogen and hydrogen is 0.9 while the difference in electro negativity between phosphorus and hydrogen is zero. It is clear that NH3 is naturally more polar than PH3 since each individual N-H bond in NH3 is a polar bond while the individual P-H bonds in PH3 are nonpolar.
Answer:
False
Explanation:
In Nuclear plants accidents such as explosions can occur which may lead to loss of life or severe injuries.
Nuclear energy production does not produce emissions but it produces radioactive waste which have to be stored adequately to prevent pollution. Since nuclear waste cannot be destroyed, measures have to be taken to adequately store the waste.
If the nuclear plant is being attacked, it can be used as a nuclear weapon to create disaster
Indicates that the planet does not have an atmosphere. If the planet had an atmosphere is would erode away at the meteors before they hit the surface.
if it is edible you can taste it if it taste bitter its a base and if it taste sour then it is a acid if it taste like nothing like water would it would be a neutral substance.you could also order a ph tester which is just a liquid that you drop in it.
