7 protons means that N atom has 7 electrons

1st level can have only 2 e⁻, and we have left over of 7-2=5 e⁻, that will go on the second level.

B. 2,5

What does a chemical bond results from a rearrangement of?
Dmitriy789 [7]

Atoms

Explanation:

Chemical bonds results from the rearrangement of atoms in a chemical species.

It deals with the various attractive forces joining chemical species togethe.

  • When atoms are re-arranged, they form chemical bonds that leads to production of new compounds.
  • This is made possible by the exchange or sharing of electrons.
  • The driving force for most interatomic bonding is the tendency to have completely filled outer energy levels like the noble gases.
  • When atoms are re-arranged in compounds they lead to the production of chemical bonds.

Why are the molecules of hydrocarbons nonpolar?
laiz [17]
<span>This is not the case in the hydrocarbon tail. The electronegativity of hydrogen and carbon are very similar, so the electron cloud is distributed evenly over the two atoms. Carbon-hydrogen bonds are said to be non-polar because they do not have positive and negative poles within themselves. Hope this helps. </span>

Phosphate buffers are commonly used in biological research. If a small amount of strong acid is added to a buffer solution that
lozanna [386]

Answer:

A) [H3PO4] will increase, [KH2PO4] will decrease, and pH will slightly decrease.

Explanation:

A buffer is a solution which resists changes to its pH when a small amount of acid or base is added to it.

Buffers consist of a weak acid (HA) and its conjugate base (A–) or a weak base and its conjugate acid. Weak acids and bases do not completely dissociate in water, and instead exist in solution as an equilibrium of dissociated and undissociated species. When a small quantity of a strong acid is added to a buffer solution, the conjugate base, A-, reacts with the hydrogen ions from the added acid to form the weak acid and a salt thereby removing the extra hydrogen ions from the solution and keeping the pH of the solution fairly constant. On the other hand, if a small quantity of a strong base is added to the buffer solution, the weak acid dissociates further to release hydrogen ions which then react with the hydroxide ions of the added base to form water and the conjugate base.

For example, if a small amount of strong acid is added to a buffer solution that is 0.700 M H3PO4 and 0.700 M KH2PO4, the following reaction is obtained:

KH₂PO₄ + H+ ----> K+ + H₃PO₄

Therefore, [H₃PO₄] will increase, [KH₂PO₄] will decrease, and pH will slightly decrease.:
