Answer:
A) Polar molecules have a non-zero net dipole moment. Both CO2 and H2O have two polar bonds. However the dipoles in the linear CO2 molecule cancel each other out, meaning that the CO2 molecule is non-polar. The polar bonds in the bent H2O molecule result in a net dipole moment, so H2O is polar.
B) In PCl5, in addition to equitorial bonds which lie in the same plane, there are axial it suffers more repulsion it is longer than the other bonds; hence PCl5 decomposes to form PCl3. So PCl5 is highly reactive. Source(s): 5 Heavy ElectroNegative atoms in One Molecule Lone Pair.
C) In h2o there is hydrogen bonding because oxygen has a high electronegativity (only second to flourine). so, the hydrogen atoms from other molecules of water forms a hydrogen bonds with oxygen resulting in intermolecular hydrogen bonding. therefore at room temperature h2o is a liquid and h2s is a gas.
Hope this helps also can you answer my question after since I helped you prepare for your exam.
Explanation:
Answer:
Solid, liquid, gas
Explanation:
add thermal energy to solid and it becomes liquid, add thermal energy to liquid it becomes gas
Several pieces of equipment can do this, including the Bunsen burner, laboratory oven, hot plate and incubator.
Answer:
A great example would be a fish, it needs the water to breathe just like how we humans need oxygen. If a fish were to get out of the water it would die.
Explanation:
Your answer would be respiration. This would be your answer because, plants take in carbon dioxide, and animals, including humans, breath oxygen. I hope this had helped you out.
