Like gases, plasmas have no fixed shape or volume, and are less dense than solids or liquids. But unlike ordinary gases, plasmas are made up of atoms in which some or all of the electrons have been stripped away and positively charged nuclei, called ions, roam freely.
Elements combine in three general ways. In<u> ionic</u> compounds, electrons are transferred from one element to the other, whereas in <u>covalent </u>compounds, electrons are shared between atoms. Third, in <u>metallic </u>bonding, electrons are shared between a large number of atoms in an electron sea.
Ionic compounds are compounds in which a free electron is transferred to another atom and a bond is formed. Ionic bonds occur in metal ions.
In liquid compounds, covalent bonds are formed. In covalent bonds, electrons are shared with each other,
The third type of bond is the metallic bond. In this type of bond, atoms are packed tightly and a free electron pool travels in between them.

Answer:
Freezing point = 1.25
Explanation:
If we increase the concentration of the solution, the concentration of H+ does not change.
Convert 2.5% in to decimal
2.5% = 2.5 ÷100
= 0.025
The freezing point = 0.025 × 50
= 1.25
Magma- hot fluid or semifluid material below or within the earth's crust from which lava and other igneous rock is formed by cooling. Hope this helps!
