Answer:
liver and esophagus.
Explanation:
Kidneys are part of the endocrine system, trachea and bronchi are part of the respiratory system
I think the correct answer would be false. The atomic mass of chlorine does not represent the mass of the most common naturally occurring isotope of chlorine. The atomic mass of any compound is the average of the atomic masses of the naturally occurring isotopes of an element. <span />
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:
i think this would be an example of a physical change because here the substance is changing directly from a solid to a gas without passing through the liquid state which means that the composition of the substance has not changed and remains the same. This is also called sublimation.
I believe it is BaS I hope this helps!
