Answer: 18.0 moles of [tex]BH_3[/tex] will be produced when 27.0 moles of [tex]H_2[/tex] completely react.
Explanation:
The balanced chemical equation is:
[tex]2B+3H_2\rightarrow 2BH_3[/tex]
According to stoichiometry :
3 moles of [tex]H_2[/tex] produce = 2 moles of [tex]BH_3[/tex]
Thus 27.0 moles of [tex]H_2[/tex] will produce=[tex]\frac{2}{3}\times 27.0=18.0 moles[/tex] of [tex]BH_3[/tex]
Thus 18.0 moles of [tex]BH_3[/tex] will be produced when 27.0 moles of [tex]H_2[/tex] completely react.

what is the most important part of an Atom? Why?
Answer:
I would say proton and electron are the two most important subatomic particles in an atom
Explanation:
The number of protons inside a nucleus must equal to the number of electrons outside of the nucleus. This number determines all the chemical properties of the atom, which governs the behaviors of all matters in our world.
