Answer:
carbon because organic compounds are made up of hydrogen and carbon
Electrons move in what is called an electron cloud. Each atom has its own electron cloud associated with it. This region simply represents an area or likelihood within that an electron of corresponding energy can be found within.
Answer:
HBr + H₂SO₄ → SO₂ + Br₂ + H₂O An oxidizing agent is a substance that itself becomes reduced and oxidizes the other chemical species in the reaction mixture. A reducing agent is similar, except that it becomes oxidized and reduces the other substance. In the reaction, the valency of bromine changes from -1 to 0, so it is oxidized
Explanation:
There can be three definitions of a base: Arrhenius base, Lewis base or Bronsted-Lowry base. Isoquinoline acts specifically as a Bronsted-Lowry base, which is a proton acceptor. Also, it acts as an Arrhenius base because it produces OH- ions after the reaction. The net ionic equation is:
<span><em>C</em></span><em>₉</em><span><em>H</em></span><em>₇</em><span><em>N (aq) + H</em></span><em>₂</em><span><em>O ---> C</em></span><em>₉</em><span><em>H</em></span><em>₇</em><span><em>NH</em></span><em>⁺</em><span><em> (aq) + OH</em></span><em>⁻</em><span><em> (aq)</em></span>
