A.)a radio telescope
Answer:
1. molecular
2. molecular
3. molecular
Explanation:
Molecular compounds typically exhibit covalent compound characteristics. They are pure substances formed when atoms are linked together by sharing electrons while ionic compounds are formed due to the transfer of electrons. Molecular substances tend to melt at moderately warm temperatures (i.e. 50° C) and it is overlapping as seen in compound 1, which makes it to be molecular in nature.
Molecular compounds are not affected by conductivity, hence they are electrically neutral.
Molecular compounds have a strong smell and have freezing and boiling point at accessible temperatures. A clear liquid at room temperature which has a fruity strong smell can be an organic compound. These organic compounds made up of covalent bonds and are molecular in nature.
Molecular hydrogen (H2)
Hydrogen (H2O2)
Nirous Oxide (N2O)
Methane (CH4)
I am so sorry if this is incorrect I did it a long time ago!
