What types of bonds or interactions are overcome when a nonmetal extended network melts?
STatiana [176]

Covalent bonds or interactions are overcome when a nonmetal extended network melts.

Typically, nonmetals form covalent bonds with one another. A polyatomic ion's atoms are joined by a form of link called covalent bonding. A covalent bond requires two electrons, one from each of the two atoms that are connecting.

One technique to depict the formation of covalent connections between atoms is with Lewis dot formations. The number of unpaired electrons and the number of bonds that can be formed by each element are typically identical. Each element needs to share an unpaired electron in order to establish a covalent bond.

Therefore, covalent bonds or interactions are overcome when a nonmetal extended network melts.

A solution at ph 10 contains __________ than the same amount of solution at ph 8.
Sindrei [870]

100 times less H+

A solution at ph 10 contains<u> </u><u>100 times less H+</u> than the same amount of solution at ph 8.

<h3>The pH scale: How does it function?</h3>
  • The pH scale determines how acidic or basic water is.
  • The range is 0 to 14, with 7 representing neutrality.
  • Acidity is indicated by pH values below 7, whereas baseness is shown by pH values above 7.
  • In reality, pH is a measurement of the proportion of free hydrogen and hydroxyl ions in water.

<h3>How does the pH change when two acids are combined?</h3>
  • An acid's strength increases with the quantity of hydrogen ions it releases.
  • The pH of the strong acids is between 1 and 2.
  • We may observe that there is no response when two acids of the same strength are combined.
  • It's because the end product will be neutral and the pH won't change.

<h3>How is pH value determined?</h3>

There are two ways to measure pH:

  • colorimetrically with indicator fluids or sheets
  • electrochemically with electrodes and a millivoltmeter for greater accuracy (pH meter).

What happens to energy when methane increases?
Zanzabum

Answer:

How does methane gas affect the environment?

If methane leaks into the air before being used — from a leaky pipe, for instance — it absorbs the sun's heat, warming the atmosphere. For this reason, it's considered a greenhouse gas, like carbon dioxide.
