Answer:
43.75 g of Nitrogen
Explanation:
We'll begin by calculating the mass of 1 mole of NH₄NO₃. This can be obtained as follow:
Mole of NH₄NO₃ = 1 mole
Molar mass of NH₄NO₃ = 14 + (4×1) + 14 + (3×16)
= 14 + 4 + 14 + 48
= 80 g/mol
Mass of NH₄NO₃ =?
Mass = mole × molar mass
Mass of NH₄NO₃ = 1 × 80 = 80 g
Next, we shall determine the mass of N in 1 mole of NH₄NO₃.
Mass of N in NH₄NO₃ = 2N
= 2 × 14
= 28 g
Thus,
80 g of NH₄NO₃ contains 28 g of N.
Finally, we shall determine the mass of N in 125 g of NH₄NO₃. This can be obtained as follow:
80 g of NH₄NO₃ contains 28 g of N.
Therefore, 125 g of NH₄NO₃ will contain = (125 × 28) / 80 = 43.75 g of N.
Thus, 125 g of NH₄NO₃ contains 43.75 g of Nitrogen
Answer: Advantages and Challenges of Nuclear Energy Nuclear energy protects air quality by producing massive amounts of carbon-free electricity. It powers communities in 28 U.S. states and contributes to many non-electric applications, ranging from the medical field to space exploration.
Explanation:
Answer:
General chemical equation
2 M + 3 X₂ → 2 MX₃
Explanation:
When metal reacts with halogens metal halide as a product obtained.
Now oxidation state of metal assume (+3)
and oxidation state for halogen = (+1)
So formula of the metal halide is (MX₃)
Denote the metal as M and halogen as X
the balanced chemical equation
2 M + 3 X₂ → 2 MX₃
So the resulted general equation when metal react with halogen is
2 M + 3 X₂ → 2 MX₃
