Each molecule has exactly the same shape and design.3. In an attempt to make a complex set of variables fit a man-made model, new facts andevents always fit the old model.4. The bonds in water are not similar to those in carbon tetrachloride.5. The characteristic of elements un-pairing already paired electrons in order to form bondsis called hybridization.6. The word hybrid means "a mixture of two different sources."7. In chemistry a hybrid bond is a mixture of different types of electrons.8. The halogen family has a low tendency to gain electrons.9. The most common compound of a halogen is probably sodium chloride, table salt.10. All members of the inert gas family react with other elements.11. In a hybrid bond, the bonding electrons are at a compromise between orbitals.12. All electrons attract each other.13. When a molecule is lopsided (nonsymmetrical), with electrons not symmetricallydistributed, the molecule is polar.14. If all electrons are evenly distributed in a molecule, the molecule is symmetrical.15. Electronegativity can influence the polarity of a molecule.16. When electrons in a molecule are shifted away from one atom and towards another, themolecule has a dipole (two-pole) and is said to be nonpolar. (p36)17. Hydrogen (electronegativity = 2.1) is considered an electron hog in LiH, Li>H.18. When beryllium bonds with two hydrogen atoms, BeH2, a symmetrical, linear molecule isformed.H-Be-H

11. In a hybrid bond there is mixing of the orbitals where electrons are compromised hence this is…

CONCLUSIONS: In general, the boiling points of compounds increase down a group in the periodic table. The melting points and boiling points for the hydrogen compounds of group 6A elements are in the table below. Melting Point (°C) Boiling Point (°C) H₂O 0.0 100.0 H₂S -82.0 -60.0 H₂Se -65.7 -41.2 H₂Te -49.0 -2.2 Use your understanding of chemistry to propose an explanation for the anomaly in the trend for the hydrogen compounds of group 6A elements shown in the table.
Order these chemical species by increasing pH of an 0.1 M aqueous solution of each. That is, imagine making an 0.1 M solution of each species. Select 1 next to the species that makes the solution with the lowest pH. Select 2 next to the species that makes the solution with the next higher pH, and so on. Notice that some of the rankings have been filled in for you already. Also notice that water is on the list. For that particular case, just compare the pH of pure water to the pH of the other solutions. Note for advanced students: for all charged species, you may assume the necessary counterions act as neither acids nor bases. relative pH of 0.1 M aqueous solution species H,0 4 НСОО (Choose one) ▼ Cio, 6 HCIO, (Choose one) ▼ HSO4 |(Choose one) ▼ OH (Choose one)
