How many molecules (not moles of nh3 are produced from 5.01×10?4 g of h2?
Irina-Kira [14]
2,02g     -------    6,02×10²³
5,01×10⁴g  ---    x

x=\frac{5,01*10^{4}g*6,02*10^{23}}{2,02g}=14,93*10^{27}

N₂         +        3H₂       ⇒           2NH₃
1mol      :        3mol        :           2mol
                       18,06×10²³  :       12,04×10²³
                       14,93×10²⁷  :        y

y=\frac{14,93*10^{27}*12,04*10^{23}}{18,06*10^{23}}\approx9,95*10^{27}

The nuclear reaction that occurs by combining two or more lighter atoms into a larger one is called what?
Yuri [45]
The nuclear reaction that occurs by combining two or more lighter atoms into a larger one is called nuclear fusion. As a result of this reaction a huge amount of energy is released.  
Nuclear fission is the opposite process of nuclear fusion when the atom splits into several smaller atoms.
