A Beta particles is emitted when an atom of 85Kr spontaneously decays.
Is there multiple choice answers
Answer:
Explanation:
The equation of the reaction:
Nitrogen gas N₂ reacts with Hydrogen as H₂ to produce ammonia NH₃;
N₂ + H₂ → NH₃
The balanced equation is ;
N₂ + 3H₂ → 2NH₃
The mole ratio is the ratio of the coefficients of the combining reactants;
1 mole of N₂ combines with 3 mole of H₂;
So;
Answer:
Chlorine gas is the limiting reactant
11.57 g
Explanation:
The equation of the reaction is;
2Al(s) + 3Cl2(g) -----> 2AlCl3(s)
The limiting reactant will produce the least number of moles of AlCl3.
For Al
Number of moles reacted = 2.43 g/27 g/mol = 0.09 moles
2 moles of Al yields 2 moles of AlCl3
0.09 moles of Al yields 0.09 * 2/2 = 0.09 moles of AlCl3
For Cl2
9.22g/71g/mol = 0.13 moles
3 moles of Cl2 yields 2 moles of AlCl3
0.13 moles of Cl2 yields 0.13 * 2/3 = 0.087 moles of AlCl3
Hence Cl2 is the limiting reactant
b) Mass of product produced = 0.087 moles of AlCl3 * 133g/mol = 11.57 g
