5. Explain why both diet and regular soft drinks can damage the enamel on the surface of teeth.

2 answers:

7 0

Diet sodas and other sugar-free drinks are usually highly acidic, which weakens the enamel on your teeth and makes them more susceptible to cavities and dental erosion. The level of phosphoric acid, citric acid, and/or tartaric acid is usually high in sugar-free drinks so it's best to avoid them

When you drink soda, the sugars it contains interact with bacteria in your mouth to form acid. This acid attacks your teeth. Both regular and sugar-free sodas also contain their own acids, and these attack the teeth too. With each swig of soda, you're starting a damaging reaction that lasts for about 20 minutes.

Can some atoms exceed the limits of the octet rule in bonding? If so, give an example.

harkovskaia [24]

Answer:

Yes. Example: Sulfur hexafluoride (SF₆) molecule

Explanation:

According to the octet rule, elements tend to form chemical bonds in order to have 8 electrons in their valence shell and gain the stable s²p⁶ electronic configuration.

However, this rule is generally followed by main group elements only.

Exception: SF₆ molecule

In this molecule, six fluorine atoms are attached to the central sulfur atom by single covalent bonds.

Each fluorine atom has 8 electrons in their valence shells. Thus, it follows the octet rule.

Whereas, there are 12 electrons around the central sulfur atom in the SF₆ molecule. Therefore, sulfur does not follow the octet rule.

Therefore, the SF₆ molecule is known as a hypervalent molecule or expanded-valence molecule.

First and last sentence .‍♀️

Explanation:

An important thing to keep in mind about the Reading Comprehension section of the GRE as we use PowerPrep online to study is that it is just that—reading comprehension. In other words, as difficult as it may seem, and it can be pretty tricky, the test makers will always give us all the information we need in the passage to answer the question.
