Answer:

Two elements in same group having similar properties.

Explanation:

The elements shows similar properties if they have same number of valance electrons.

As we move left to right in periodic table the number of valance electrons increases in case of every element

When we move top to down in the group of periodic table the number of valance electrons remain same. So the elements in same group shows similar properties.

For example:

Fluorine and chlorine are present in same group, both have same valance electrons so they shows similar properties.

Electronic configuration of fluorine.

F₉ = [He] 2s² 2p⁵

Electronic configuration of chlorine.

Cl₁₇ = [Ne] 3s² 3p⁵

Both have same number of valance electrons that's why showing similar physical and chemical properties.

Which mineral(s) might you be examining if you place some hydrochloric (hcl) acid on a sample and it fizzes?
makvit [3.9K]
The minerals that one might be examining if you place some hydrochloric acid on a sample and it fizzes are Calcite and Dolomite.
Calcite and dolomite are very similar minerals. Both have the same hardness, the same rhombohedral cleavage, and are found in identical geologic settings. The best way to tell one from the other is the acid test; A drop of 1 M HCl on calcite produces an instant , obvious Fizz; a drop on dolomite produces slow or no obvious bubbling.

Answer:

I got you... 2 amino acids are linked to each other by a peptide linkage. A peptide linkage is formed when carboxyl group of one amino acid combine with the amine group of the other and during this process, a water molecule is removed.  

The given tripeptide will have 2 peptide bonds. To draw the structure of given tripeptide, we will arrange them in the given order and then we will remove 2 water molecules to form 2 peptide bonds.

Hope this helps:)
