The pencil attached to the negative terminal of the battery collects hydrogen gas while the one connected to the positive terminal collects oxygen.
Answer:
(b) amino group
e) carboxyl group
Explanation:
The functional group in an organic compound distinguishes it from other compounds. It is usually the site where chemical reactions takes place.
CH₃-HC(NH₂)-COOH
There are two functional groups in this organic compoud:
- The NH₂ group is called the amino group
- The COOH is a carboxyl group
The third one is the correct answer :)
Answer:
We know that, composition of HNO3 is Hydrogen, Nitrogen and oxygen. Total number of atoms = 3+1+1=5 atoms are present in 1 molecule of HNO3.
I think the correct answer from the choices listed above is the third option. The element that will have similar chemical properties to francium would be rubidium since they are in the same column. <span>Groups of </span>elements in the same<span> column have similar </span>chemical <span>and physical </span>properties<span>, reflecting the periodic law.</span>
