Amolecule of ethylamine is made up of two carbon atoms, seven hydrogen atoms, and one nitrogen atom. the molecular formula is c2h7n. the reactive group in ethylamine is nh2. write its condensed structural formula.

The condensed structural formula of an ethylamine is .

Explanation:

Molecular formula : It is a formula which gives the information regarding different types of atoms and number of atoms in a molecule of an compound.

Condensed structural formula : It is a formula in which the lines are used between the bonded atoms and the atoms are also shown in the structural formula.This formula gives us the picture of positions of the atoms.

Given molecular formula of ethylamine :

The condensed structural formula of an ethylamine is :

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
